The 20x35x5 mm Oil Seal 20x35x5 NBR TC keeps lubricant circulating where it belongs — inside the housing — on the 20 mm shafts and 35 mm bores typical of light-duty motors, drills, mini pumps and small gearbox assemblies.

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.
Material: NBR – Nitrile
The seal lip is moulded from NBR, a nitrile rubber prized for resistance to mineral oil, grease and hydraulic fluids — the default elastomer for general machinery. It should not meet brake fluid, and stored spares fare best away from UV light.
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.
