This replacement 151122 (also called OR-100) O-ring is used to seal Big Blue water filter housings from Pentek as well as a number of other brands. It has an inside diameter of 5-1/2" and outside diameter of just over 5-3/4 inches and is made of nitrile butadiene rubber (Buna-N) for flexibility and resistance to abrasion and tearing. The o-ring fits many Pentek Big Blue filter housings (as well as dozens of similar housings from other brands), which are used in various applications, such as drinking water purification, swimming pools, industrial processes, and more.

Captain O-Ring's OEM size o-ring fits perfectly into the groove of Big Blue Filters.  No need to stretch or squeeze o-rings with two sets of hands like off-sized aftermarket o-rings.  Our o-rings are packaged flat, and not curled into undersized bags, so the o-ring lays flat in your filter housing instead of being twisted.  Changing your o-ring with a Captain O-Ring OEM size replacement takes only 4-5 seconds once the housing is removed from the filter head.
