1-1/2 inch PVC Schedule 40 Coupling Plastic x Plastic

1-1/2 inch PVC Schedule 40 Coupling – Solvent Weld Connector for Non-Pressure DWV Systems

The 1-1/2 inch PVC Schedule 40 coupling is a straight, slip-style fitting designed for solvent-welded joints in drain, waste, and vent (DWV) systems. Manufactured from rigid polyvinyl chloride (PVC), this coupling is intended for use in gravity-flow, non-pressure applications where dimensional consistency and code compliance are required.

Both ends are socket-style for insertion of 1-1/2 inch nominal Schedule 40 PVC pipe, allowing for secure bonding with primer and solvent cement. The fitting conforms to recognized standards for thermoplastic DWV piping systems used in residential, commercial, and institutional construction.

Specifications

• Material: PVC Type I (Cell Classification 12454 per ASTM D1784)
• Nominal Size: 1-1/2 inch
• Connection Type: Slip x Slip (Socket)
• Wall Rating: Schedule 40
• Standards Compliance: ASTM D2466, NSF-listed for DWV applications

Application Scope

• Non-pressurized sanitary waste lines
• Vent piping in residential and light commercial buildings
• Condensate drainage systems
• Retrofitting and repair of gravity DWV installations

Installation Notes

This coupling must be joined using approved PVC primer and solvent cement per local plumbing code requirements. Pipe ends should be clean, square-cut, and deburred before insertion into the fitting socket. Once assembled, allow adequate cure time before system testing or backfilling. Do not use for pressurized potable water or gas systems.

Product Performance

Schedule 40 PVC is chemically resistant, non-conductive, and immune to electrolytic corrosion. Its light weight and workability contribute to faster installation in both new construction and renovation environments.

Summary

The 1-1/2 inch PVC Schedule 40 coupling is a standard component in solvent-weld DWV assemblies. Designed for dimensional accuracy and durability, it supports efficient installation and code-compliant performance in gravity-based drainage and venting applications.
