Reliance Worldwide 113532M Pex to Male Npt Adapter

Product Description

The RELIANCE WORLDWIDE 113532M is a push-to-connect PEX adapter that transitions a 1-1/4 inch PEX line to a 1-1/4 inch male NPT threaded fitting. It uses the SharkBite push-fit mechanism, which grips and seals the pipe without soldering, crimping, or special tooling. Plumbers and pipefitters install this fitting during new construction and retrofit work where a PEX supply line must connect to an NPT-threaded valve, fixture, or manifold port. The adapter is rated for use in potable water systems and is suitable for hot and cold water distribution lines.

This adapter is used in residential and light commercial plumbing applications where PEX tubing terminates at an NPT-threaded component. Typical install scenarios include water heater connections, shutoff valve transitions, and manifold hookups where the existing or new piping is PEX and the receiving port is male NPT threaded. The push-fit end accepts standard 1-1/4 inch PEX tubing, and the male NPT end threads directly into a female-threaded fitting or valve body.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters. Shut off and depressurize the water supply before making any connections. Ensure the PEX tube end is cut square and deburred before inserting into the push-fit collar. Apply thread sealant tape or compound to the male NPT threads before engaging the female-threaded receiving fitting, and follow local plumbing code requirements per the IPC or applicable jurisdiction.
