This TC oil seal measures 38x70x10 mm and is machined for a 38 mm shaft rotating inside a 70 mm housing — a dimension you will meet in electric motors, gearboxes, pumps and agricultural machinery.

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
Material-wise this is NBR nitrile: a balanced compound for mineral oil, diesel-range fuels and greases at moderate temperatures — ideal for rotating equipment. Two cautions: no exposure to glycol-based brake fluid, and keep stock seals out of 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.
