1" PVC Schedule 40 Coupling – Solvent Weld Socket for Non-Pressurized DWV Applications

The 1" Schedule 40 PVC coupling is a straight socket-style fitting used to join two sections of 1" nominal PVC pipe. Manufactured in accordance with ASTM standards, this fitting is suitable for non-pressurized drain, waste, and vent (DWV) applications. It is commonly solvent-welded into place using PVC primer and cement to form a permanent, watertight joint.

Its internal dimensions are machined to accommodate standard Schedule 40 pipe, providing a reliable connection point for both new installations and system modifications where pipe extension or repair is required.

Product Specifications

• Material: PVC Type I (Cell Classification 12454 per ASTM D1784)
• Nominal Size: 1 inch
• Connection Type: Slip x Slip (Socket x Socket)
• Wall Type: Schedule 40
• Temperature Rating: 140°F (maximum continuous service temperature)
• Applicable Standards: ASTM D2466, NSF/ANSI 14 (DWV use)

Typical Use Cases

• Non-pressurized drain and vent systems
• Sanitary waste piping (aboveground)
• Condensate drain line connections
• Repair sleeves and section replacements

Installation Guidelines

Installation requires the use of PVC primer and solvent cement, applied per manufacturer and local code guidelines. Ensure both pipe ends are cut square, deburred, and dry-fit prior to bonding. Full insertion depth should be marked on pipe to verify joint integrity during assembly.

Code and Environmental Considerations

This fitting is intended for aboveground, non-pressurized systems only. It should not be used for potable water distribution or for underground burial without additional support or approval. Always verify compliance with local plumbing codes and approved materials lists before use.

Performance Summary

The 1" PVC Schedule 40 coupling provides a cost-effective and code-compliant method for joining lengths of PVC piping in DWV systems. Its solvent weld design delivers long-term joint integrity, supporting reliable system operation in a variety of residential and light commercial applications.
