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.

Does the OXYGEN BARRIER PEX TUBING (3/4") have to be installed in non-light conditions - within flooring as opposed to being laid around the perimeter of a room interior?

Asked by: portfish
Good morning, All PEX should not come in direct sunlight. As long as you make sure it doesn't do that, you'll be okay to install it anywhere else.

would you approximate the degree of flow restriction created by using 3/4"" shark-bite couplings (say two in a 30-foot run), as opposed to using a continuous PEX tubing for a radiant heat application?

Asked by: portfish
Good morning, The amount of flow "loss" using any of our fittings would be in the 2 to 3 decimal range. You don't see a drop off until upwards of 6 to 7 gpm and still that would be closer to 1 or 2 decimal range.

Do you have radius forms to tie to 3/4" Orange PEX. We are going to use your 3/4" tubing to form cooling loops in precast concrete bridge pier columns. We want prefabricated form to plastic-tie to the tubing to prevent kinking during the concrete pour?

can this pipe be expanded like normal pex pipe

Asked by: belfast
No, the expandable PEX is a different kind than what SharkBite manufactures. Expandable PEX is referred to ask PEX A. We manufacture PEX B, which is the red, white and blue PEX, and PEX C, which is the orange PEX you have here. They cannot be expanded.

Do you have a tubing that is UV resistant and will stand up to extended outdoor exposure?

Asked by: JohnF
Good afternoon, Our tubing can withstand being exposed to UV for up to 30 days before you should have it completely covered or buried.

Does the orange pex squeak a lot if used as supply lines for cast iron radiators.  I just installed and as it is currently tacked to floor joists it is squeaky a lot when moved..  As is expands with heat I am affraid it will make lots of noise...  

Asked by: MikeLa
Good morning, We have not heard of our PEX pipe squeaking after installation. If you are getting squeaking, the support on the pipe may be too tight.

Can the oxygen barrier tubing & black plastic fittings be used for a cast iron hot water radiator system?

Asked by: steve816
As long as the systems does not exceed 200 degrees F or 200 psi you should be good to go.
