Decent pex tubing
Most Liked Negative Review
More brittle and difficult to handle than other pex I used
Has worked good for me. No complaints.
Not all Pex-b is the same
was easy to install in extrusions
SQUEAKY!! And difficult to work with
For the price it's worth it
Best price in the USA
Good price
O2 pex B
Good value
I would buy again and recommend to all friends

102 QuestionsQ: What is the bend radius for 3/4 pex?
Asked by Darren 14 years ago
Add your answer
Verified Reply- PexSupply Staff3/4" PEX has a 5.25" bend radius.
Minimum radius is six times the diameter. Just be careful not to kink it. There are special elbow brackets to support a tight radius. They are made to bring tube out of a floor and into a wall or where ever a tight 90 is needed. If running 3/4 in a floor, most installers will use an "hour glass" 180 to give the pex a larger radius for a 180 turn-a-round and then keep a 9" spacing on the parallels if that is what the design calls for. You seldom will see 3/4 spaced this close unless it is for a snowmelt system. Sent on the Sprint® Now Network from my BlackBerry®
depending on the brand of pex you get, between 5 and 8 inches minimum (radius) scott
I did not bend the 3/4 pex I got but I would think if you heat it somewhat you would be able to bend it in a 18 inch radius.
I have not bent the 3/4" but the 5/8" easily bends to form a 12" loop for radiant heat so I suppose the bend radius is 6" or less. I wouldn't push the 5/8" any more than that.
Q: What type of hangers do you recommend for hanging this right underneath floor joists?

Verified Reply- PexSupply StaffWe'd recommend the Viega clips (part 58074).
Q: can us use a spray foam insulation on oxygen barrier PEX Tubing?
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffYou can, as long as the insulation does not contain any adhesives.
Q: How is the quality of drinking water from this type of plumbing versus copper/pvc?
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffThe materials in PEX tubing are chemically inert. They do not react with or contaminate water. Neither will fittings: all PEX fittings are mechanical, and do not use glues, chemicals, adhesives, or cements. Oxygen barrier PEX, however, is not approved for use with potable water (it is designed for closed-loop heating systems). In plumbing applications, always use non-oxygen barrier PEX.
Q: I am building a barn and would like to add radiant floor to a 20'x20' area. Can I tie the PEX directly to the rebar and will this deteriorate its life span due to vibration with the rebar.
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffPEX can be attached directly to rebar. Its lifespan will not decrease as a result.
Q: I built a 40' x 72' post frame building a year & a half ago & had radiant heat put in the 6" concrete floor. I used the Rifeng oxygen barrier PEX & my question is about this product's UV resistance. There's about 14 PEX lines coming out of the floor into the manifolds which are approx. 15" long & have been exposed to indirect sunlight for the last year & a half. I wasn't originally aware that UV & PEX don't mix but plan to immediately build a box around the exposed lines. My question is whether or not I can do anything else to condition or lengthen the life of the lines that have seen sunlight. They currently function & look good. Is there anything I can look for (other than leaks) to determine whether or not they have suffered any damage due to the exposure? Thanks.

Verified Reply- PexSupply StaffIf the UV were to affect the PEX, it would become rigid and brittle.
Cover Pex exposed to the sunlight with split foam pipe insulation. I like the self adhesive type, so it glues itself (seam) together. The split foam is usually in 6 foot sticks (lengths). What happens is that the Sun's UV rays un-links the cross links (that is what the X in PEX means). Pex ( cross linking of the Poly Ethylene) is manufactured in 3 ways, one of which is to cross link the molecules with Ultra Violet rays, thus the un-linking with UV.
Q: Does this oxygen barrier pex work with Sharkbite brand fittings>
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffYes, this tubing is compatible with SharkBite fittings (in addition to crimp, clamp, compression, and PEX press fittings).
Yes, it does.
3/4 Oxygen Barrier PEX Tubing is compatible with Sharkbite brand fittings.
I have used sharkbite fittings with this and it works fine, just really hard to take the fitting off, with the tool.
Q: What is the maximum temperature Oxygen Barrier PEX tubing is rated for?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffIt is rated up to 200°F at 80 psi.
180 deg?
Q: Will this work for a pressureized boiler system with part of it buried underground and insulated?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffYes, as long you don't exceed the pressure rating of the tubing (80 psi at 200°F, 100 psi at 180°F, 130 psi at 120°F, and 160 psi at 73°F).
Q: I can not find the 90 elbow to connect this tubing to slant fin baseboard ..there should be 2 different elbows one with a street fitting and one with a t for pressure relief. Both copper to pex 3/4-3/4 . Am i correct and do u have it

Verified Reply- PexSupply StaffWe do not have a baseboard tee for PEX tubing. We do have PEX baseboard elbows manufactured by Rifeng.
