Does not matter. Suggest white if using all one color. Does not have the blue or red outer layer that can be affected by vapors from spray urethane foam. Bill Elmer
The color of pex tubing is for easy identification and has nothing to do with performance. Most plumbers use blue for cold lines and red for hot but that is only convention. Sent from my iPhone
It is the same material if that is what you are asking. Use white pex if you are not going to Color code. Sent from iPhone
Original PEX was white/clear. Now it is offered in red and blue also. It is the same tubing for all three, I color code my jobs to make it easier. Red for hot blue for cold.
The color is purely for convenience. There is no structural or chemical difference at all. You can run blue, red or white to any water service! Sent from my iPhone
AquaPEX red vs blue vs white only matter if you care about color coding your pipes; there is no material difference in the products.
No, there is no diff in material between colors. I ran clear throughout my house and just used colored rings. ryan_jpeg
Any of the Uponer aquapex products are suitable for domestic water. The color coding is for convenience. Some products such as hepex are rated for heating systems only.
Does not matter. Can use white, blue or red, but if using one color, I suggest the white. Blue and red have the dye in the outer layer, and it can be affected by vapors from spray urethane foam. Happened to me, but white was not affected. Made it hard to put fittings on the blue and red.
Doesn't matter. You can use colored O-rings to see what pipe have hot or cold water. For hot water supply please use Aquapex tubing and do not oversize tubing ( long time wait at faucet for hot water with large tubing installed) Thanks
Q: Has anyone had experience using this PEX tubing in an automotive or transit application? I am planning to use it for a heating application on a vehicle and the water temps from the heater will be quite high (180F) in order to keep fluid temp high over a long distance of tubing. Also, is there any experience with PEX tubing's performance with vehicle vibration? Any cracking over time?

They have been using Pex in motor homes for years just make sur you use the yards when penetrating through metal. Good luck. Sent from my iPhone
that is way high temp for Pex,Check out the floor heating type of Pex for temp limits. I would be concerned over vibration if it contacts any metal as it lies. Yours Truly Rob Dinnell
The red pex is for hot water bot is not rated for that high of temperatures. Use standard automotive heater hoses. They are have reinforcement fiber in them.
If no one use this tubing in vehicles do not try to use it. I think neoprene rubber hose is best for automotive application. 180F is fine for Aqapex, tubing rate 180F - 100psi, 200F - 80psi. Tubing is fine with vibration w/out mechanical contact. I beleive Propex plastic fittings is no good for Your application but You can use compression fittings. You can use steam rubber hose if pressure/temperature is high. Ebay have listing for steam Goodyear Flexsteel $40 for 50'. This hose can support 250psi for boiling water.
I have not had specific experience but it should be good in this application with a couple of provisions - 1st - guard the tubing from radiant heat from exhaust system (manifold, catalytic converter, exhaust pipe, etc) [do this with heat shield/insulation. 2nd - try to use bends versus fittings to leave extra flex in system (to allow for movement which the engine WILL experience) 3rd - I would use metal fittings where the tubing attaches to the engine or mechanical components. 4th - make sure routing and quick ties keep the tubing away from mechanical abrasion. FYI - crosslinked polyethylene should not become brittle for years - as long as it is not exposed to extended periods of sunlight. Hope that helps Robert Spears
Q: Hi Everyone. I bought this pipe and installed it for my radiant heat system without realizing this pipe does not have an oxygen barrier. I do have a cast iron pump and a Spirotherm Air Eliminator in the system and would like to know if I have to replace it with O2 barrier pipe or that is ok to keep this one. Thank you in advance!

Verified Reply- PexSupply StaffYou could change over to oxygen-barrier tubing, but it would probably be easier just to install a bronze or stainless steel circulator and to isolate the boiler with a heat exchanger if it cannot handle dissolved oxygen.
Hello fellow shopper, We have used this pipe before for radiant heat, but only in a copper and brass system. I would say, change the pipe or the rustable metal in the system.
The lack of an oxygen barrier would imply that slowly, over time, a little oxygen will permeate through the PEX and into the water. Once in the water, the oxygen will react with iron and the iron will rust. However, as the iron rusts, the oxygen is removed from the water stopping further rusting by the same oxygen. But, more oxygen will continue to permeate the PEX. Cast iron is much less prone to rusting than wrought iron or steel; many car engine blocks are made from cast iron and cooled with antifreeze mix which is 50% water. You will probably never have problems. However, there are chemical treatments available that can be added to the water in the closed loop heating system to reduce the possibility of rust. Consult a local hydronic heating system specialist to consider the options.
Q: Is 1 1/4 in aqapex suitable for direct burial in rocky soil? (well to well house) I'm using 2 in sch 80 PVC for the electric. Should I run the Pex inside some 2 in PVC to protect it?
Asked by Mac 14 years ago
Add your answer
Verified Reply- PexSupply StaffIt is approved for direct burial, but we'd recommend a protective sleeve or at least some sand around the pipe for installations in rocky soil.
I would, anything I run underground I sleeve
AquaPex can be buried in the soil but but can not be exposed to UV when it emerges. I would strongly suggest a conduit when/where you can. Conduit will: 1. Protect AquaPex from damaging UV where/when it does get exposed. 2. Provide a first layer defense against digging shovel puncture for future maintenance and landscaping. 3. Makes it easier to replace. 4. Provide protection in the event that a sharp rock with sufficient force causes damage to the Pex.. The Electrical Conduit PVC has long sweeps which is helpful for snaking PEX. I would advise against standard SCH40 PVC as the elbows are less ideal for turning, also pay attention to the direction of the lips when you plan your strategy for snaking to avoid buckling where two sections of conduit come together. 1.25" Pex has an OD of 1.375" 2" PVC SCH40 has an ID of 2.047" and SCH80 has 1.913" Not a lot of margin to snake easily. So if you are going more than 20 feet or making any turns, I'd use 2.5" or 3" PVC conduit..
It is suitable for direct burial if protected in sand etc. For my well to house run, I put mine in a shield pipe, a: because it goes under a driveway b: so that if something does go wrong I can replace the run without digging anything up. c: at times I have a gopher/ground squirrel problem If you use PVC make sure to get sweeps for your turns and if you can limit it to 45 degree turns, pulling it is even easier. Bryan Home Owner
You can sheath it in PVC or bed it in a couple inches of sand.
the pex is fine but 1 1/2 sch 40 pvc is a lot cheaper and just as good.
It is suitable for direct burial but consider the depth you bury it at. Repeated freeze/thaw cycles may likely push rocks against the line to create a cut in it. This is a somewhat common occurence in residential water mains where there is rocky soil AND the line is buried at proper depth. Running in additional conduit to protect the line is probably a good idea.
I have never used PEX for direct burial, but I see nothing wrong with using it that way. PEX is much more forgiving and tougher than previous generation black coil polyethylene piping, and I have used it for direct burial. The beauty of PEX is that you can kink it or it can freeze and it is flexible enough to return to its original properties without splitting or rupturing. Having said that, it can be punctured or cut by probing or digging either with machinery or shovels, but so can PVC, if it is struck hard enough. The only real protection would be to place it inside steel or concrete pipe, and I do not feel that is warranted as long as the location is well known and digging in avoided to the burial depth in that area.
Aquapex is definitely not for direct bury. It's also not rated to freeze so be sure to bury below frostline. ...Wayne
Q: what is coldest temp pex can be exposed to? pumping water from lake to fountain. During winter line still full, no pressure , 10" under ground surface, 1.5 to 2" pipe, exterior air temp min -10F for short periods.

Verified Reply- PexSupply StaffAquaPEX can handle fluid temperatures well below 0°F if it contains glycol, but water will freeze at these temperatures and could cause the tubing to burst.
Not sure on this one but I think it's trouble. I have had 1" pex freeze up at 10 degrees buried 18" down. my fix was to use artic wrap insulation and the bury 36" down.
Supposedly, you can freeze water in Pex, and it will not burst. When the ice melts it goes back to the normal diameter. In other words, it can expand and contract as needed. It has a better cold rating than probably any other type of pipe or tubing. You can also insulate Pex too to help prevent the freezing. Thank You <Õ¿Õ>Mike Starcher
Pex is supposed to help prevent pipe bursting in freezing temperatures but repeated freezing/thawing will deteriorate the pipe and possibly damage the pump. Your best course of action is to bury the pipe 42" deep or at least frost depth for your area. If this is not possible, best back up plan is to run pump in winter ... Moving water is less susceptible to freezing.
Aquapex can freeze and won't be damaged. Sent from my iPhone
A PEX design guide by "Plastics-Pipe-Institute" & "Plastic Pipe & Fittings Association" & "PATH (Partnership for Advancing technology in Housing) & "NAHB Research center" (i.e. industry groups, not one vendor) repeatedly says PEX is resistant to freezing damage. It says as long as the pipe is unconstrained so that it may expand along its length (cautions that may not be the case embedded in a slab) that it normally expands when water freezes and shrinks back once thawed. There are no numbers given as a lower limit, but I would point out that clearly it's expected to survive below freezing, and the transition to freezing with the associated expansion is the single point of danger, assuming you won't be flexing the pipe when colder. It cautions that fittings may not be so resilient. Several sources point out that Wirsbo Uponor brand PEX is the type of PEX that is more flexible than other types of PEX. I would point out that once buried & frozen, you'll have to wait until the ground at that depth is not frozen before the pipe will be thawed, which will be later in the spring than when the top inch of soil warms above freezing. So it seems you should be safe as long as you can ensure that any fittings are drained so they won't be damaged. Joe
If water freezes inside steel, copper OR PEX it will expand. If it expands it will split. PEX empty will withstand very cold temps with no damage. However, with water in it the water does the damage and so it has to be drained in winter time if the water has potential to freeze Sent from my iPad
The pipe does not have a minimum temp spec, but it's not rated for frozen water.
I would not use pex. Pvc would be alot easier to handle. No guarantees for either if frozen. U need drain valves. Sent from my iPhone
Wirsbo Aqua pex is freeze/thaw stable, so it shouldn't break. At that depth it will freeze with water in it. Be safe blow lline out with compressor when not in use. Best insurance against freezing. Eric EZ does IT! P&H
Q: What is the the pressure drop for 2" tubing?

Verified Reply- PexSupply StaffRefer to the link below starting at page 59 for pressure drop charts for Uponor PEX tubing. http://www.uponor-usa.com/~/media/Files/Technical%20Documents/PDAM_P1_3%2008.aspx?sc_lang=en
Pressure drop is dependent on flow rates, type of fluid and elevation. Your question can only be answered if you supply the flow rate and liquid. Sent from my iPhone
I recommend connecting the manufacturer at: http://www.uponor-usa.com/Footer/Contact-Us/Default.aspx.
How fast a water flow will you be using? Here's a link for finding the pressure drop if the flow is under around 5 feet/sec. (50 gal./min. for 2") I'm expecting that PVC flow and PEX flow pressure drops will be similar. Pressure drop is proportional to the square of the flow rate. 50 gal./min. = 5 feet/sec. = 2.5 psi/100' 10 gal./min. = 1 foot/sec. = 0.1 psi/100' At higher flow rates the flow tests to turbulence, and different equations must be used, with pressure losses being higher.

Q: I ordered 1-1/4" Aquapex for a hydronic system and 1-1/4" ProPex fittings that are supposed to be compatible. The tubing is extremely rigid and the fittings are the size of the OD of the tubing. These fittings refuse to fit the PEX. What am I missing?
Asked by Bob 14 years ago
Add your answer
Verified Reply- PexSupply StaffYou must use a proper tool to expand PEX-A tubing before ProPEX fittings will fit inside the tubing. 1-1/4" PEX requires teh current Milwaukee M18 expansion tool or an older manual or electric model.
It appears that you have ordered the correct tubing along with the proper fittings. However Uponor Aquapex requires you to cut the tubing to the proper length and slip on a compression ring that is essentially a larger piece of aquapex that should slip over the cut end of tubing. Then you must have a expansion tool to expand the tubing and ring large enough to slip over the Propex fitting. It will then shrink onto the brass or engineered plastic fitting (depending on what you purchased) and seal. The tool runs a couple hundred dollars. Not sure if really anyone rents them. May have to check with a plumbing supply house if you elect to rent one. I know the big box stores don't have em. They may only rent the brass ring compression tools but the you have the wrong kind of pex and fittings. Good luck. However I do prefer the type of pex you have. Expansion type.
The fittings will not fit into the tube until you expand the tube. Once expanded, the fitting slips in easily and the tube shrinks back down. You need to have a ProPex expander tool to stretch the tube (and the reinforcing ring that you put on the end. Suggest watching a propex fitting installation on youtube.
Tubing that size is very hard to work with and it would be best to use a great gun on the end of the tubing to soften it up. Assuming the sizes you have are right, it should work.
Hi, You cannot use aquapex on a Hydronic system. You have to use heat pex tubing. Also are you using the 1 1/4 pex rings that go over the tubing.
The pro pex fittings require an expanded tool and the correct die, you will also need collars. Get the collars with stops they work better. If you are only making 4 connections, supply and return there is a brass fitting That has a clamping collar by way of two bolts. These require you to heat the pipe to get the fitting in place. Be careful not to burn the pipe. Sent from my iPhone
The tubing is stiff. Warming it will make it easier to bend. However, be careful not to melt or kink it. Go to the Uponor website to look at the specs. 1.25" Aquapex is 1.054" ID and 1.375"OD. 1.25" inserts are 0.989" ID. You need the Milwaukee power expansion tool to stretch the pipe and Propex ring to make it all fit over the fitting. Once stretched and installed, the force sealing it is immense as the pipe and ring shrink onto the fitting. Your parts are probably correct. Without the correct expansion tool, it does not assemble. However, with the tool, ProPEX is wonderful to work with.
If you are able soak the tubing in hot water, it's much easier to work with. I used 3/4" and it seamed to work fine with the fittings, but it it hard to work it around corners.
Q: Can this tubing be used to run back and forth between a water-sourced geothermal heat pump and a water heater - the geothermal unit is also used to preheat the hot water. According to the geothermal manual, the recirculation loop can be exposed to very high temperatures during periods when the heat pump runs many hours for space heating. It has a 60 to 160 degree F operating temperature range.

These are two excerpts from the AquaPEX installation manual. I suggest visiting the Uponor website for further information. Wirsbo AQUAPEX has Standard Grade Hydrostatic Stress and Pressure Ratings in accordance with all four temperatures and pressures listed in Table 1 of ASTM F876. AQUAPEX tubing is tested in accordance with Plastic Pipe Institute (PPI) TR-3 and listed in PPI TR-4. The Standard Grade hydrostatic ratings are: •200°F at 80 psi •180°F at 100 psi •73.4°F at 160 psi Hydronic Heating Systems Uponor Wirsbo AQUAPEX can be used in closed-loop hydronic heating systems operating at sustained temperatures up to 180°F, provided any issues concerning oxygen diffusion are properly addressed. Corrodible or ferrous components may not be used in a system designed with Uponor Wirsbo AQUAPEX unless these components are isolated from the tubing
Yes. The pressure in the line should be about 50 psi. That's well below the 80 psi for which the pex you asked about has a 200 degree F rating. So at anywhere near normal household water pressure you'll be fine connecting up the heat pump & water heater operating up to 160 F. If your neighborhood has water pressure that gets up to anything like 80 psi you would do well to have a water pressure regulator installed between the street supply and your inside plumbing. Most new construction will have such a regulator to protect all the household plumbing by keeping your inside pressure down around 50 psi.
AquaPex tubing is essentially the same as HePex tubing which is used for the heating industry with temperatures around 180°F. The only difference with the HePex is it has an oxygen barrier and AquaPex does not. One tid bit of information, though, Pex tubing becomes very soft when it gets warm, so if you are going overhead with it expect it to droop significantly.

They sell a red colored Pex tubing that is for hot water. It should be fine for your application. Just be sure to size it properly.

That PEX tubing will probably be OK for the temperature and pressure, but it may not be rated for that use according to your local plumbing codes. For example, in California, a few years ago PEX tubing was approved (by CPUC), then the approval was yanked, then it was approved again, for domestic water (hot and cold) with the specific exception that it is not to be used in hot water recirculation systems. From my reading on the topic, there is some concern about chemicals from the tubing leeching into the water when it's recirculated. My view is that the supposed "concern" is most likely a stalking horse for plumbing lobbies who know that PEX can save customers a lot of money, and many more projects become easy DIY projects because of it's ease-of-use. But if the recirculated water is to be part of the domestic water system, i.e. not an isolated HVAC system, it would be wise to check local codes before installing it. - Tim Z Falconer
i think this is the wrong product for heating, pex makes another type for high heat.
I have used PEX tubing in hot temps above 160 degrees and have had no problems. If you are in doubt I suggest you cut a piece or two, 6 inches or so and drop them in boiling water for a minute and then remove. You will find they hold up just fine Sent from my iPad
I would suggest that you use HEPex rather than AUQUAPex. I know HEPex will withstand the temperature range you are working with. If there are any ferrous metal parts (stuff that can rust) in your circulation system between the geothermal unit and your water heater, like a cast iron circulator pump, then you definitely need the HEPex. HEPex has a special barrier that keeps oxygen from migrating into the system, thus preventing rust. This is assuming you have a pressurized "closed system" ( that there are no other areas in your system where oxygen can be introduced into it, like a buffer tank, or expansion tank, that is open to the air). If this is not the case, then you have an "open system" and will need to make sure that you have no ferrous metal parts in your system, i.e., use only copper, brass, and pex piping, and a brass or stainless steel circulator pump.
You should have no problem as this is within the performance range for this tubing if you assume the pressure is within limits(<80psi). It would be under virtually the same temperature and pressure when used for a hot water supply line. The failure point for the tubing is inversely proportional to the temperature, that is the higher the temp the lower the failure pressure. You should pay attention to the setting on the water heater so you don't overheat the water. but 160 degree water should not be a problem and I doubt that you will need to heat the water to that temp anyway. Most geothermal systems will work quite well with 90 degree water.
Q: Can pex be used underground as the supply line from the meter?
Asked by Benny 14 years ago
Add your answer
Verified Reply- PexSupply StaffYes, PEX tubing is approved for direct burial. Check your local codes to make sure it is approved in your area.
Yes, for underground installation. Be sure to check with your local authority having jurisdiction as local codes may vary.
Benny, In short yes you can. Can PEX be used for underground cold-water service applications? Yes. Although the enhanced temperature resistance of PEX makes it particularly suitable for hot- and cold-water interior plumbing applications, it also makes an excellent underground water service piping. The new AWWA C904 standard also applies to PEX used in this application. PEX can be installed using the same fittings recommended for copper tube sized SDR-9 polyethylene tubing. However, make sure to check with your local plumbing official to verify its use in the local ordinance. Jim

Q: Can I use the PEX copper crimp rings with this Uponor tubing?
Asked by Jeff 14 years ago
Add your answer
Verified Reply- PexSupply StaffYou can. AquaPEX, along with all other PEX-A tubing, works with the same fittings as PEX-B and PEX-C tubing. PEX-A, however, is the only grade of PEX that also works with expansion-type fittings.
Hi, Yes you can use it.
No. Uponor tubing doesn't use copper crimp rings. Uponor tubing doesn't get crimped. It used a plastic sleeve that you slip over the tubing. Then using an expander tool, you expand the tubing/sleeve together and insert the fitting. The memory in the tubing & sleeve will cause it to shrink back over the fitting creating a seal.
Despite what the manufacturers say, all PEX materials that adhere to the same standards are interchangeable. When determining compatibility between a crimp/clamp and tubing, refer to the product specifications to be sure they adhere to the same ASTM standards and SDR (typically SDR-9)
