Mueller Streamline COADCFIPRED3412 Copper Reducing Adapter

Product Description

The MUELLER STREAMLINE COADCFIPRED3412 is a copper female reducing adapter configured in a C x FIP end pattern, transitioning a 3/4 inch copper sweat connection to a 1/2 inch female iron pipe threaded port. This fitting is used to reduce pipe size within a water supply or distribution system while converting from a soldered copper joint to an NPT threaded female connection. Plumbers and pipefitters install this adapter where a copper run must connect to a threaded valve, fixture, or fitting of a smaller diameter. The all-copper construction provides corrosion resistance and reliable long-term performance in potable water and hydronic applications.

This reducing adapter suits residential and light commercial plumbing installations where copper tubing meets threaded iron pipe components. Common scenarios include connecting copper supply lines to threaded shutoff valves, fixture supply stops, or threaded manifold ports. The C x FIP configuration means the 3/4 inch end is soldered directly onto copper tubing while the 1/2 inch end accepts a male NPT threaded fitting. It is appropriate for use in both new construction and retrofit or repair work.

Key Features

• Reduces from 3/4 inch copper sweat inlet to 1/2 inch female NPT outlet in a single fitting
• C x FIP end pattern allows direct solder connection on one end and threaded assembly on the other
• Copper construction resists corrosion in potable water and hydronic piping systems
• Compact adapter profile minimizes space requirements in tight plumbing rough-ins
• Compatible with standard NPT threaded male fittings on the 1/2 inch FIP end

Compatibility

Designed as an OEM-style replacement and standard trade fitting for copper water supply and distribution piping systems using 3/4 inch sweat connections transitioning to 1/2 inch female iron pipe thread.

Installation Notes

Installation is performed by licensed plumbers following applicable IPC and local plumbing code requirements. Shut off the water supply and depressurize the line before cutting or soldering. The copper sweat end requires proper flux application and lead-free solder per code; the FIP threaded end should be assembled with appropriate thread sealant tape or compound rated for potable water service. Do not overtighten the threaded connection, as copper threads can be damaged by excessive torque.
