3 inch ABS DWV Coupling – Reliable Performance for Drainage Systems

The 3 inch ABS DWV Coupling is designed for secure, solvent-welded connections in non-pressurized drain, waste, and vent systems. Manufactured from high-impact ABS (Acrylonitrile Butadiene Styrene), this fitting provides a strong, consistent joint between 3 inch DWV pipe sections and is suitable for residential and commercial plumbing installations.

Product Features

• Material: Injection-molded ABS for dimensional accuracy and durability
• Connection Type: Hub x Hub – designed for solvent cement joining
• Application: DWV (Drain, Waste, Vent) systems only – not for pressurized water or gas
• Temperature Rating: Suitable for continuous service up to 140°F (60°C)
• Corrosion Resistance: Will not rust or degrade when exposed to wastewater and sewer gases

Standards and Compliance

• Manufactured to ASTM D2661 (ABS DWV fittings)
• Listed to NSF Standard 14 for DWV applications
• UPC (Uniform Plumbing Code) certified for code compliance

Installation Guidance

The coupling is solvent-welded using ABS cement, which chemically bonds the pipe and fitting to form a permanent, pressure-tight seal. Ensure that all joining surfaces are clean and dry before applying cement. Use appropriate solvent cement that meets ASTM D2235 requirements for ABS materials.

This fitting is intended for use in gravity drainage systems only and should not be subjected to pressure applications. It is commonly used in horizontal and vertical DWV lines to extend or repair existing pipe runs.

Common Use Cases

The 3 inch ABS coupling is typically installed in sanitary waste lines under floors, behind walls, or within vent stacks. Its compact, uniform structure makes it a practical solution for retrofits, new builds, or code-compliant repairs where 3 inch ABS DWV pipe transitions are required.

Technical Tip

Unlike PVC, ABS does not require a primer prior to solvent welding. However, adequate drying time after assembly is crucial before water testing or backfilling. Follow manufacturer cure time guidelines based on ambient temperature and humidity.

Built to meet the demands of modern DWV systems, the 3 inch ABS Coupling offers reliability, code compliance, and ease of installation in a wide range of drainage applications.
