Oil Seal, 1.750X3.000X0.313

TCM Oil Seal, 1.750 X 3.000 X 0.313

The 17303TB-H TCM Oil Seal is a dual-lip radial shaft seal with a garter spring designed to keep oil and grease where it belongs while helping block out dust and grime. With a nitrile (NBR) lip and an outer metal case, it’s a dependable choice for rotating shafts in gearboxes, pumps, and driveline equipment—because “self-lubricating shop floor” is not a feature.
