Product overview
The Filter Clamp and Seal Kit with Manual Air Relief Assembly is an aftermarket seal built to replace the original component in Hayward filtration systems. In service it keeps water out of the motor side of the pump while allowing the shaft to rotate. It is a wear item: the sealing faces score and leak, which lets water reach the motor bearings — a failure that destroys the motor if left unattended. This part is cross-referenced to 2 Hayward OEM numbers — DEX2421JKIT, DEX2420MAR2 — so buyers working from a number stamped on a failed component can confirm the match before ordering.
