Hayward SX180HG Drain Cap and Gasket - For S180T

What This Part Is Used For
The Hayward SX180HG is a drain cap and gasket set specified for the Hayward S180T sand filter. It seals the drain port at the base of the filter so the tank holds water and pressure during normal operation. This assembly is located at the bottom drain area on the equipment pad.

Why This Part Matters
A worn gasket or damaged drain cap is one of the most common causes of steady dripping from the bottom of a sand filter. After winterizing or draining for service, the old seal often will not reseat and the leak returns as soon as the pump runs. Replacing the cap and gasket restores a dependable seal without overtightening and stripping threads. It also makes future drain downs cleaner and more controlled.
