Product details

The Hayward DEX2422Z2 is the tank seal that sits between the two halves of a Pro-Grid DE or SwimClear cartridge filter. Unlike a plain o-ring, it has a metal ring molded inside, which keeps the gasket seated in its groove while the clamp is drawn down and stops it from stretching or rolling out under pressure.

Fitment

It fits Pro-Grid DE2420, DE3620, DE4820, DE6020 and DE7220 DE filters and SwimClear C2020, C3020, C4020 and C5020 cartridge filters. It applies only to tanks built after March 2009 that use the DEX2421JKIT aluminum clamp. Earlier tanks take a different seal, so check the build date on the tank label before ordering.

Dimensions

Outside diameter is 20-5/8 in. and inside diameter is 19-7/8 in.

Installation

Clean both tank flanges, seat the seal in the groove without lubricant that could let it slip, then fit and tighten the clamp evenly. If the tank has been weeping at the belt line after a clean and reassemble, a tired seal is the usual cause.

Questions and answers

What people ask about this product, answered by our pool techs.

How do I know if my filter takes this seal?
It is for Pro-Grid and SwimClear tanks built after March 2009 that close with the DEX2421JKIT aluminum clamp. Older tanks, and tanks with a different clamp, use a different seal.
Why is the seal metal reinforced?
The steel ring inside the gasket holds its shape. A plain rubber o-ring of this size can stretch, twist or squeeze out of the groove as the clamp is tightened.
Which filter models does it fit?
Pro-Grid DE2420, DE3620, DE4820, DE6020 and DE7220, and SwimClear C2020, C3020, C4020 and C5020.
What are the dimensions?
20-5/8 in. outside diameter and 19-7/8 in. inside diameter.
