Midland Industries 77335 Copper Adapter 1-1/4 C X Mpt

Product Description

The MIDLAND INDUSTRIES 77335 is a wrot copper male pipe adapter designed to transition a copper sweat connection to a male pipe thread (MPT) fitting. Rated to 400 psi and suitable for service temperatures ranging from 32 degrees F to 200 degrees F, this adapter is built for reliable performance in plumbing and mechanical systems. The wrot copper construction provides superior strength and pressure integrity compared to cast fittings. Licensed plumbers and pipefitters install this type of adapter when connecting copper tubing runs to threaded pipe fittings, valves, or equipment inlets in residential and light commercial applications.

This adapter is used in copper sweat piping systems where a transition to male pipe thread is required. It is commonly installed at equipment connections, shutoff valve inlets, and service points in potable water, hydronic heating, and general plumbing distribution systems. The 1-1/4 inch sweat inlet accepts standard copper tubing soldered in place, while the 1-1/4 inch MPT outlet threads into a female-threaded fitting or port.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable IPC or local plumbing codes. Shut off and depressurize the system before soldering. Clean and flux the copper tube end thoroughly before sweat-soldering the fitting in place, and apply thread sealant or PTFE tape to the MPT threads before making up the threaded connection. Do not exceed the rated pressure or temperature limits of the fitting.
