Sharkbite U518LFA4 3/4 Inch End Stop Push-to-connect 4 Pack

Product Description

The SharkBite U518LFA4 is a 3/4-inch push-to-connect end stop sold in a 4-pack, designed to permanently cap off copper, CPVC, or PEX pipe in any combination without soldering, clamps, unions, or glue. Installation requires no special tools for the initial connection — insert the pipe and internal stainless steel teeth grip the pipe wall while a specially formulated O-ring compresses to form a watertight seal. The fitting can be rotated after assembly, which simplifies work in tight or confined spaces. Licensed plumbers and pipefitters use this fitting for both new construction and repair applications on potable water supply and hydronic heating systems.

This end stop is suited for residential and light commercial plumbing where a quick, reliable pipe termination is needed. It accepts copper, CPVC, and PEX pipe at 3/4 inch, making it a flexible solution when mixed pipe materials are present in the same system. The 4-pack format supports service calls that require capping multiple lines in a single visit. It is certified for use on potable water supply lines and hydronic heating applications.

Installation Notes

Installation is performed by a licensed plumber. Shut off the water supply and relieve system pressure before fitting installation. Ensure pipe ends are cut cleanly and deburred before insertion to allow the O-ring and stainless steel teeth to seat properly. A SharkBite disconnect tool can be used to remove and reuse the fitting if system changes are required after assembly.
