3517-14 Pex Quick Connect Pipe Elbow, 3/4 In.

The Watts 3517-14 is a quick connect elbow fitting for PEX, copper, CPVC, and polybutylene tubing designed for fast, tool-free installation. Whether you're installing new plumbing or repairing an existing system, this elbow eliminates the need for soldering, crimping, or special tools. Simply cut your pipe, push the tubing into the fitting end until it seats at the stop, and you have a secure connection rated for 250 psi. Disconnection is equally simple—just pull back the release ring and remove the pipe.

This fitting is ideal for homeowners and professionals tackling water supply projects in both hot and cold applications. The fitting is reusable and can be disconnected by pulling back on the ring, allowing you to adjust connections during plumbing work and repairs. Because this fitting rotates under pressure, you can adjust tube orientation even after installation, giving you greater flexibility when working with multiple tubing materials.
