Mueller Streamline COADFTGFIP1 Copper Female Adapter 1 in

Product Description

The MUELLER STREAMLINE COADFTGFIP1 is a 1-inch copper female adapter fitting configured with a solder-cup (Ftg) inlet and a female iron pipe (FIP) threaded outlet. This fitting transitions a copper sweat connection to an internal female NPT thread, allowing a copper line to terminate at a threaded connection point. It is a standard-stock fitting used in residential and light commercial plumbing systems. Licensed plumbers and pipefitters install this type of adapter when connecting copper supply lines to threaded valves, fixtures, or equipment stubs.

This adapter is suited for potable water supply lines, hydronic heating piping, and general plumbing rough-in work where a copper-to-threaded transition is required at a 1-inch nominal pipe size. Typical applications include connecting copper main lines to ball valves, pressure-reducing valves, water heaters, and other threaded plumbing components. It is appropriate for both new construction and retrofit installations where a clean, leak-free copper-to-NPT joint is needed.

Key Features

• 1-inch nominal size fits standard 1-inch copper tube OD for solder connection
• Ftg (fitting) end accepts copper pipe or tube directly for sweat soldering
• FIP threaded outlet accepts male NPT threaded fittings, valves, and fixture shanks
• Copper construction provides corrosion resistance in potable water and hydronic systems
• Standard adapter geometry allows installation in tight spaces with minimal offset

Compatibility

Designed as an OEM-style copper sweat fitting compatible with standard 1-inch nominal copper tubing systems using NPT-threaded components per ASME B16.18 or B16.22 dimensional standards.

Installation Notes

Installation should be performed by a licensed plumber in accordance with the applicable International Plumbing Code (IPC) or local authority having jurisdiction. Shut off and drain the water supply completely before soldering; residual moisture will prevent a proper solder joint. Use lead-free solder and flux rated for potable water service where required by code. Apply thread sealant tape or compound rated for water service to the male NPT threads before making up the threaded connection.
