O-Ring for OmniFilter U25 Whole House Filter

The Omnifilter OK25 O-ring is the replacement o-ring for the Omnifilter U25 Series A, B, C & D. This o-ring is also used in the Omnifilter U27 Whole House Water Filter System. The OK25 creates a tighter seal, which reduces the chance of leakage that may cause water damage. To ensure the best performance, replace these o-rings after every third water filter change.
