Seal and O-ring care for ULTRAWF
Keep seals clean and avoid unapproved lubricants or tools. The published Frigidaire record identifies this cartridge as PureSource Ultra Water Filter.
Start with fit verification
Match the complete refrigerator model and the code printed on the existing cartridge. Genuine Frigidaire PureSource Ultra filter. Match the filter code and refrigerator model before ordering. Do not infer compatibility from color, overall shape or brand alone.
Service baseline
The available record uses 6 months or 200 gallons, subject to the manufacturer’s whichever-comes-first instructions. Water quality, usage and long periods of inactivity may justify earlier service.
Safe action
Slide the new filter into the housing and push until it locks into place; consult the Use & Care Guide. If the cartridge does not seat normally, water does not return after flushing, or the housing leaks, stop and use the refrigerator’s model-specific manual.
Evidence
Open the linked source before purchase. FilterRef separates published compatibility from general troubleshooting guidance and does not treat an aftermarket cross-reference as automatically equivalent.
