RO6G DEX2422Z2 Replacement Filter Seal Gasket for Hayward Pro Grid & SwimClear — Black O-ring with Lubricant

RO6G DEX2422Z2 is a direct-fit replacement O-ring gasket engineered to restore a leak-free seal for compatible Hayward Pro Grid and SwimClear pool filters.

When your Hayward filter shows signs of leaking, poor suction, or frequent pressure fluctuations, the culprit is often a worn or damaged seal. The RO6G DEX2422Z2 filter seal gasket is made to match Hayward's specified dimensions for many Pro Grid vertical DE and SwimClear cartridge models, providing a reliable, flexible seal that resists abrasion and tearing. Each package includes one DEX2422Z2 gasket and a tube of lubricant to make installation smoother and reduce the risk of pinch or twist during fitting.

How does the RO6G DEX2422Z2 stop leaks in my Hayward filter?

The gasket creates a continuous, compression-fit barrier between the filter housing and the lid or cartridge assembly, preventing water from bypassing the filtration elements. Proper sealing restores rated pump pressure and reduces water loss from the system.

• Precision molded to Hayward DEX2422Z2 specifications for an accurate fit.
• Flexible compound conforms to housing irregularities for a consistent seal.
• Included lubricant ensures correct seating without twisting or pinching.

Which Hayward models are compatible with this replacement seal?

This RO6G seal fits a range of later-model Hayward Pro Grid vertical DE filters and SwimClear cartridge filters. It is designed for units manufactured after 2009, so double-check your filter model and production year before ordering.

• Compatible Pro Grid models: DE2420, DE3620, DE4820, DE6020, DE7220.
• Compatible SwimClear cartridge models: C2020, C3020, C4020, C5020.
• Not compatible with Pro-Grid DE or SwimClear models made before 2009.

What materials and durability can I expect from this gasket?

The RO6G DEX2422Z2 gasket is manufactured from a heavy-duty elastomer that balances flexibility with abrasion and tear resistance. That composition helps maintain a dependable seal through repeated pressure cycles and routine pool chemistry exposure when maintained correctly.

• High-flex compound resists permanent deformation during installation.
• Abrasion- and tear-resistant formulation extends replacement intervals.
• Supplied lubricant reduces installation wear and helps preserve the seal.

How simple is installation and what tools or steps are needed?

Installing the RO6G DEX2422Z2 is straightforward for most DIY users familiar with pool equipment. Always power down pumps and lock out equipment before servicing; the included lubricant and clear seating fitment minimize installation errors.

• Turn off and lock out all pool pump power before beginning work.
• Wear gloves, remove the old gasket, apply supplied lubricant, and fit the new seal into the housing groove.
• Reassemble the filter, pressurize slowly, and inspect for leaks before resuming normal operation.

Who is this for: The RO6G DEX2422Z2 filter seal gasket is aimed at pool owners and service technicians who need a dependable, OEM-spec replacement for mid-2009-and-later Hayward Pro Grid and SwimClear filters. If you value a precision fit, durable elastomeric material, and a bundle that includes installation lubricant, this gasket provides a cost-effective way to restore filter performance and stop leaks without replacing the entire filter assembly.
