Midland Industries 77406 Copper Sweat Female Pipe Adapter

Product Description

The MIDLAND INDUSTRIES 77406 is a wrot copper female pipe adapter designed to transition from a copper sweat (C) connection to a female pipe thread (FPT) connection, both sized at 1-1/4 inches. Wrot copper construction delivers reliable strength and corrosion resistance in pressure piping systems. Rated to 400 psi and suitable for service temperatures ranging from 32 degrees F to 200 degrees F, this adapter is a standard fitting for plumbing and mechanical piping work. Licensed plumbers and pipefitters install this type of fitting during new construction and retrofit projects where a threaded female port is needed at the end of a copper run.

This adapter is suited for residential and light commercial plumbing systems, hydronic heating distribution lines, and general water supply piping. It is installed wherever a copper sweat line must terminate into a female-threaded connection, such as at valves, gauges, or equipment ports. The 1-1/4-inch sizing makes it a common choice for larger-diameter branch lines and main supply runs where flow capacity is a priority.

Key Features

• Wrot copper construction for high strength and corrosion resistance
• 1-1/4 in C x 1-1/4 in FPT transition - copper sweat to female pipe thread
• Pressure rating of 400 psi for demanding piping applications
• Temperature range of 32 degrees F to 200 degrees F
• Lightweight at 0.43 pounds for easy handling and installation

Compatibility

Designed as an OEM-style wrot copper female pipe adapter for use in standard 1-1/4-inch copper sweat piping systems requiring a female NPT termination point.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and applicable local codes. Shut off and drain the water supply before cutting into any existing line. The sweat end requires proper flux application and soldering with appropriate solder alloy; the FPT end should be assembled with an approved thread sealant or PTFE tape. Do not over-torque the threaded connection, as copper fittings can be damaged by excessive force.
