1-1/2 inch PVC DWV Coupling Plastic x Plastic

1-1/2” PVC DWV Coupling – Schedule 40, Solvent Weld Socket x Socket

The 1-1/2” PVC DWV Coupling is a solvent-weld fitting designed to join two sections of Schedule 40 PVC pipe in drain, waste, and vent (DWV) systems. Manufactured to ASTM D2665 standards, this coupling provides a smooth, consistent interior surface that reduces flow restrictions and helps maintain system velocity in horizontal and vertical piping runs.

Constructed from rigid Type I Grade I PVC, this coupling is designed for gravity-flow DWV applications and is intended for non-pressurized systems in both residential and commercial installations. Its socket ends are engineered for solvent cement connections using ASTM D2564-compliant cement and primer systems.

Technical Specifications

• Nominal Size: 1-1/2 inches
• Material: PVC (Cell Class 12454 per ASTM D1784)
• Fitting Type: Straight Coupling
• Connection Type: Slip Socket x Slip Socket (Solvent Weld)
• Applicable Standards: ASTM D2665, NSF 14 certified, CSA B181.2 compliant
• Temperature Rating: Up to 140°F (60°C) in non-pressurized systems

Installation Guidelines

Ensure pipe ends are clean, square-cut, and free of burrs. Apply primer and solvent cement per ASTM D2855, insert pipe to full socket depth, and hold briefly to allow initial bond formation. Avoid pressurizing or testing the system until full cure time has elapsed. Follow all local code requirements and manufacturer's instructions for solvent-weld joint assembly.

Typical Applications

This coupling is used in horizontal or vertical DWV systems for fixture branches, mainline extensions, and cleanout assemblies. Suitable for installations in walls, ceilings, floor assemblies, and slab-on-grade layouts. Often specified for residential drainage retrofits and code-compliant new construction builds.

Code and Material Notes

PVC DWV fittings offer excellent corrosion resistance, dimensional stability, and resistance to chemical degradation in waste systems. The smooth bore and solvent-weld connection minimize the risk of blockages and ensure long-term system performance in accordance with national and local plumbing codes.

Code-Compliant Coupling for Schedule 40 PVC DWV Systems

The 1-1/2” PVC DWV Coupling delivers a reliable solution for joining PVC pipe segments in non-pressurized waste and vent systems. Its standard dimensions and solvent-weld design offer fast, consistent installations that meet the performance and inspection standards required on modern plumbing jobsites.
