The Oil Seal 17x25x6 NBR TC (17x25x6 mm) renews the sealing on a 17 mm shaft where grease or oil must stay in and grit must stay out — a typical fitment in compact motors, power tools, small pumps and precision gear units.

About the TC profile
TC seals work with a triple defence — a rubber-coated case seating tightly in the bore, a main lip held against the shaft by a garter spring, and an outer dust lip that keeps abrasive particles away.
About the NBR nitrile compound
The compound is NBR nitrile, selected for oil-and-grease compatibility across motors, reducers and pumps. Note the limits: brake fluid degrades nitrile, and sunlight ages stored rubber — so store spares dark and dry.
Should the shaft read slightly below the listed size — typically a few tenths of a millimetre — no concern: the lip’s interference fit accounts for it.
