1-1/2 inch PVC Schedule 40 Cap

Schedule 40 PVC Cap – Designed for Secure Pipe Termination

The Schedule 40 PVC Cap is engineered for closing off the end of a pressure or drainage line in both residential and commercial plumbing systems. Fabricated from rigid polyvinyl chloride (PVC), this cap provides a solvent-weld connection that ensures a permanent, watertight seal under a variety of operating conditions.

Its heavy-duty Schedule 40 wall thickness meets ASTM D2466 specifications, making it suitable for use in cold water pressure systems, irrigation setups, and DWV (drain-waste-vent) piping where permanent closure is required. The smooth interior minimizes flow restriction when used in capped test lines or cleanouts prior to permanent system pressurization.

Key Product Features

• Material: High-impact Schedule 40 PVC
• Connection Type: Socket (Slip) end for solvent welding to male pipe
• Temperature Rating: Up to 140°F for non-pressurized systems
• Applications: Cold water lines, irrigation systems, DWV terminations, system pressure testing
• Standards: Meets or exceeds ASTM D2466 and NSF 14/61 for potable water applications

Installation Guidelines

Ensure all pipe ends are properly deburred and clean before solvent welding. Use primer and PVC solvent cement that meet ASTM F656 and F493 standards, respectively. Allow sufficient cure time per ambient temperature and pressure before system pressurization. For test assemblies, this cap can be temporarily installed and later removed using a suitable fitting extractor if needed.

Common Use Cases

• Permanent closure of dead-end pipe runs
• Test capping prior to system inspection
• Sealing branch lines in non-pressurized drainage systems

Did You Know?

Schedule 40 PVC fittings like this cap are preferred in many code-compliant installations due to their corrosion resistance, ease of assembly, and long service life in non-metallic systems.

For professional-grade sealing of open PVC pipe ends, the Schedule 40 PVC Cap delivers the durability and reliability required by contractors working to meet code and performance expectations.
