Mueller Industries 15681 Copper Flush Bushing 3/4x1/2 Ftg X C

Product Description

The MUELLER INDUSTRIES 15681 is a wrot copper flush bushing designed to reduce a 3/4 inch fitting connection down to a 1/2 inch copper tube connection within a single compact fitting. The FTG x C end configuration — fitting end by copper tube end — allows the bushing to seat inside a standard socket fitting, keeping the assembly tight and low-profile. Wrot copper construction ensures high ductility and reliable soldered joints in both potable water and mechanical piping systems. This bushing is installed by licensed plumbers during new construction, remodel, or repair work where pipe size transitions are required without adding extra couplings or fittings.

This flush bushing is suited for residential and light commercial plumbing systems where a 3/4 inch branch or main line must transition to a 1/2 inch branch line. The FTG x C connection style is a standard configuration used throughout copper piping systems and is compatible with conventional sweat soldering methods. It is commonly found in domestic water supply systems, HVAC hydronic piping, and refrigeration copper line applications requiring a clean, in-line size reduction.

Key Features

• Wrot copper construction provides superior strength and leak-resistant soldered joints compared to cast fittings
• FTG x C end connection allows the bushing to insert directly into a standard 3/4 inch socket fitting
• Flush bushing profile keeps the size transition compact and in-line without added fitting bulk
• 3/4 inch x 1/2 inch reduction size handles one of the most common branch transitions in residential plumbing
• UNSPSC Code 40175305 for streamlined procurement and materials tracking

Compatibility

Designed as an OEM-style replacement or new-installation component for standard wrot copper sweat fitting assemblies in 3/4 inch to 1/2 inch size-reduction applications.

Installation Notes

Installation should be performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and fully drain the affected line before cutting or fitting work begins. Clean and flux all mating surfaces thoroughly before soldering to ensure a sound, leak-free joint. Do not use open-flame torches near combustible materials without proper heat shielding in place.
