Mueller Streamline COADFTGMIP112 Copper Male Adapter 1-1/2 in

Product Description

The MUELLER STREAMLINE COADFTGMIP112 is a 1-1/2 inch copper male adapter fitting designed to transition between copper tubing and threaded pipe connections. The fitting features a solder-cup (Ftg) end that joins directly to copper tube and a male iron pipe (MIP) threaded end that connects to female-threaded fittings, valves, or equipment ports. It is a standard component in residential and commercial plumbing systems where a copper run terminates at a threaded connection point. Licensed plumbers and pipefitters are the typical installers for this type of transition fitting.

This adapter is used in domestic water supply systems, hydronic heating lines, and general plumbing rough-in work wherever a copper distribution line needs to tie into a threaded iron pipe or brass valve. The 1-1/2 inch size suits main supply lines, drain connections, and branch feeds in both residential and light commercial applications. It is appropriate for above-ground and in-wall installations where copper is the primary piping material.

Key Features

• Solder-cup (Ftg) inlet end accepts copper tubing for a reliable sweat-soldered joint
• Male iron pipe (MIP) threaded outlet connects to standard female NPT fittings and valves
• 1-1/2 inch nominal size suits main supply and branch line applications
• Copper construction provides corrosion resistance in potable water and hydronic systems

Compatibility

Designed as an OEM-style replacement and standard-service fitting for 1-1/2 inch copper plumbing systems requiring a transition to female NPT-threaded connections.

Installation Notes

Installation is performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the water supply and fully depressurize and drain the line before soldering. Clean and flux both the copper tube and the solder-cup end thoroughly before applying heat to ensure a leak-free joint. Apply thread sealant tape or paste to the MIP threads before making the threaded connection; do not overtighten, as copper threads can be damaged by excessive torque.
