Hayward Drain Cap, Gasket & Screen for ProSeries Sand Filters | SX180LA

The Hayward Drain Cap, Gasket & Screen (SX180LA) is the OEM replacement drain assembly for Hayward ProSeries sand filters, restoring a watertight seal at the tank drain port and keeping debris out of the drain passage.

This three-piece assembly — drain cap, sealing gasket, and screen — works together to seal the lower drain port on the filter tank. The screen prevents sand and debris from entering the drain passage, while the gasket ensures a leak-free closure when the cap is tightened. Replace this assembly when the drain cap shows cracking, when the gasket no longer seals, or when the screen is clogged or damaged.

Compatibility is based on Hayward parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Poolaroo Pro Tip

When servicing the drain port, inspect the gasket for compression set or cracking before reinstalling — a gasket that looks intact may no longer seal under pressure. Replace the full assembly (cap, gasket, and screen together) rather than individual pieces to ensure a consistent, leak-free fit. Hand-tighten the cap firmly; over-tightening can crack the cap or distort the gasket seat.
