Abstract
Cross-linked polyethylene (PEX) tubing is utilized in a plumbing application for its strength and flexibility. A thin outer layer is formed around the PEX layer to provide a variety of color choices for the final tubing. The use of a softer material for the outer layer provides the unexpected benefit of a more secure connection as a standard connector having a ring is able to dig into the outer layer and provide a more secure grip and an improved hydraulic sealing.
