American Granby SCH 40 PVC Slip Cap 1½"

When a pool plumbing line needs to be permanently sealed, the cap must be properly sized, pressure-rated, and chemically resistant to ensure long-term reliability. The American Granby Schedule 40 1 1/2” PVC Cap (Slip) is a professional-grade fitting designed to securely cap the end of a 1 1/2” Schedule 40 PVC pipe using a solvent-weld connection intended for permanent pool and spa installations.

This cap is manufactured specifically for pool and spa plumbing systems, where capped lines may remain pressurized, buried, or exposed to chlorinated water and outdoor conditions. It is commonly used during repairs, system reconfigurations, and new construction when a plumbing line must be closed cleanly and permanently.

Why PVC Caps Are Used in Pool Plumbing

Pool systems frequently include unused, abandoned, or future-use lines that must be safely sealed to prevent leaks and pressure loss. Improper capping can lead to hidden failures that are difficult and costly to repair.

The American Granby 1 1/2” PVC slip cap is used to:

• Permanently cap unused plumbing lines

• Seal abandoned suction or return runs

• Close off lines during equipment upgrades

• Terminate plumbing during remodels or reroutes

• Prepare systems for pressure testing

A properly solvent-welded cap provides a clean, durable seal that will not loosen over time.

Slip Cap Design Explained

This fitting features a Slip (socket) connection, allowing it to solvent-weld directly over the outside of a 1 1/2” Schedule 40 PVC pipe.

Once installed with primer and cement, the cap becomes a permanent part of the plumbing system and delivers:

• Full pressure-rated performance

• No threaded leak points

• Long-term durability in pool environments

Slip caps are preferred in pool plumbing because they eliminate the risk of thread damage or loosening.
