Mueller Streamline COADCFIP12 Copper Female Adapter

Product Description

The MUELLER STREAMLINE COADCFIP12 is a 1/2-inch copper female adapter fitting with a C x FIP (sweat by female iron pipe) configuration. It connects smooth copper tubing to female-threaded iron pipe fittings, creating a reliable transition between copper and threaded piping systems. Licensed plumbers and pipefitters install this type of adapter in residential and light commercial plumbing applications where a copper run must terminate or connect into a threaded fitting. The sweat end joins to copper tubing using standard soldering technique, while the FIP end accepts a male-threaded fitting.

This adapter is used in potable water supply lines, hot and cold distribution systems, and general plumbing rough-in work. It is suited for residential construction, remodel, and repair scenarios where a transition from copper pipe to a threaded connection is required. The 1/2-inch size is one of the most common nominal pipe sizes in residential water supply systems.

Key Features

• C x FIP configuration allows sweat-to-threaded transitions in copper piping systems
• 1/2-inch nominal size fits standard residential water supply lines
• Female iron pipe (FIP) end accepts standard male NPT threaded fittings
• Copper construction provides corrosion resistance and long service life in water systems
• Compatible with standard lead-free solder and flux per applicable plumbing codes

Compatibility

Designed as an OEM-style replacement and standard-use fitting for 1/2-inch copper sweat-to-threaded plumbing connections in residential and light commercial water supply systems.

Installation Notes

Installation is performed by a licensed plumber following local plumbing codes and ASTM B88 copper tubing standards. Shut off the water supply and depressurize and drain the line before soldering. Clean and flux all mating surfaces before applying heat, and use lead-free solder where required by code. Do not overtighten the FIP threaded connection; use appropriate thread sealant or tape per local code requirements.
