2 inch ABS DWV Coupling – Solvent Weld Fitting for Non-Pressurized Drainage Systems

The 2 inch ABS DWV Coupling is a straight-line solvent weld fitting used for joining two 2 inch nominal ABS pipes in non-pressurized drainage, waste, and vent (DWV) systems. Designed for above-ground installations, this coupling provides a secure, rigid connection that maintains system integrity across horizontal or vertical piping layouts.

Technical Specifications

• Material: ABS (Acrylonitrile Butadiene Styrene), Cell Classification 22222 per ASTM D3965
• Nominal Size: 2 inches
• Connection Type: Hub x Hub (female solvent weld sockets)
• Applicable Standards: Conforms to ASTM D2665 (DWV fittings), NSF-certified for DWV system use
• Operating Temperature: Up to 140°F in non-pressurized service

Performance Characteristics

• ✅ Non-Corrosive – Resistant to most household and commercial waste stream chemicals
• ✅ Rigid Structure – Maintains alignment under thermal expansion and mechanical stress
• ✅ Solvent Weld Bonding – Ensures a permanent, watertight seal when installed per ASTM D2855 guidelines
• ✅ Lightweight Handling – Allows for ease of transport, cutting, and installation without specialized tools

Installation Guidance

Intended for use in gravity flow DWV systems. Pipe ends must be clean, square-cut, and dry-fit before solvent cement application. Use only approved ABS solvent cement (primer not required for ABS). Observe proper joint cure times before testing or placing into service. Not for use in pressurized or hot water systems.

Common Use Cases

This fitting is typically used to join sections of 2 inch ABS pipe in sanitary drainage systems, including fixture branches, vent offsets, and long horizontal runs. Suitable for residential, multi-family, and light commercial installations where rigid, leak-resistant connections are required.

Material Note

ABS is a non-metallic thermoplastic with high impact strength and thermal stability, making it ideal for DWV systems installed in wall cavities, soffits, or basements. It is not UV-resistant and should be protected from direct sunlight when used outdoors or in exposed settings.

The 2 inch ABS DWV Coupling is a code-compliant, solvent-weld fitting engineered for fast, reliable pipe connections in drain and vent piping assemblies. Manufactured to industry standards, it offers a long-lasting solution for joining ABS pipe in new construction or retrofit DWV applications.
