Hayward Clamp Ring Kit, New Style Pro-Grid DE / Swim-Clear, DEX2421JKIT

The Hayward DEX2421JKIT is the genuine clamp ring kit for new style Pro-Grid DE filters and Swim-Clear cartridge filters. It is supplied as the complete clamp system.

New style only

This is the part to get wrong if you order in a hurry. The kit fits the new style clamp only, and an older filter with the earlier clamp arrangement takes different hardware. Compare the clamp on your tank against the one pictured before ordering, and if there is any doubt, check the model and the build of the filter first.

Why it matters

The clamp ring is what holds the two halves of the filter body together against system pressure. It is not a part to improvise around or to reassemble with a piece missing, and a corroded or damaged clamp is replaced rather than patched. Ordering the kit gets the clamp system as Hayward supplies it.
