About This Item

The Hayward Clamp System (DEX2421JKIT) is the OEM replacement clamp assembly — including clamp, seal, hardware, and labels — for Hayward SwimClear Multi-Element Cartridge Filters and ProGrid DE Filters. This complete kit supplies every component needed to restore the tank clamp band assembly to factory specification in a single order.

The clamp system secures the filter tank halves together and maintains a pressure-tight seal during operation. Replacing a worn or damaged clamp assembly restores the structural integrity of the filter housing and prevents pressurised water loss at the tank joint.

Poolaroo Pro Tip

When replacing the clamp assembly, inspect the filter tank rim and mating groove for debris or scale buildup before seating the new seal. Even minor contamination at the joint can prevent the clamp from achieving a full pressure seal. Torque all hardware fasteners evenly in an alternating pattern to distribute clamping force uniformly around the tank circumference.
