Hayward Replacement Filter Seal DEX2422Z2 — Metal‑Reinforced Cartridge & D.E. Gasket, Restores Tight Leak-Free Seal

The Hayward DEX2422Z2 is a metal-reinforced replacement filter seal engineered to restore a tight, durable seal in select Hayward ProGrid and SwimClear cartridge filters.

When a worn or damaged filter seal lets bypass or causes leaks, the entire cartridge filtration system becomes less efficient. This Hayward DEX2422Z2 seal is designed as a direct-fit replacement for several popular Hayward vertical D.E. and cartridge filter models, bringing back proper sealing, improved water flow control, and extended filter life without replacing the entire housing.

Which filter models does this replacement seal fit?

The DEX2422Z2 is compatible with multiple Hayward ProGrid vertical D.E. filter models and older SwimClear cartridge filters. It’s intended to match factory dimensions for a secure fit and correct sealing action.

• ProGrid vertical D.E. models: DE2420, DE3620, DE4820, DE6020, DE7220
• SwimClear cartridge models: C2020, C3020, C4020, C5020
• Metal-reinforced design for dimensional stability under pressure

How does the metal reinforcement improve performance?

The metal reinforcement prevents the seal from deforming under system pressure and heat, keeping the gasket profile consistent and reducing the chance of leaks or bypass around the cartridge head. This yields steadier filtration performance and fewer service interruptions.

• Resists compression set and swelling compared with plain rubber seals
• Maintains correct sealing pressure at high flow rates
• Improves longevity of the gasket under repeated service cycles

What should I expect when installing this replacement seal?

Installation is straightforward for anyone familiar with cartridge or vertical D.E. filter maintenance. The replacement seal installs in the filter head or canister groove where the original gasket sat and creates a uniform seal when the lid or head is reassembled.

• Remove old gasket, clean sealing surfaces, and inspect for damage
• Seat the new DEX2422Z2 metal-reinforced seal into the groove evenly
• Reassemble per filter manual and check for leaks under pressure

Will this part affect flow rate or filtration quality?

When installed correctly, the DEX2422Z2 restores the intended sealing capability of the filter system; it does not change the cartridge media or filter rating and therefore won’t alter the designed flow rate or filtration efficiency. Its role is to prevent leaks and bypass so the filter can operate as originally engineered.

• Restores designed water path through cartridges or D.E. grids
• Prevents unfiltered water from bypassing cartridges or grids
• Supports consistent system pressure and predictable run-times

Who is this for: Pool owners and service technicians who use Hayward ProGrid vertical D.E. or SwimClear cartridge filters and need a reliable, OEM-compatible gasket to stop leaks and maintain proper filtration. It’s a cost-effective part for routine maintenance and for replacing seals that have aged, cracked, or compressed.
