Hey it's Mark from PexSupply.com and this is Rifeng oxygen barrier PEX tubing.
This PEX-b grade tubing is designed for use in closed-loop hydronic heating systems. It is a high quality and reliable tubing, though slightly less flexible than PEX-a tubing due to the manufacturing process used for its production.
The oxygen barrier prevents oxygen from the air from penetrating the hydronic heating system and rusting cast iron system components.
It comes in sizes ranging from 3/8" to 1" and works with crimp, clamp, compression, PEX press, and SharkBite PEX connections. ProPEX expansion connections do not work with this or any other PEX-b tubing.
This tubing has a maximum temperature rating of 180 degrees F up to a pressure of 100 psi. It can handle a maximum pressure of 160 psi up to a temperature of 73 degrees F. Rifeng tubing is backed by a 25-year manufacturer's warranty.
