SharkBite PEX tubing is a cross-linked polyethylene tubing for a wide range of residential and commercial plumbing applications. This pipe is manufactured with an oxygen barrier for radiant floor and hydronic heating applications (only 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. A repeating SharkBite imprint pattern provides a visual aid to determine if the tube has been inserted all the way into the SharkBite Push-to-Connect Fitting. This feature only works if the tubing is cut between the SharkBite imprint pattern.

Rated 5 out of 5 by from Just what I needed at a great price I needed this to repair a radiator hookup in an older home. I had a hard time finding the 3/4" pex with oxygen barrier in any plumbing/heating supply store and ultimately tried Home Depot on line. I had it delivered to my home in about 4 days. Next time I'll try Home Depot first!

Rated 4 out of 5 by from Good product / easy to use. Used this product to make connections in existing hydronic heating system for additional baseboard heat. Used the clamp connections and some shark bite connections. You need the clamping tools for this. Can cut with a regular twist and spin pipe cutter but don't dig in too hard. Keep it warm as the colder it gets the hard it is to manipulate. Doesn't make 90 degree turns tightly, you need a good 12" -16" to make a 90. Just buy the 90 degree fittings if you don't have the space.

Rated 5 out of 5 by from Good product, easy to install Pex is a great product. Be aware that the pex clamps and tools are proprietary. Home depot has Apollo clamps and tools, which work very well.

Rated 4 out of 5 by from Excellent but beware Thie is some high quality PEX for heating application - but it is VERY STIFF - I had to use a blow dryer to get it to flex especially at 90 degree bends. Used with shark bite fitting to reroute a pipe the was running through my garage. So far working well. If you need PEX that's easy to bend try PEX-AL_PEX but I'm not sure where to get it.

Rated 5 out of 5 by from great product We bought this product to install hydronic heating in the floor of our new basement. Product exceeded our expectations, was easy to use, would definitely recommend to others and would purchase product again.

Rated 5 out of 5 by from PEX Radiant tube The 3/4" PEX is tough to make sharp bends; i.e. small radius, but managed to create a nice radiant tile floor from below underfloor, between joists.

Rated 5 out of 5 by from this was exactly what I was looking for. this tubing will replace the existing tubing that was wrongly installed.

Is there a maximum recommended length of run for 1/2" pex tubing ? What impact (equivalent of straight run) do 90 degree bends have on the run of pipe?

Asked by: SMCS
Good morning, There isn't a maximum run length. We make coils up to 500 feet long. You can find complete installation information by following this link: http://www.sharkbite.com/sharkbite/wp-content/uploads/2013/06/SB_PEX-INSTALLATION-INSTRUCTIONS.pdf

Is it ok to paint the pipe and not damage? All the pipes are exposed in my basement. I want to paint this orange pipe white to match others. Tks

Asked by: Hannah
Good afternoon, We wouldn't recommend painting it as it could dry out the tubing.

I have installed this replacing 3/4 copper pipe on my hydronic baseboard heat. I have noticed a very strong plastic smell in my basement. Also the piping appears to have lighted in color. My boiler temp kicks @ 165°-180° under 12lbs no more then 15lbs

Asked by: Tom860
Good morning, We have never heard about this kind of issue. If you can, please send photos to techsupport@cashacme.com so we can see the set up. This will allow us to work with our Product Managers and Engineers to see what might have caused this issue.

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.
