Culligan HD-950 Compatible Water Filter Housing Replacement Oring

The KleenWater brand KW101 oring will accomodate filter housings which require large diameter cartridges. These cartridges have an approximate diameter of 4.5 inches. The oring itself actually measures approximately 5.465 inch (inside diameter). We recommend consumers keep a spare o ring on hand to avoid urgent situations.

An oring 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.
