The Oil Seal 22x42x7 NBR TC (22x42x7 mm) renews the sealing on a 22 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
The TC layout brings three protections together: a rubber outer surface that grips the housing bore, a garter-spring lip that tracks slight shaft movement, and a secondary dust lip that blocks grit before it reaches the sealing edge.
About the NBR nitrile compound
Nitrile rubber (NBR) is the workhorse of oil sealing: fully compatible with mineral oils, lubricating greases and common hydraulic fluids — the media found in most gearboxes and motors. Avoid contact with brake fluid, and keep spares shaded from sunlight.
Don’t worry if your micrometer shows the shaft a few tenths under size — the garter-sprung lip is designed to seal against exactly that condition.
