1-1/2 inch x 1-1/4 inch Copper Flush Bushing – Reducing Fitting for Sweat Applications

The 1-1/2 inch x 1-1/4 inch Copper Flush Bushing is a precision-formed fitting used to reduce pipe size in soldered copper systems. Designed for use in drainage, waste, vent (DWV), and potable water distribution, this fitting allows for efficient transitions between different pipe diameters while maintaining system continuity and compliance with dimensional tolerances.

Constructed from wrought copper, the flush bushing provides a low-profile reduction ideal for applications with limited clearance. The cup (female) and spigot (male) ends are engineered to match standard copper tube sizing for seamless integration into sweat-joined systems.

Fitting Characteristics

• ✅ Material: Wrought copper, typically C12200 (deoxidized, high-phosphorus copper).
• ✅ End Connections: 1-1/2 inch female sweat x 1-1/4 inch male sweat.
• ✅ Design Profile: Flush bushing allows for space-saving reduction within fittings or valves.
• ✅ Corrosion Resistance: Suitable for potable water and DWV applications.
• ✅ Lead-Free Compliance: Conforms to NSF/ANSI 61 and 372 for use in potable systems where required.

Applicable Standards

• ASTM B75/B88/B306: For copper tube materials and specifications
• ASME B16.22: Standard for wrought copper and copper alloy solder-joint pressure fittings
• NSF/ANSI 61 & 372: Certification for lead-free plumbing system components

Installation Guidance

This flush bushing is intended for sweat (soldered) connection. Ensure surfaces are cleaned and properly fluxed before applying heat. Avoid overheating to prevent distortion. For water distribution systems, pressure testing should be conducted in accordance with applicable plumbing code prior to final wall closure or backfill. Do not use in pressurized gas systems unless explicitly rated for such applications.

Typical Applications

This reducing bushing is commonly used in residential and commercial construction to transition between copper tubing sizes in branch lines, valve assemblies, or fixture risers. It is especially useful in retrofits where original piping must be adapted to modern fixture or equipment inlets with smaller diameters.

Regulatory Note

Copper fittings used in potable systems must meet lead-free requirements in accordance with the U.S. Safe Drinking Water Act. This product satisfies such regulations when installed per code.

The 1-1/2 inch x 1-1/4 inch Copper Flush Bushing provides a reliable, code-compliant solution for reducing copper pipe size in soldered plumbing systems. With its compact form factor and standardized fitment, it is ideal for professional applications where dimensional accuracy and long-term performance are required.
