What Is PEX Tubing

PEX tubing is a flexible plastic pipe used in plumbing and heating systems. It is made from cross-linked polyethylene. This material resists scaling, corrosion, and freezing. PEX is used for both hot and cold water delivery. It is also suitable for underfloor heating and snow melting systems. The tubing is color-coded-typically red for hot and blue for cold. PEX is lightweight and easy to handle. It bends around corners without fittings, reducing labor time. The flexibility of PEX makes it easier to install than rigid copper or PVC piping.
