Replacement lid designed for Waterway pressurized filter canisters featuring a top-load configuration. This 6 1/4" filter cap measures across the lip and is engineered to fit Waterway pressurized filter housings.

The lid design incorporates a channel for a thick o-ring that creates a seal against the interior lip of the filter canister. A bleeder thumb screw port with o-ring is integrated into the cap, allowing you to release trapped air from the filter housing following cartridge replacement or when refilling your spa with fresh water.

Important Purchase Information: This replacement lid is sold as the cap component only. The large sealing o-ring and bleeder thumb screw with o-ring are not included with this item and must be purchased separately if needed.

Common Wear Pattern: These lids are prone to developing cracks in the center section beneath the handle, which can result in water leakage. If you notice dripping from this area, replacement is recommended.
