The RELIANCE WORLDWIDE UXL0435 is a 1-1/4-inch end cap designed to terminate or seal the open end of a pipe, tube, or fitting run. End caps are used to close off a line that is no longer in service, capped during a staged installation, or requires a pressure-tight seal at a system terminus. This fitting is a compact, low-profile component that plumbers and pipefitters encounter on routine residential and light commercial jobs. At 0.44 pounds, it is a lightweight part suited for quick installation without specialized tooling.
This end cap is intended for use in plumbing systems where a 1-1/4-inch pipe termination is required. Common applications include domestic water supply lines, drain-waste-vent rough-ins, and hydronic piping where a branch or stub-out must be closed off. It is well suited to residential service calls and new construction plumbing roughing stages where installers need a reliable, code-acceptable cap fitting.
Designed as an OEM-style end cap for 1-1/4-inch pipe fittings, consistent with the SB2XL fitting series. For specific system or model compatibility, consult RELIANCE WORLDWIDE documentation or your local code authority.
Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing code requirements. Before installing or removing any fitting, shut off the water supply and relieve system pressure completely. Use the appropriate joining method for the pipe material in use, and inspect the mating surface for debris or damage before seating the cap. Pressure-test the assembly after installation to confirm a leak-free seal.
