OmniFilter OK7 O-Ring

The Omni Filter OK7 O-Ring set fits the OmniFilter BF7 heavy duty whole house water filter system.

The OK7 contains 2 O-rings

• O-ring 1 is 5-5/8" (inside diameter) X 5-7/8" (outside diameter)
• O-ring 2 is 5-3/4" (inside diameter) X 6-1/8" (outside diameter)

Time and exposure to water, air, etc. can slowly deteriorate the O-ring material, causing it to become hard & brittle, allowing tiny cracks to form. These cracks eventually grow, the O-ring fails, and you end up with a leak.

We recommend replacing your O-rings with every 3rd filter change - especially if your filter system is installed in a place where leaks could cause water damage.

In-between O-ring changes, you can extend the life of your O-rings with our Food-Grade Silicone O-ring Grease. The grease is non-toxic, safe, and designed specifically to improve sealing & increase the life of O-rings used in water filter systems.
