The Oil Seal 12x22x5 NBR TC (12x22x5 mm) renews the sealing on a 12 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.

Inside the TC double-lip design
The TC arrangement — rubber-covered case, garter-spring main lip, external dust lip — is the industry’s go-to solution wherever a shaft spins in an oil-filled housing.
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.
It is normal for a shaft to measure a few tenths of a millimetre smaller than nominal; the sealing lip is engineered to take up that difference.
