4 inch ABS DWV Coupling Plastic x Plastic

4 inch ABS DWV Coupling – Engineered for Secure Drainage System Integration

The 4 inch ABS DWV Coupling is a solvent weld fitting designed to connect two sections of 4-inch ABS pipe in drainage, waste, and vent (DWV) systems. Manufactured in compliance with ASTM D2661, this fitting is suitable for gravity-fed sanitary systems and is intended for non-pressurized applications.

Its one-piece, molded construction ensures dimensional consistency and structural integrity under standard plumbing system loads. ABS material provides high impact resistance and stable performance over a wide range of operating temperatures, making it well-suited for above-ground and in-wall installations.

Product Advantages

• ✅ Code-Conforming Design Complies with model plumbing codes and ASTM standards for DWV applications.
• ✅ Solvent Weld Connections Compatible with standard ABS solvent cement for chemically bonded joints.
• ✅ Durability Resistant to corrosion, scaling, and deformation under thermal cycling.
• ✅ Lightweight Profile Facilitates handling and alignment in confined spaces or multi-branch assemblies.
• ✅ Inert Composition Non-reactive with standard DWV effluent and compatible with other ABS fittings and pipe.

Technical Specifications

• Material: Acrylonitrile Butadiene Styrene (ABS)
• Nominal Size: 4 inches
• End Connections: Hub x Hub (slip fit for solvent weld)
• Applicable Standards: ASTM D2661, CSA B181.1
• Application: Non-pressure DWV piping systems

Installation Notes

For proper installation, ensure that both pipe ends are chamfered and cleaned prior to applying solvent cement. Use a compatible ABS cement per ASTM D2235 for a full-depth insertion bond. Allow appropriate cure time based on ambient temperature and pipe diameter before testing the system.

Typical Use Cases

This coupling is utilized in residential, commercial, and institutional drainage systems for horizontal or vertical pipe connections. It is frequently employed in branch drain assemblies, fixture tie-ins, and system modifications requiring alignment or extension of existing 4-inch ABS lines.

Material Insight

ABS is commonly used in DWV systems for its strength-to-weight ratio, ease of installation, and resistance to biological and chemical agents commonly found in waste lines. Unlike PVC, ABS does not require a primer for solvent welding.

The 4 inch ABS DWV Coupling is a standard component in code-approved DWV system installations. It delivers consistent joint integrity and performance reliability under typical system conditions.
