Homewerks 511-46-1-1B 1 Inch Pvc Compression Mpt Adapter

Product Description

The HOMEWERKS WORLDWIDE LLC 511-46-1-1B is a 1-inch PVC compression male pipe thread (MPT) adapter designed for cold water plumbing applications. It connects compression-style fittings to male-threaded pipe ends using included nuts and rubber gaskets, creating a secure, leak-resistant joint without solvent cement. Rated at 150 psi at 73 degrees F, this adapter is suitable for use on galvanized or plastic pipe. Licensed plumbers and experienced DIYers install this fitting during water supply line repairs, extensions, or conversions where thread-to-compression transitions are required.

This adapter is intended for cold water service on galvanized steel or plastic piping systems in residential and light commercial plumbing. It is a practical solution for transitioning between threaded pipe ends and compression-style tubing runs, particularly in tight spaces where soldering or cementing is not practical. The included rubber gasket provides a positive seal without additional sealant tape in low-pressure cold water lines, though thread sealant is still recommended by most plumbers for threaded connections.

Compatibility

Designed for use in cold water applications on galvanized or plastic pipe. Suitable for residential and light commercial plumbing systems requiring a compression-to-male pipe thread transition on 1-inch pipe.

Installation Notes

Installation of this adapter is typically performed by a licensed plumber or qualified tradesperson. Shut off the water supply and relieve line pressure before beginning work. Ensure mating pipe ends are clean, deburred, and properly sized before tightening compression nuts. Apply thread sealant or PTFE tape to all threaded connections per IPC guidelines and do not overtighten, which can crack PVC fittings.
