This o-ring will accommodate the filter housings referenced above which require large diameter cartridges which have an approximate diameter of 4.5 inches. The o-ring itself actually measures approximately 5 3/4" (inside diameter). An o-ring facilitates a water tight seal between the water filter sump and the water filter head. The most common o-rings used in water filtration are made from Buna N material. Buna N is also commonly referred to as nitrile. This is the ideal choice for cold water filtration because they are inexpensive and have superior performance characteristics.
