Definition:
PEX is a type of domestic water supply and hydronic (hot water) piping used in radiant heat applications. PEX is made of cross-linked HDPE (high density polyethylene) polymer and has been in use since the 1970’s.
PEX is a type of domestic water supply and hydronic (hot water) piping used in radiant heat applications. PEX is made of cross-linked HDPE (high density polyethylene) polymer and has been in use since the 1970’s.
PEX is strong and flexible, withstanding temperatures from below 32 degrees to 200 degrees Fahrenheit. PEX is corrosion resistant and unlike copper pipe, will not develop pinholes. Because PEX uses fewer connections and fittings it is easier and faster to install. The reduced number of required fittings in a PEX system also reduces the possibility of leaks.
PEX piping is colored, typically blue (cold water) or red (hot water) or white flexible plastic pipe. It is cut and fit with specialized fittings and tools.
