A neoprene sealing O-ring designed for plunger-style twist waste assemblies in commercial faucet and sink systems, providing a tight seal at the internal plunger section to control water flow during drain operation. The ring features a 1-7/8\" inner diameter and 2-1/4\" outer diameter, allowing it to fit within compatible twist waste mechanisms where controlled sealing is required for proper operation. This sealing component is commonly used in commercial sinks and plumbing fixtures found in foodservice kitchens, prep stations, and utility wash areas. When the O-ring becomes worn, flattened, or cracked, it may lead to leakage or improper drain sealing. Replacing the component may restore proper sealing at the plunger assembly and support normal water control during sink operation in busy kitchen environments.

\n\n

Equipment Compatibility:
Primary applications for this T&S Brass plunger O-ring include commercial sink drain systems, twist waste assemblies, and plumbing fixtures used in foodservice operations. This Plunger O-Ring 010389-45 is compatible with commercial equipment from leading brands such as T&S Brass, and more, where internal plunger sealing is required for normal operation.

\n\n

Brand Compatibility:
Replaces multiple part numbers used across commercial plumbing and sink systems from T&S Brass. Complete cross-reference details are provided separately in the “Replaces Parts” section.

\n The T&S Brass 010389-45 O-Ring Waste Drain Plunger is a replacement sealing component designed for commercial sink waste drain valve assemblies. Featuring a 1-7/8\" inside diameter and 2-1/4\" outside diameter, this O-ring fits within compatible drain plungers to help create a sealed connection during operation. Installed in the plunger groove, it compresses between connected parts to assist with water containment and drain control in rotary waste drain systems. Commonly used in commercial kitchen sinks and plumbing fixtures, this component supports maintenance and repair applications for select waste drain valve models.\n
