COMPATIBILITY & APPLICATIONS
Compatible Filter Housings
This gasket is specifically engineered for use with 3M Aqua-Pure AP801 and AP802 whole-house water filter housings manufactured by Pentair. The AS568-357 O-ring dimensions ensure a precise fit within the housing sump, creating a watertight seal that prevents bypass and maintains system pressure. This replacement gasket is essential for routine maintenance during filter cartridge changes, typically recommended every 6-12 months depending on water quality and household usage. Regular gasket inspection and replacement prevents slow leaks that can lead to water damage and ensures your filtration system operates at peak efficiency.
💧 Apply a thin layer of food-grade silicone lubricant to the gasket before installation to ensure proper seating, extend O-ring life, and make future housing removal easier during filter changes.
