SharkBite U518LF No-Lead Push-Fit End Stop, Brass

SharkBite U518LF No-Lead Push-Fit End Stop, Brass

The SharkBite U518LF is a push-fit end stop designed to cap and terminate a run of copper, CTS CPVC, or PEX tubing without soldering, clamps, unions, or glue. Available in 3/4" and 1" trade sizes, this brass fitting lets plumbers instantly close off a dead-end line during rough-in work. Insert the pipe end and the internal stainless steel teeth grip the tubing while an O-ring compresses to form a seal, capping the line for a clean, no-lead termination point behind the wall. Every size in this family is certified to 200 PSI and 200 degrees F (93 degrees C), making it a reliable choice for rough-in plumbing where a fast, tool-free stop is needed on any of the three common tube materials.

Why SharkBite?

SharkBite fittings use stainless steel teeth and a compression O-ring to deliver a dependable push-fit seal without soldering, clamps, unions, or glue, and the U518LF end stop carries that same no-lead, 200 PSI / 200 degrees F rated construction into a simple line-capping fitting available in 3/4" and 1" sizes. Because it can be disassembled with the standard disconnect tool and rotated after installation, plumbers get a fast, reusable solution for terminating copper, CPVC, or PEX runs in tight rough-in spaces.
