Push Fit (Sharkbite)
Rifeng PEX pipe is produced with crosslinked polyethylene. Crosslinking is obtained through a chemical process that increases the bonds between macromolecules to form a more complex structure than the normal polyethylene. Due to the crosslinking, the polyethylene's performance is greatly enhanced and maintains the excellent properties of thermoplastics. Offering excellent corrosion resistance, incredible flexibility and unusual toughness, Rifeng PEX pipe allows for fast and easy installation.

Comments about 3/8" Blue PEX Tubing (500 ft Coil):
I order a 100 feet of this tubing about six months ago. It was used to cover 5/16" rod divders on a harp rack. The harp rack used to transport Insulated Glass Units( the double pane glass in windows) It has done pretty well against the sharp edges of the glass. That is why I order the additional 1500 feet to commplete the recovering of 6 harp racks

Q:what is the rating for air pressure
A:they arent rated that way. but Rifeng pex is rated to 180PSI
Q:Does the Rifeng or Bulldog PEX carry the NSF 61 Listing for potable water ?
A:Yes, This Rifeng tubing is approved for use with potable water systems.
Q:how does it handle sunlight (UV)
A:PEX tubing should not be installed or left in a location with UV light for extended periods of time. The light will degrade and damage the PEX leaving it brittle and subject to failure.
Q:We have a cabin in the mountains that we close up for the winter due to the snow. Can this tubing withstand freezing temperatures without bursting or cracking?
A:Since it has some flexibility, PEX tubing has better freeze resistance than rigid pipe (copper, etc.). PEX can still burst, however, if water freezes inside of it. Although there is some extra leeway with PEX, we would never recommend allowing water to freeze in the lines. You should drain the system during the winter months.
Q:Max pressure rating at temps? Not listed on any sizes I have checked.
A:Rifeng lists 160psi at 73F and and 100psi at 180F.
Q:I want to run a new PEX water line for an RO unit and intend to run in a concealed space. Is this safe for the concealed locations (run thur the framing behind the sheetrock and under the floor as well). I don't want to use copper.
A:PEX tubing is safe for installation in concealed locations and under floors. It can also be buried outdoors. PEX is not rated for UV exposure, so it should never be installed in areas exposed to direct sunlight.
