Fits Watts Full Flow Housings
This WOR-FF o-ring is designed exclusively for Watts Full Flow (B-B) style big blue filter housings in both 10-inch and 20-inch configurations. The Full Flow design features a threaded cap where the filter cartridge screws directly into the housing head, requiring this specific AS568-337 dimension o-ring to seal properly. Not compatible with standard sump-style housings that use different o-ring sizes. Inspect o-rings during every filter change and replace if compression set, cracking, or hardening is visible.
