American Granby SCH 40 PVC Slip Cap ¾"

Capping off unused plumbing lines cleanly and permanently is a common requirement in pool and spa systems, especially during repairs, remodels, or equipment changes. The American Granby Schedule 40 3/4” PVC Cap (Slip) is a professional-grade fitting designed to seal the end of a 3/4” Schedule 40 PVC pipe with a strong, pressure-rated solvent-weld connection.

This cap is manufactured specifically for pool and spa plumbing environments, where chemical exposure, constant water pressure, and outdoor conditions demand reliable materials and precise fit. It is not a temporary plug—it is intended for permanent installations where a line must be safely closed.

Why PVC Caps Are Used in Pool Plumbing

Pool systems often require unused or abandoned lines to be sealed to prevent leaks, pressure loss, or debris intrusion. Using an incorrect cap or makeshift solution can result in future failures.

The American Granby 3/4” PVC slip cap is used to:

• Permanently cap unused plumbing lines

• Close off abandoned chemical or auxiliary lines

• Seal plumbing during system reconfiguration

• Terminate test lines or future expansion points

A properly installed slip cap ensures a clean, durable seal that won’t 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 3/4” Schedule 40 PVC pipe.

Once glued, the cap becomes a permanent part of the plumbing system, providing:

• A smooth internal seal

• Full pressure-rated performance

• Long-term leak resistance

Slip caps are preferred in pool plumbing because they eliminate threaded leak points.
