Midland Industries 77341 Copper Adapter 3/8 C X 1/2 Fpt

Product Description

The MIDLAND INDUSTRIES 77341 is a wrot copper female pipe adapter designed to transition between a 3/8-inch copper sweat (C) connection and a 1/2-inch female pipe thread (FPT) connection. Wrot copper construction provides reliable corrosion resistance and durability in pressure-rated plumbing applications. Rated to 500 psi and suitable for service temperatures from 32 to 200 degrees F, this adapter handles the demands of residential and light commercial water supply lines. Licensed plumbers and HVAC technicians install this fitting when connecting copper tubing runs to threaded pipe fittings, valves, or equipment ports.

This adapter fits common plumbing applications where copper sweat lines terminate at a threaded valve, fixture supply, or equipment connection point. It is used in residential water distribution, hydronic heating systems, and HVAC refrigerant-adjacent piping where copper-to-female-thread transitions are required. The compact profile fits in tight spaces typical of equipment closets and mechanical rooms. Its standard sizing makes it a go-to fitting for service and repair work across residential and light commercial jobs.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician. Shut off and depressurize the water or fluid supply line before beginning work. The sweat end requires proper flux application and soldering per applicable plumbing codes, including IPC guidelines. Apply thread sealant or PTFE tape to the FPT connection before threading onto the mating fitting to ensure a leak-free joint.
