Hayward SwimClear Clamp Bolt & Nut

Genuine Hayward replacement clamp bolt and nut for compatible SwimClear filter systems upgraded to the DEX2421JKIT clamp assembly.

Warranty Information

6-Month Manufacturer Warranty

Ultimate Pools is your first point of contact for compatibility verification, installation guidance, and warranty support.

The Hayward SwimClear Clamp Bolt and Nut (DEX2421J2) is a genuine Hayward replacement fastener assembly used with compatible filter clamp systems. It is designed specifically for filters equipped with the DEX2421JKIT clamp system.

The original clamp bolt, nut and spring assembly has been discontinued. The DEX2421J2 is not compatible with the original clamp band system, making clamp-system verification especially important on older SwimClear models before ordering.

Frequently Asked Questions

Will the DEX2421J2 fit every SwimClear filter listed?

Will this work with the original SwimClear clamp band?
No. The DEX2421J2 is not compatible with the original clamp band system.
Why do older SwimClear filters require extra verification?
Models such as C2020, C2025, C3020, C3025, C4020, C4025, C5020, C5025 and C7000 may still have the original clamp band installed rather than the newer DEX2421JKIT system.
What happened to the original bolt, nut and spring assembly?
The original clamp bolt and nut with spring assembly has been discontinued. This replacement is intended for the newer DEX2421JKIT clamp system.
Is the DEX2421J2 final sale?
Yes. This replacement clamp hardware is final sale, so verify both your filter model and installed clamp system before ordering.
