Watts WOR-FF O-Ring for Full Flow Housings

The Watts WOR-FF o-ring is a rubber gasket for Watts Full Flow whole house housings. The WOR-FF can be used on all Watts clear or opaque full flow water filter housings. This o-ring is a tubular o-ring rather than a flat o-ring. Approximately 6-inch in width. The Watts WOR-FF o-ring also fits the PurePro WF-10 and the PurePro WF-20 water filter housings. The WOR-FF o-ring should be replaced approximately every two filter changes or if there is damage to the WOR-FF oring.
