Mueller Industries 15698 Copper Flush Bushing 3/4x3/8 Ftg X C

Product Description

The MUELLER INDUSTRIES 15698 is a wrot copper flush bushing used to reduce pipe or fitting connections from a 3/4 inch to a 3/8 inch diameter within a copper piping system. The end connection is FTG x C, meaning the male end slips into a fitting socket while the female end accepts a standard copper tube. With an outside diameter of 7/8 inch on the larger end and 1/2 inch on the smaller end, this bushing allows for compact, in-line reductions without adding significant length to the assembly. Plumbers and HVAC technicians install this fitting in potable water, hydronic heating, refrigeration, and general copper piping applications where a concentric reduction is required.

This flush bushing suits residential and light commercial copper piping installations where a smooth, low-profile transition between pipe sizes is needed. The FTG x C configuration makes it compatible with standard sweat-solder assembly methods. Typical applications include branch line reductions, equipment connections, and fixture supply lines. The wrot copper construction meets the demands of both pressure and temperature conditions common in plumbing and HVAC systems. Sold in a package quantity of 5 per unit.

Key Features

• Wrot copper construction for reliable sweat-solder joints in pressure piping systems
• 3/4 inch x 3/8 inch reducing configuration for concentric in-line transitions
• FTG x C end connection integrates directly into standard copper fitting assemblies
• Outside diameter of 7/8 inch x 1/2 inch for accurate socket fit verification
• Flush bushing profile minimizes added length in tight spaces
• Sold in a package of 5 fittings per order unit

Compatibility

Designed as an OEM-style replacement and standard-use fitting for copper piping systems using 3/4 inch x 3/8 inch sweat-solder connections with FTG x C end configurations.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician using standard sweat-soldering tools including a torch, flux, and lead-free solder compliant with applicable plumbing codes. Shut off the water supply and depressurize the line before cutting or fitting. Ensure all mating surfaces are clean, deburred, and properly fluxed before applying heat. Follow local plumbing codes, including IPC requirements, for approved solder alloys in potable water applications.
