Mueller Industries 15701 Copper Flush Bushing 1-1/4x1 Ftg X C

Product Description

The MUELLER INDUSTRIES 15701 is a wrot copper flush bushing used to reduce pipe size within a copper plumbing or HVAC piping system. It connects a 1-1/4 inches fitting-turn (FTG) end to a 1 inches cup (C) end, allowing a larger line to step down to a smaller diameter without adding significant profile to the joint. Wrot copper construction provides reliable pressure ratings and compatibility with standard copper soldering techniques. Licensed plumbers and HVAC technicians install this fitting during new construction, remodel, or repair work where inline size reductions are required.

This flush bushing is suited for residential and light commercial plumbing and refrigerant or hydronic piping applications where a concentric, low-profile reduction is needed inside an existing fitting or coupling. The FTG x C end configuration allows the bushing to insert directly into a fitting hub, keeping the assembly compact. It is packaged in a quantity of 2 units per package, making it practical for jobs requiring more than one reduction point.

Key Features

• Wrot copper construction for durability and compatibility with standard solder joining methods
• 1-1/4 inches FTG x 1 inches C end configuration for direct in-fitting installation
• Flush bushing profile keeps the reduction compact and low-profile within the assembly
• Outside diameter of 1-3/8 inches on the large end and 1-1/8 inches on the small end
• Packaged as 2 units per package

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard wrot copper piping systems using FTG x C end connections in 1-1/4 inches by 1 inches sizes.

Installation Notes

Installation is performed by a licensed plumber or HVAC technician using standard copper soldering tools and flux-core solder. Shut off water supply or isolate the refrigerant circuit and relieve system pressure before cutting into any existing line. Clean all mating surfaces with emery cloth and apply appropriate flux before soldering. Follow applicable local plumbing codes and ASTM standards for copper solder joint assembly.
