Water Filter Housing Replacement O Ring For 4 1/2 Inch Housings. We recommend consumers keep a spare o ring on hand to avoid urgent situations. This o ring will accomodate 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 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 (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.
