Hobart 00-067500-00120 Dishwasher O-Ring Overflow Tube

Secured to commercial dishwasher drain and overflow tube assemblies, this O-ring serves as a sealing component that maintains a tight interface between the overflow tube and adjoining housing, preventing water leakage during wash and drain cycles. It functions by compressing around the connection point to form a reliable watertight seal, helping regulate proper water retention and drainage balance within the system. Placed inside Hobart commercial dishwashing units, it features a 1-3/4 inch outer diameter designed for accurate fitment in compatible overflow tube assemblies and ensures consistent sealing performance under repeated thermal and water pressure cycles. Commonly used in commercial warewashing equipment in restaurants, cafeterias, and institutional kitchens, it plays an important role in maintaining controlled water levels and preventing internal leaks. When an aged or damaged O-ring loses elasticity, it may lead to dripping or improper drainage; replacing it restores proper sealing, stable water control, and efficient dishwasher operation.
