What is “PEX” tubing?
It is a type of piping used for domestic water piping and hot water heating systems. PEX is a cross-linked polyethylene material. It is flexible, making it easy to install and service. PEX is able to withstand the high and low temperatures found in plumbing and heating applications, and is highly resistant to chemicals found in the plumbing environment. Flexible piping is quieter than rigid piping. The smooth interior will not corrode like galvanized piping will. PEX is also very freeze-break resistant. PEX systems have fewer joints and are easier to install providing a lower cost installation over traditional plumbing materials.
