The Replacement OmniFilter OK7 O-Ring Kit The Replacement OmniFilter OK7 O-Ring Kit (also called OK7-DC6-S06, OK7-R-01, OK7-R-02, OK7-S6-05, OK7-DC6-S18) contains 2 different o-ring sizes to fix your leaking water system. This convenient 2-set package contains 2 of each size, for a total of 4 o-ring gasket seals.

Compatibility and Important Information The OK7 o-rings are compatible with the following OmniFilter water filter housings: BF6, BF7, BF7a (BF7 Series A), BF35, BF36, BF36C, BF55, BF56, PB35, and PB55.

It's important to note that some filter models on the compatibility list may use the smaller o-ring, while others use the larger o-ring. Some revisions of the same filter model may also use different o-ring sizes. Please make sure to try both o-ring sizes in the kit to confirm the correct fit for your housing.

FAQ: Water Filter O-Ring Replacement and Maintenance How often should I change the o-ring in my filter housing? Captain O-Ring's high-quality replacement o-rings are designed for reliable extended use. It is typically recommended to replace the o-ring on every third filter change to ensure it remains in top shape and prevents leaks.

Can I use grease or lubricant on these o-rings? Since Captain O-Ring supplies high-quality o-rings without surface imperfections or a tacky/sticky texture, lubrication is typically not needed if the filter housing sealing surfaces are clean and free of debris. You can simply wet the o-rings with water before installing. However, if lubrication is preferred, these Buna Nitrile rubber o-rings are compatible with silicone-based, petroleum-based, and natural lubricants like vegetable oil.

What if I don't know the o-ring part number for my filter housing? Use our handy printable water filter housing o-ring size chart to determine the correct size. You can find the size chart listed as "User Guide [PDF]" under the "Product guides and documents" section or the "downloads" section on this page.
