2 inch x 1 inch Copper Reducing Coupling – Precision Fit for Copper DWV Systems

The 2 inch x 1 inch copper reducing coupling is designed to transition between different nominal copper tube sizes in drain, waste, and vent (DWV) systems. Manufactured to strict tolerances, this coupling provides a smooth, secure connection that supports efficient system flow and long-term durability.

Product Benefits

• Lead-Free Copper Construction: Fabricated from high-purity, lead-free copper alloy, this fitting complies with federal and state requirements for potable water systems.
• Sweat (Cup x Cup) Ends: Designed to be soldered, offering a permanent, tamper-resistant joint ideal for non-pressurized DWV systems.
• Optimized for DWV Applications: Specifically engineered for use in copper DWV installations where consistent fit and corrosion resistance are priorities.
• Corrosion Resistance: Copper's natural resistance to scaling and microbial growth makes it a preferred material for sanitary waste systems.

Technical Specifications

• Material: Copper (Lead-Free)
• Size: 2 inch x 1 inch nominal tube size
• Connection Type: Sweat (Cup) x Sweat (Cup)
• Compliance: ASME B16.29 and NSF/ANSI standards
• Application: Copper DWV systems

Installation Notes

Installation requires standard soldering techniques using flux and lead-free solder. Pipes should be properly deburred and cleaned prior to assembly. For vertical and horizontal DWV runs, ensure joints are aligned with directional flow to prevent turbulence or pooling.

Common Applications

This reducing coupling is typically installed in residential and commercial DWV systems to accommodate transitions in pipe size—such as connecting fixture branches or modifying stack diameters. It is suitable for use behind walls, under floors, or in accessible mechanical rooms.

Code Considerations

This product meets national and local plumbing code requirements for DWV use. Its lead-free designation also supports compliance with Safe Drinking Water Act amendments for potable applications, if required.

When pipe sizing transitions are required in a copper DWV system, the 2 inch x 1 inch reducing coupling provides a precise, code-compliant solution that professionals can rely on for long-term service and performance.
