Hayward SX200Z9 Drain Cap Gasket

What This Part Is Used For
The Hayward SX200Z9 is a drain cap gasket used on compatible Hayward sand filters. It seals the drain cap so the filter can hold water and pressure without leaking from the drain port. This gasket sits at the drain assembly near the base of the filter tank.

Why This Part Matters
A worn drain gasket can cause steady dripping at the bottom of the filter, especially after winterizing and reopening. Even a small leak at the drain adds up and can damage pads and surrounding equipment. Replacing the gasket restores a reliable seal without over-tightening the cap. It also keeps draining and refilling clean and controlled during service.
