Only need one of the two sizes in the Omnifilter OK7 kit?

Since Omnifilter has multiple revisions/submodels within each of the compatible models for the OK7 o-ring kit, your exact filter may need either the larger or smaller o-ring inside.  We always recommend purchasing the whole OK7 kit the first time you need to replace o-rings for these filter models, but once you know which of the two o-ring sizes your exact housing needs, you can purchase that size individually:
  • The smaller/thinner o-ring in the OK7 kit is the Pentek Pentair 151122 o-ring.
  • ​The larger/thicker o-ring in the OK7 kit is the 3M 68898-32 o-ring.
