Reliance Worldwide U520LF End Stop 1 Inch Push-fit

Product Description

The RELIANCE WORLDWIDE U520LF is a 1-inch end stop fitting designed to cap off a water supply line quickly and securely using a push-fit connection style compatible with SharkBite-type fittings. This lead-free fitting allows technicians and plumbers to terminate copper, CPVC, or PEX pipe without soldering, gluing, or clamps. The push-fit mechanism provides a watertight seal in seconds, making it a practical choice for shutoff scenarios, system modifications, or temporary line terminations. At 0.3 pounds, the U520LF is a compact, low-profile fitting suited for tight spaces in residential and light commercial plumbing systems.

The U520LF is used in residential and light commercial plumbing applications where a supply line needs to be capped or terminated cleanly. Common install scenarios include capping unused branch lines, closing off supply runs during a remodel, or terminating a line that is being rerouted. Licensed plumbers and experienced pipefitters are the typical installers, though knowledgeable DIYers often work with push-fit fittings in low-pressure domestic water systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Always shut off the water supply and relieve system pressure before installing or removing any push-fit fitting. Ensure pipe ends are cut square, deburred, and clean before insertion to achieve a proper seal. Do not exceed the pressure and temperature ratings for the piping system when using push-fit connections.
