PEX Tubing


PEX tubing WaterPEX® Tubing is suitable for use with hot or cold water. One advantage of PEX pipe tubing is its versatility. It can be used with steel, copper, PVC, and CPVC plumbing pipe. This tubing is the most flexible plumbing pipe available. This flexibility allows it to expand and contract more than another type of tubing, which makes PEX tubing burst-resistant. Fresh Water Systems offers some of the best PEX pipe fittings. We also have a range of PEX tubing tools, supplies, and connectors at an affordable cost.

What is PEX Tubing?

WaterPEX® Tubing is a silane cross-linked polyethylene material (B PEX) ideally suited for potable water applications. WaterPEX® is manufactured without an oxygen barrier and may be used in radiant heat applications where there are no ferrous (metal/iron) components.

WaterPEX® Tubing is also known as Sea Tech Pex Tubing and Aquapex® Tubing and is available in multiple colors for ease of water line identification. PEX is included in all of the major model plumbing codes used in the United States and Canada, CSA, IAPMO, SBCCI, BOCA, ICBO, IPC and NSPC, and approved by HUD for hot and cold potable water plumbing use.

How To Install PEX Pipe

PEX tubing installation and service is super easy. The tubing is flexible, so it can bend around most corners without a fitting or coupling. For example, 3/8" pipe may be bent to a 4" radius and 1/2" pipe to a 5" radius.

PEX Pipe Temperature Information

PEX's strength at temperatures ranging from below freezing up to 180 degrees Fahrenheit makes it an ideal piping material for hot and cold water plumbing systems, hydronic radiant heating systems, snow melting applications, and, even ice rinks and refrigeration warehouses. PEX is also highly resistant to chemicals found in the plumbing environment.
