Midland Industries 77334 1 in C X 1 in Mpt Copper Adapter

Product Description

The MIDLAND INDUSTRIES 77334 is a wrot copper male pipe adapter designed to transition a 1-inch copper sweat (C) connection to a 1-inch male pipe thread (MPT). Wrot copper construction delivers reliable corrosion resistance and a pressure rating of 500 psi with a service temperature range of 32 to 200 degrees F. This fitting is used to join copper tubing systems to threaded pipe components in potable water, hydronic heating, and general plumbing distribution lines. Licensed plumbers and pipefitters install this adapter as part of copper sweat assemblies wherever a threaded male connection is required at a 1-inch transition point.

This adapter is suited for residential and light commercial plumbing applications. It is commonly installed in water supply lines, domestic hot and cold distribution systems, and hydronic heating piping where copper tubing must connect to a threaded fitting, valve, or equipment port. The C-end is soldered to standard 1-inch copper tubing, while the MPT end threads into a female-threaded fitting or equipment connection.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off and depressurize the water supply before soldering or threading any connections. The sweat end requires proper flux application and lead-free solder per applicable codes before joining to copper tubing. Apply thread sealant tape or compound to the MPT threads before making the threaded connection; do not overtighten.
