About This Item

The Hayward Tank Bolt Set (ECX1642A) is the OEM replacement hardware set for securing the filter tank on Perflex Extended-Cycle DE Filters and the ProSeries 23" Sand Filter.

This bolt set provides the clamping hardware that draws the filter tank halves or lid together, maintaining a pressure-tight seal during operation. Replacing worn, corroded, or stripped tank bolts restores proper tank closure and prevents leaks at the tank seam.

Compatibility is based on Hayward parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Poolaroo Pro Tip

When replacing tank bolts, inspect the tank O-ring or gasket at the same time. A new bolt set won't cure a leak caused by a deteriorated seam seal — address both together to avoid a second disassembly.
