2 inch Copper DWV Coupling less Stop Copper x Copper

2 inch Copper DWV Coupling – Designed for Secure Drainage System Transitions

The 2 inch Copper DWV Coupling is a seamless connector for joining two lengths of copper drainage, waste, and vent piping. Manufactured to meet industry-standard tolerances, this fitting ensures a smooth internal flow path and reliable soldered joints in low-pressure DWV systems.

Produced from lead-free copper alloys, this coupling provides long-term corrosion resistance and structural stability in residential, commercial, and institutional drainage applications. Its consistent dimensional profile supports clean installation and alignment within vertical and horizontal runs.

Professional-Grade Features

• ✅ Lead-Free Copper Alloy: Compliant with health and safety codes for non-pressurized DWV systems.
• ✅ Socket x Socket Design: Straight-through configuration enables consistent joint preparation and soldering.
• ✅ Uniform Wall Thickness: Supports proper heat transfer during soldering for permanent joint integrity.
• ✅ Corrosion Resistance: Withstands common wastewater conditions without compromising mechanical performance.
• ✅ Code-Compliant Fabrication: Manufactured to ASTM B306 and ASME B16.29 standards for copper DWV fittings.

Technical Specifications

• Nominal Size: 2 inch
• Material: Lead-free copper (typically C12200)
• Connection Type: Female sweat (cup) x Female sweat (cup)
• Application: Drainage, waste, and vent piping (non-pressurized systems only)
• Compliance: ASTM B306, ASME B16.29, NSF/ANSI 61 where applicable

Use Case Summary

This coupling is intended for use in copper DWV systems requiring alignment and permanent connection between straight pipe sections. It is commonly installed behind walls, in crawl spaces, and in basement drainage layouts where soldered copper piping is specified by design or code.

Industry Note

All copper fittings used in plumbing systems intended for human contact or drainage must be lead-free under federal legislation (Reduction of Lead in Drinking Water Act). This coupling meets those criteria and is acceptable for both new construction and remodel applications.

The 2 inch Copper DWV Coupling offers reliable fit, long-term corrosion protection, and system compliance—making it a practical and professional choice for drainage piping assemblies requiring sweat connections in copper infrastructure.
