The Hobart 00-067500-00072 Dishwasher O-Ring is a circular sealing component used in selected commercial dishwashing equipment. It sits between connected parts to form a seal and limit leakage around the fitting or assembly. The O-ring measures approximately 13/16 inch in inside diameter and 1/8 inch in width. It may be considered when an existing dishwasher seal becomes cracked, flattened, stretched, or unsuitable for continued service.
