Decent pex tubing
Tubing is nicely priced and was a little hard to uncoil/unroll, more rigid and popped out of tracking sometimes but with three people it was easy to finish the job.Also found out that this style tubing doesn't have a friction barrier built in so it does make some noise when heating up and cooling off when strapping it down with the Uponor 1/2" pex rails. I was told when the mud floor gets laid down the expansion/contraction noises will not be heard.The company manufacture changed its name from Rifring to Bluefin for guys who like to do research,I don't know why? I would recommend this product BUT If I had to do it again I would tell someone the pro and cons and probably would have invested in a few more $$ into uponor's al-a-pex tubing because it was easier to work with when I did previous work to my radiant heating system

More brittle and difficult to handle than other pex I used
I bought 2000 feet of Mr. Pex 1/2" and 300 feet of this stuff ( by mistake ). When I ran out of Mr. Pex, I switched to this, and using it was much more difficult. It feels thinner, holds its coiled shape more, making it more difficult to lay out, and the ratchet cutter didn't really smoothly cut through, they seemed to apply pressure and eventually snap. In the end, it did its job and passed a pressure test no problem, but I was glad I only had to use it for one loop.

Not all Pex-b is the same
I've used 100' and 300' rolls of 1/2 Pex-b from big box stores and I can say the Supply House Bluefin has superior surface finish quality. Box store material is dull and matte which is often very hard to pull through walls and other areas we install radiant heat lines. Bluefin has a gloss finish surface and it pulls like a dream, even for Pex-b

was easy to install in extrusions
It is numbered every 5' from 1000' on down, making it easy to keep track of loop lengths. Water was coming out if it so I can presume they did a wet pressure test on the tubing.

SQUEAKY!! And difficult to work with
I installed this tubing, used it for 1 week, and then replaced it all. Thermal expansion/contraction causes "tick, tick, tick" noises during temp changes at seemingly every point of contact with other materials, especially wood.
I needed to pass these lines through floor joists, and the noise was so annoying on both floors. Unacceptable.
It's also very stiff, doesn't bend easily, and the same sticky outside that causes the expansion noises makes it very difficult to pull through multiple joist holes, especially if they are misaligned at all. Do yourself a favor and buy Uponor hePEX. Yes, it's 3x the cost. Yes, it's worth that.

For the price it's worth it
This product does the job, although I find it's slightly more stiffer than other PEX B or C brands than are in my local stores (one heck of a lot stiffer than PEX A). After doing over 7,000 ft of this pipe…man, the stiffness gets annoying, but then I look back at the price and say it ain't so bad. There is laser printing on the pipe every few feet that tells you how much pipe you have left and just going off that unit of measurement each coil ends up having 15ish extra feet beyond the 1,000 ft mark. None of the coils had any defects, although there were a couple that had some rubbing marks within 1 feet of the end, but since each coil had an additional 15' this wasn't an issue. All in all, I'd buy this again mainly for the price and due to the really fast shipping speed from Supply House (2 days in my case)

Best price in the USA
Using this Pex for radiant heat in a slab and found Bluefin to be the best price in the entire USA! This is PEX-B so it's way less flexible than A and is a bit harder to manage bends and such. I contemplated going with 5/8, but after messing around with 1/2 I'm glad I stuck with 1/2…I think the 5/8 would have been too much effort to bend and straighten out. The only con was that the roll did not have and feet measurement on it, so you have to be aware of your length as you go.

O2 pex B
The only thing that would make it better, is if it straightened itself out. Decent price, great shipping time in my location.

Good value
This roll of oxygen barrier pex is a good value for subfloor radiant heat. I am able to install it within joists 16" oc. using crimp rings where needed. Trying to find it locally is difficult. Supply House UPS shipping was fast and free with orders over $100.

Q: I am doing baseboard hot water heat and will use pex pipe. I have two runs of pipe that will be in the concrete to go under a sliding door (7') and my kitchen (18'). The intent of those runs is not to heat from the slab, but rather get from point A to point B. I planned to wrap the pex in the foam pipe insulation for those concrete runs. Can I excede the 150 degree temp max and be more like 190 in this special case?

Q: I will be using 3/4" Oxygen Barrier Pex Tubing for my radiant heat. My boiler is set at 190 degree F. My question is will the o2 pex hold up to that heat. I will be hooking up to baseboard radiators. My other question is for my radiator hook up. Is it ok if I use a sharkbite adapter with 3/4 male thread and hook 3/4 female threaded to it with pex male on the end of that? will the sharkbite hold up to 190 degrees?

Q: What is the recommended maximum run before significant heat loss occurs? It will be running less than 200ft and under wood.
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe maximum run we would recommend is 300 feet. The heat loss of the piping is directly related to the circulator you are using.

Asked by ethel 15 years ago

Verified Reply- PexSupply StaffThis Rifeng tubing should be fine for you. If you are using an expander tool, you will need to use PEX-A tubing (HePEX or ThermaPEX).

Q: Is it true that I should stay under 300' per loop? If so why? Also should all zone loops be the exact same length?
Asked by ethel 15 years ago
Add your answer
Verified Reply- PexSupply StaffYou should try to stay under 300' per loop because most pumps would not be able to handle the flow rates necessary at longer distances. It is best to try to create zone loops that are the same length, but manifolds with balancing valves exist because it can be difficult to accomplish this.

Q: I plan on using 1/2 in pex for an under floor radiant application. Of the two , is pex a or is pex b easier to handle , or more flexable ? Does one allow a tighter radius ?
Asked by jeff 15 years ago
Add your answer
Verified Reply- PexSupply StaffPEX-A is a little bit easier to handle, but it is not really more flexible and does not allow a tighter radius. Basically, you can do the same things with both grades, but it may require less effort with PEX-A tubing.
