AppliaFit Dome Lid Replacement for Hayward S200 S240 Filters — SX200K Compatible, Heavy-Duty UV-Stable Cap

AppliaFit Dome Lid Replacement is a heavy-duty replacement cap designed to restore proper sealing and protect the internals of Hayward S200 and S240 series sand filters (compatible with Hayward part SX200K).

If your pool filter lid is cracked, warped, or no longer sealing reliably, replacing it with a durable aftermarket dome lid can stop leaks and keep the sand filter operating efficiently. This AppliaFit lid is engineered to fit Hayward S200 and S240 series assemblies and matches the SX200K compatibility spec so you can replace a worn cap without changing your existing filter plumbing or hardware.

Will this lid fit my Hayward sand filter model?

Yes — this dome lid is sized and shaped to be compatible with Hayward part number SX200K and with the S200 and S240 series sand filters. It was made to align with the same bolt pattern and sealing area used on those models, so installation is straightforward when the original lid dimensions are intact.

• Compatible models: Hayward S200 and S240 series
• Direct replacement for Hayward part SX200K
• Designed to match original bolt pattern and sealing surface
• Works with existing clamps and hardware when undamaged

How durable is the AppliaFit dome lid and what materials are used?

The lid is made from heavy-duty molded material chosen for impact resistance and long-term performance in outdoor pool environments. It resists UV exposure and regular pool chemicals better than thin, brittle caps, helping you avoid frequent replacements.

• Robust molded construction for resistance to cracking
• UV-stable formulation to reduce sun degradation
• Designed to withstand typical pool chemical exposure
• Manufactured to meet practical lifespan expectations for pool equipment

How easy is installation and what tools do I need?

Installation is a simple swap: remove the old lid, clear the sealing surface, set the AppliaFit dome in place, and secure using your filter's original clamp and bolts. No special tools are required beyond common hand tools, and most users can complete the change in under an hour.

• Remove original lid and inspect the gasket area
• Clean sealing surface before installing the new lid
• Use existing clamp/bolts; typical tools: screwdriver or wrench
• Check for proper clamp tension and test for leaks after installation

What should I know about compatibility and branding?

This AppliaFit replacement is an aftermarket part made to be compatible with Hayward models for convenience and cost-efficiency. Brand names and logos are the property of their respective owners; AppliaFit uses these model references solely to indicate fit and interchangeability.

• Aftermarket part engineered for compatibility, not an original Hayward-manufactured component
• Model references used only to identify correct fit (SX200K, S200, S240)
• Packaging may differ from OEM packaging
• Inspect your existing hardware to confirm no additional parts are needed
