Why the TC profile is so widely used
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.
NBR nitrile rubber at a glance
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.
