Midland Industries 77353 Copper Adapter 3/4 C X 1 Fpt

Product Description

The MIDLAND INDUSTRIES 77353 is a wrot copper female pipe adapter designed to transition between a 3/4-inch copper sweat (C) connection and a 1-inch female pipe thread (FPT). It is rated to 500 psi and handles temperatures from 32 to 200 degrees F, making it suitable for domestic water supply, hydronic heating, and general plumbing distribution systems. The wrot copper construction provides reliable joint integrity and is compatible with standard lead-free soldering procedures. Licensed plumbers and pipefitters install this fitting in both residential and light commercial applications where a threaded female port is needed at a copper branch or mainline.

This adapter is used where a copper sweat line must connect to a threaded iron, brass, or copper male pipe thread component. Typical scenarios include transitioning from a copper supply line to a threaded valve body, manifold, or fixture connection. It is appropriate for potable water, hydronic, and light commercial plumbing systems operating within its rated pressure and temperature range. With a minimum order quantity of one, it suits both single-unit service calls and larger installation jobs.
