American Granby SCH 40 PVC Slip Cap 1"
When a pool plumbing line needs to be permanently sealed, the cap must be pressure-rated, chemically resistant, and sized correctly to avoid future leaks. The American Granby Schedule 40 1” PVC Cap (Slip) is a professional-grade fitting designed to securely cap the end of a 1” 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 are exposed to constant pressure, chlorinated water, and outdoor conditions. It is commonly used during repairs, system reconfigurations, and new construction when a line must be closed cleanly and permanently.
This is not a temporary plug or test cap—it is a true Schedule 40 pool-grade PVC cap.
Why PVC Caps Are Used in Pool Plumbing
Pool systems often include auxiliary lines, abandoned runs, or future expansion points that must be safely sealed. Improper capping methods can lead to leaks, pressure loss, or hidden failures underground.
The American Granby 1” PVC slip cap is used to:
-
Permanently cap unused or abandoned plumbing lines
-
Seal auxiliary or chemical feeder lines
-
Close off plumbing during equipment upgrades
-
Terminate lines during remodels or reroutes
-
Prepare systems for pressure testing
A properly solvent-welded cap provides a clean, long-lasting seal.
Slip Cap Design Explained
This fitting features a Slip (socket) connection, which solvent-welds directly over the outside of a 1” Schedule 40 PVC pipe.
Once installed with primer and cement, the cap becomes a permanent part of the plumbing system and provides:
-
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 failure or loosening over time.
Schedule 40 PVC Built for Pool & Spa Systems
Manufactured from rigid Schedule 40 PVC, this cap is pressure-rated for residential and light commercial pool systems. It is fully compatible with standard 1” Schedule 40 PVC pipe used throughout pool plumbing.
The material resists:
-
Chlorinated and chemically treated water
-
UV exposure and temperature fluctuations
-
Cracking and deformation under pressure
-
Long-term outdoor and underground conditions
This ensures dependable performance anywhere a line is capped.
