COMPATIBILITY & APPLICATIONS
Fits Frigidaire Inline Filter Systems
This rear o-ring is designed as a direct replacement seal for Frigidaire 154246901 and 154247001 filter housings commonly found in refrigerator water filtration systems and under-sink inline filter assemblies. The AS568-231 standard sizing ensures proper compression and sealing against housing walls to prevent bypass or leakage at the rear cap. Compatible with Pentair and Frigidaire branded inline filter housings that specify these OEM part numbers. Inspect o-ring groove for debris or damage before installing new seal to ensure optimal contact surface.
💧 Replace the rear o-ring any time you service the filter housing or notice moisture around the cap threads — a fresh seal costs less than water damage and ensures full system pressure integrity.
