PEX piping was introduced in the US in the 1980s and is gaining rapid growth in terms of demand for production.

The color-coded pipes facilitate easy installation as they identifies hot (red pipe) and cold (blue pipe) water. Plumbing fixtures can be easily done as PEX plumbing can be connected through mechanical fittings. Standard approved mechanical fittings for PEX are as follows, ASTM F 1807and ASTM F 1960. These are both reference mechanical fittings. The crimp fitting specified in ASTM F 1807 is the most accepted. Other fittings systems including outside diameter compression fittings are also available. However, PEX cannot be joined by solvent cement or heat fusion methods. PEX products cannot be used on aboveground water applications. It can only be exposed to sunlight for limited periods of time during installation but it should not exceed the allowable time recommended by the manufacturer. PEX products should be covered and protected from direct sunlight.
