SharkBite PEX tubing is a cross-linked polyethylene tubing for a wide range of residential and commercial plumbing applications. Manufactured with an oxygen barrier for radiant floor and hydronic heating applications (available in orange). The oxygen diffusion barrier applied to the exterior limits oxygen permeation through the tubing wall in hydronic heating applications which prevents corrosion of ferrous metal parts in the heating system. repeating SharkBite imprint pattern provides a visual aid to determine if the tube has been inserted all the way into the SharkBite Push-Fit Fitting. This feature only works if the tubing is cut between the SharkBite imprint pattern.

Can your Oxygen Barrier Pex be used for potable water? Previous answers have been ambiguous in my view. Thanks.

Asked by: PaulR
Good morning PaulR, You are correct. In reaching out to our Product manager, Oxygen Barrier PEX is not NSF 61 certified or is not listed as Potable water. The previous information provided was incorrect. I apologize for any inconvenience may cause. If you need to return this or ship new product to you and will be experiencing issues, I'd like to make it up to you and see what I can do to help make it an easy transition. Please contact me directly at techsupport@cashacme.com. Again, I apologize for this mistake and will do what I need to in order to correct it.

Does this meet NSF Std 14 and 61 for potable water applications? I'm looking for options to install an open radiant heating system with potential to change to a closed system later.

Asked by: Conrad
Greetings Conrad, Our pipe meets NSF requirements. If you are going to use this on radiant heating, you should not be drinking from that system thus, the pipe does not have to meet that requirement.

I have hot water baseboard. Can I cut copper pipe and connect with Orange PEX and place Hyrodnic Kick toe heater? The out pipe of hydronic heater will be connected to Orange PEX and will go under floor to connect with other end of copper pipe. Is this OK?

Asked by: ISAM
Greetings Isam, As long as the system runs at our certified temperature/pressure, there shouldn't be any issues with this. You can go to this link and page 11 to view our PEX tubing specifications: http://www.sharkbite.com/sharkbite/wp-content/uploads/2013/06/SHARKBITE-PEX-INSTALLATION-INSTRUCTIONS.pdf

"We are adding hydronic radiant heat to another room in our house.  We have always soldered our copper pipes and then attached it to the 1/2" pex tubing in the floors with barb brass fittings & crimp rings. Can we use SharkBite push fittings safely?

Asked by: Terry
Greetings Terry, SharkBite push-to-connect fittings are certified up to 200 degrees Fahrenheit with water or up to 100% glycol solution. There is no issue using them with hydronic systems.
