6 inch PVC DWV Coupling – For Gravity-Flow Drain, Waste, and Vent Piping

The 6 inch PVC DWV Coupling is a non-pressure fitting designed to connect two sections of 6-inch DWV pipe in horizontal or vertical configurations. Manufactured from rigid polyvinyl chloride, it provides a solvent-welded connection suitable for gravity-driven wastewater and venting systems in both residential and commercial applications.

Engineered to meet ASTM performance standards, this coupling ensures dimensional consistency, chemical resistance, and long-term reliability in sanitary drainage systems. Its socket ends allow for secure solvent welding using approved primers and cements, forming a permanent bond that resists leaks under standard DWV conditions.

Performance Features

• ✅ Rigid PVC Material – Designed for corrosion resistance and dimensional stability in non-pressurized waste systems.
• ✅ Socket End Connections – Accommodates standard 6 inch DWV piping with solvent weld compatibility.
• ✅ Code-Compliant Geometry – Manufactured to ASTM D2665 and D3311 specifications for PVC DWV fittings.
• ✅ Non-Metallic Construction – Eliminates risk of galvanic corrosion when integrated with other plastic piping components.
• ✅ Low-Maintenance Design – Suitable for concealed installations in wall cavities, crawlspaces, and slab systems.

Technical Specifications

• Material: Polyvinyl Chloride (PVC)
• Size: 6-inch nominal pipe size
• Connection Type: Slip/socket (solvent weld)
• Applicable Standards: ASTM D2665, D3311, and UPC/IPC plumbing code compliance

Typical Applications

This DWV coupling is used in sanitary drainage and vent piping systems for residential, commercial, and institutional projects. It connects straight pipe runs or repairs cut sections within gravity-flow systems handling gray water, black water, or air venting.

Installation Consideration

All joining surfaces should be properly cleaned and prepared using PVC primer before solvent cement application. Allow adequate cure time as specified by the cement manufacturer before system testing.
