The PEX tube is intended for hot and cold potable water distribution systems. The tube can withstand a maximum heat temperature of 200 degrees Fahrenheit for applications for heating. In a plumbing project, the PEX is able to stand a maximum heat of up to 180 degrees Fahrenheit.
Several different materials are available for use, one of which is PEX piping. Developed for use in Europe during the 1970s, PEX piping was first introduced to the United States in 1980. PEX stands for crosslinked polyethylene, meaning the tubing is resistant to the adverse effects of hot and cold temperatures. The crosslinking occurs through a chemical reaction between the polyethylene within the piping, the result of which is a flexible, resistant tubing.
