Conforming this part will replace the top body of a Hayward Cartridge 425 circa 2008-10 where the inside diameter is approximately 19 inches and the outside (where the gasket seat is) is approximately 21.25 inches. The height of the old body is approximately 16 inches tall (this does not include height of the pressure relief valve).
Hi, Mike. Yes, this Filter Head w/ Clamp Assembly - DEX4820BTC will fit your model Hayward Filter. The Manual Air Relief Assembly - DEX2420MAR2 is NOT included.

Very much appreciate the quick reply..another question... If the outside diameter of my top is 21.25 inches how is it possible for the 22.5" diameter top to fit on the existing body. This part has a diameter that is 1.25" greater than the existing Unit And the clamp will not work. Appreciate the clarification.
