Mueller Industries 15682 Copper Flush Bushing 1x3/4 Ftg X C

Product Description

The MUELLER INDUSTRIES 15682 is a wrot copper flush bushing designed to reduce a 1-inch fitting connection down to a 3/4-inch copper tube connection. The end connection configuration is FTG x C, meaning the male end accepts a copper fitting socket on the larger side and connects to standard copper tubing on the smaller side. Wrot copper construction ensures consistent wall thickness, high pressure tolerance, and reliable soldering performance. This bushing is used by licensed plumbers and HVAC technicians to transition between fitting sizes within copper piping systems without adding significant length to the assembly.

This flush bushing fits into residential and light commercial plumbing and HVAC hydronic systems wherever a 1-inch to 3/4-inch reduction is needed at a fitting connection point. The flush profile keeps the transition compact and in-line, making it well-suited for tight spaces in mechanical rooms, under slab transitions, or within air handler piping assemblies. It is packaged in a quantity of 5 per pack, suitable for jobs requiring multiple reductions on the same system.

Key Features

• Wrot copper construction for consistent grain structure and strong solder joints
• Flush bushing profile minimizes added length in the piping run
• FTG x C end connection integrates directly into standard sweat copper fittings
• 1-inch x 3/4-inch size handles common residential and commercial pipe reduction scenarios
• Outside diameter of 1-1/8 inches x 7/8 inches for precise socket fit
• Packaged 5 units per pack to support multi-point installations

Compatibility

Designed as an OEM-style replacement and new-installation fitting for sweat copper piping systems using standard 1-inch and 3/4-inch copper tube and fitting dimensions.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians using standard sweat soldering techniques. Shut off and drain the water or fluid system completely before cutting into any existing piping. Clean all mating surfaces with emery cloth and apply lead-free flux prior to soldering in accordance with applicable plumbing codes such as the IPC. Allow the joint to cool fully before restoring system pressure.
