Mueller Industries W 01712 Copper Flush Bushing 3/8x1/4

Product Description

The MUELLER INDUSTRIES W 01712 is a wrot copper flush bushing designed to reduce a 3/8-inch fitting-end connection down to a 1/4-inch cup-end connection using a solder joint. This fitting is used in copper piping systems where a smooth, flush reduction is required without adding significant length to the assembly. Wrot copper construction provides consistent wall thickness and excellent solderability. The FTG x C end configuration means the male fitting end inserts directly into a standard cup-end fitting or valve, making it a common choice for tight-space reductions in refrigeration, plumbing, and HVAC piping work. Outside diameter measures 1/2 x 3/8 inches.

This flush bushing is suited for residential and light commercial applications where copper piping systems require an in-line size reduction. Typical installations include domestic water lines, HVAC refrigerant-adjacent copper assemblies, and hydronic piping. Plumbers and HVAC technicians install this fitting wherever a compact, low-profile bushing is preferable to a standard reducing coupling. The solder joint connection method requires proper flux application and a torch-applied sweat solder process in accordance with applicable codes.

Key Features

• Wrot copper construction for consistent wall thickness and reliable solder joints
• Flush bushing profile minimizes added length in tight installations
• FTG x C end connection inserts directly into a standard cup-end fitting
• Meets ASME B16.22 and ASME B16.18 standards for wrought copper and cast copper alloy fittings
• Also conforms to ASME B16.15, ASME B16.24, ASME B16.50, and ASME B1.20.1
• Lightweight at 0.0111 pounds per unit

Compatibility

Designed as an OEM-style replacement or new-installation fitting for standard copper solder-joint piping systems using 3/8-inch to 1/4-inch reductions.

Installation Notes

Installation is performed by licensed plumbers or HVAC technicians familiar with torch-soldering copper fittings. Shut off and depressurize the water or fluid system and allow all components to cool before working on the line. Clean all mating surfaces with emery cloth and apply an approved flux before soldering per ASME and applicable local plumbing codes. Do not overheat the fitting, as excessive heat can damage the copper or wick solder past the joint.
