Water Filter Replacement O Rings For PWFHT2520BT.

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. We recommend consumers keep a spare O Ring on hand to avoid urgent situations.
