Technical Specifications

Part Number: SX200G
Function: Manual air relief vent cap for sand filter tanks.
Application: In-ground sand filters in pool equipment systems.

Installation & Compatibility Notes

To install, shut off the filter pump and relieve system pressure. Unscrew the old air-relief cap from the filter tank lid, clean the seal surface, and install the new SX200G cap, ensuring it seats correctly. After installation, restore circulation and verify that the filter pressure returns to normal and that no air pockets remain.

Maintenance Tips

Inspect the cap periodically for cracks, worn threads or ineffective sealing — replace if any issue is found.
If the filter pressure climbs unusually or airflow seems reduced, use the cap to vent air and evaluate whether the filter media or laterals may also be at fault.
Keep the part in your standard service parts inventory — it’s a common replacement on filter maintenance visits.

Why Choose This Cap?

For pool service professionals and homeowners alike, the Hayward SX200G offers a cost-effective, OEM-matched solution to maintain safe and efficient filter operation. Proper air relief helps prevent premature media wear, improves circulation, and supports long-term filter performance.
