KleenWater brand water filter housing replacement o-ring for 3M Purification Aqua-Pure AP801 / AP802. We recommend consumers keep a spare o ring on hand to avoid urgent situations. This o ring will accommodate filter housings which require large diameter cartridges. These cartridges have an approximate diameter of 4.5 inches. The o-ring itself actually measures approximately 5 5/8 inch (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.
