Hayward Drain Cap Gasket Kit for VariFlo Valves and ProSeries Sand Filters | SX200Z9

The Hayward Drain Cap Gasket (SX200Z9) is the OEM replacement gasket kit for VariFlo multiport valve assemblies and ProSeries sand filters, restoring a watertight seal at the drain cap port. IMPORTANT: KIT CONTENTS This listing is sold as a kit. Confirm what is included in the kit against your equipment's exploded diagram or parts manual before ordering to ensure you receive the correct components for your service need. The drain cap gasket creates a compression seal between the drain cap and the valve or filter body, preventing water and air leakage at the drain port. Replacing a worn, cracked, or deformed gasket eliminates drips at the drain cap and restores proper system pressure.

Poolaroo Pro Tip Before installing the new gasket, clean the drain cap seat and mating surface on the valve or filter body to remove any residue or old gasket material. A clean, flat seating surface is essential for achieving a leak-free seal. Inspect the drain cap itself for cracks or deformation — a damaged cap will continue to leak regardless of gasket condition.
