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.
Material: NBR – Nitrile
This is an NBR-nitrile seal — the everyday elastomer for oil-lubricated equipment, compatible with mineral oils, greases and hydraulic media. For longest life, avoid brake fluid contact and store spares away from direct sunlight.
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.
