Product details

The Hayward DEX2420F is the bulkhead fitting used on the Pro-Grid DE filters and the SwimClear cartridge filters. The nut portion of the part carries a DE2420F stamp, which is why owners often find it listed under that second number.

What a bulkhead fitting does

Anywhere a pipe passes through the wall of a filter tank, something has to carry it and seal it. That is the bulkhead. It is not a glamorous part, but the whole tank depends on it holding, and when it fails the symptom is distinctive: water weeping around the port rather than running out of the plumbing itself.

Check your model

This fitting is listed across two filter families. On the cartridge side that is SwimClear C2020/C2025, C3020/C3025, C4020/C4025, C5020/C5025 and C5520. On the DE side it is the Pro-Grid range, and the two sources do not agree exactly: one lists DE2420, DE3620, DE4820 and DE7220, the other adds DE6020. We have carried both lists here rather than choosing one.

One more thing to confirm

The source describes this item both as a bulkhead fitting and, in one place, as a bulkhead diffuser o-ring. If you are ordering to fix a specific leak, tell us what you are looking at and we will confirm the right piece.

Questions and answers

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

Why does the part show two numbers?
The manufacturer part number is DEX2420F, and DE2420F is stamped into the nut portion of the part. Both refer to the same fitting.
Which filters does it fit?
Hayward SwimClear cartridge filters in the C2020/C2025, C3020/C3025, C4020/C4025, C5020/C5025 and C5520 sizes, and the Pro-Grid DE filters. The Pro-Grid list differs slightly between sources: one covers DE2420, DE3620, DE4820 and DE7220, the other adds DE6020. Check your model against both before ordering.
Is this the fitting or an o-ring?
The source is not consistent. The product is titled as a bulkhead fitting and one description calls it a bulkhead diffuser o-ring. Confirm with us which piece you need before ordering.
What does a bulkhead fitting do?
It carries a port through the wall of the filter tank and seals against the shell. When it fails, water weeps around the port instead of running through the plumbing.
