An authentic OEM sourced replacement part that is specially designed for use with Karcher pressure washers. This is the special o-ring which helps to ensure the proper air-tight seal between the pressure hose and the pistol adapter.

Over time o-rings tend to deteriorate and may crack eventually requiring replacement to maintain the proper seal.
