Mueller Streamline W-1727 Copper Flush Bushing

Product Description

The MUELLER STREAMLINE W-1727 is a flush-pattern copper bushing used to reduce pipe connections in sweat-soldered copper systems. It features a 7/8-inch male sweat (fitting) end and a 1/2-inch female sweat end, allowing a technician to step down tubing size within a fitting assembly without adding length to the joint. This type of fitting-to-fitting (FTG) bushing seats flush inside a standard copper fitting socket, making it a compact solution for tight spaces. Licensed plumbers and HVAC technicians install this part in residential and light commercial piping systems where copper sweat connections are specified.

This bushing is suited for use in potable water supply lines, hydronic heating systems, refrigerant piping, and general copper tubing assemblies. The flush design integrates directly into a standard cup-end fitting, eliminating the need for a separate adapter piece. It is sold individually and is appropriate wherever a 7/8-inch to 1/2-inch sweat reduction is required in a copper piping run.

Key Features

• Flush bushing profile seats inside a standard copper fitting socket for a compact, low-profile reduction
• 7/8-inch male sweat (FTG) by 1/2-inch female sweat (FS) end configuration
• Copper construction for compatibility with sweat-solder joining methods
• Sold individually (each) for precise quantity purchasing
• Suitable for potable water, hydronic, and HVAC refrigerant piping applications

Compatibility

Designed as an OEM-style copper sweat fitting for use in standard copper tubing systems requiring a 7/8-inch to 1/2-inch flush bushing reduction.

Installation Notes

Installation is performed by a licensed plumber or qualified HVAC technician following applicable local plumbing codes and ASTM standards for copper sweat fittings. Shut off and drain the water or fluid supply before beginning work, and allow all piping to reach ambient temperature before handling. Clean and flux both the male and female mating surfaces before applying solder to ensure a leak-free joint. Do not overheat the fitting during soldering, as excessive heat can damage the copper material and compromise joint integrity.
