Engineered as a direct replacement, the Oil Seal 25x32x7 NBR TC (25x32x7 mm) seals 25 mm shafts against dust and moisture from the moment it seats in the 32 mm bore — common in workshop motors, helical gearboxes, vane pumps and tractor attachments.

About the TC profile
Every TC seal combines three elements: a rubber-covered case that grips the bore, a spring-loaded sealing lip that follows shaft runout, and a dust lip that shields the main lip from contamination.
Material: NBR – Nitrile
NBR (Nitrile) is the standard compound for general industrial sealing. It handles mineral oils, greases and hydraulic fluids, which is why it is the default choice in gearboxes, electric motors and pumps. Keep it away from brake fluid, and store spare seals out of direct sunlight.
If your shaft measures a few tenths of a millimetre under the nominal size, that is normal — the sealing lip is designed with interference for exactly that.
