TonGass Replacement Kit for Hayward SP1023

Upgrade your above-ground pool with the TonGass 2-pack inlet return fitting set. This kit is designed as an exact-feel replacement for the Hayward SP1023 and includes four components: a flanged lock nut, two distinct gaskets, a fiber washer, and the inlet fitting body. Produced by TonGass as an aftermarket solution with OEM-quality testing, this set is not officially affiliated with Hayward, but aims to deliver reliable, ready-to-install performance for compatible systems.

What makes this kit useful

• Inlet versatility: The assembly provides both 1.5" external threads and internal threads for hose fittings, supporting threaded-to-clamp adapters or slip x MPT connections for flexible plumbing.
• Outlet compatibility: The 1.5" internal threads on the FIP inlet open up options for plugs, outlet covers, directional fittings, jetnozzles, and other aftermarket components.
• Leak-resistance design: The combination of the lock nut and gasket is crafted to help secure the fitting through fiberglass pools or vinyl liners, reducing the chance of leaks at the connection.
• Simple installation: Replacing the old inlet is designed to be straightforward—remove the old part, slide in the FIP inlet, add the gasket, and tighten with the lock nut for a quick setup.
