Hayward SX180LA Drain Cap, Gasket and Screen - For S180T

What This Part Is Used For
The Hayward SX180LA is a drain cap, gasket, and screen set specified for the Hayward S180T sand filter. It seals the drain port during operation and provides screening support at the drain opening during service. This assembly installs at the base of the filter tank.

Why This Part Matters
A worn drain cap seal is a common cause of steady dripping from the bottom of the filter, especially after winterizing and reopenings. If the cap or gasket will not seal, the filter can leak continuously while running. Replacing the complete set restores proper sealing and makes draining the filter cleaner during service. It also helps prevent overtightening that can strip drain threads.
