The Oil Seal 15x32x8 NBR TC is a TC rotary shaft seal sized 15x32x8 mm (ID × OD × width). It keeps oil inside and dirt outside on a 15 mm shaft seated in a 32 mm bore — a size common in micro motors, angle grinders, cooling pumps and compact gear reducers.

Inside the TC double-lip design
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.
Why NBR for this seal
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.
It is normal for a shaft to measure a few tenths of a millimetre smaller than nominal; the sealing lip is engineered to take up that difference.
