Description
–
Rifeng, the largest manufacturer of plastic piping in the world, has created oxygen barrier PEX tubing for radiant and hydronic heating systems. Oxygen barrier PEX tubing has the same properties as non-barrier PEX pipes, but it prevents oxygen and other elements from infiltrating and damaging delicate heating system components. For example, it keeps boilers from rusting. Rifeng PEX pipe is made of polyethelene which is cross-linked to enhance performance and maintain the properties of thermoplastics. Furthermore, this tubing can be installed in a variety of ways, such as using the crimp, clamp, or fitting systems. Rifeng offers a 25-year warranty on the product.

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: WE ARE POURING A RADIANT HEAT SUB FLOOR AND I HAVE BEEN TOLD NOT TO RUN TUBING UNDER WHERE THE CABNETS AND APPLIANCES WILL BE, OR NEAR THE TOILET. ALSO HAVE BEEN TOLD TO STAY 6" AWAY FROM THE WALL.DO YOU ALSO RECOMMEND THESE GUILD LINES FOR LAYING THE TUBING?OR HAVE ANY OTHER BIG RULES FOR LAYING THE TUBING?
Asked by jenett 15 years ago
Add your answer
Verified Reply- PexSupply StaffWe would agree with keeping 6" off the wall. You could place tubing under the cabinets and appliances if you want to, however, it is not necessary and will save you some dollars on tubing by using less. You will want to be about 6-8" away from your wax toilet ring.

Q: how can I straighten short pieces of pex and is heat bad for o2 barrier
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffThe warmer tubing gets, the easier it is to bend. You may want to use a heat gun to help straighten it out. The heat will not affect the oxygen barrier.
