Hayward O-Ring Kit (Set of 2) for SwimClear Cartridge Filters and ProGrid DE Filters | DEX2420Z8A

Description

The Hayward O-Ring Kit (DEX2420Z8A) is the OEM replacement two-piece O-ring set for Hayward SwimClear Multi-Element Cartridge Filters and ProGrid DE Filters. This kit supplies both O-rings required to restore a proper pressure seal at the filter tank.

IMPORTANT: LUBRICATION REQUIRED — SOLD SEPARATELY
Always lubricate these O-rings with a silicone-based lubricant before installation. Browse our Pool Plumbing Lubricants for a compatible silicone lubricant.

This two-piece kit provides the sealing O-rings that maintain a watertight closure on the filter tank assembly. Replacing worn, cracked, or distorted O-rings eliminates leaks at the filter head and restores operating pressure integrity.

Fits Into

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

Before seating these O-rings, clean the groove channels of any debris, dried lubricant, or old rubber residue. Apply a thin, even coat of silicone-based lubricant — never petroleum-based grease, which degrades rubber — to the O-rings prior to installation. Find a compatible lubricant in our Pool Plumbing Lubricants collection. Inspect and replace these O-rings at each seasonal opening as a low-cost step that prevents leaks and pressure loss throughout the swim season.
