One 15x25x7 mm part does the sealing: the Oil Seal 15x25x7 NBR TC wraps a 15 mm shaft in its spring-loaded lip and presses firmly into a 25 mm bore — the kind of fit seen across light-duty motors, drills, mini pumps and small gearbox assemblies.

How the TC design works
The TC arrangement — rubber-covered case, garter-spring main lip, external dust lip — is the industry’s go-to solution wherever a shaft spins in an oil-filled housing.
Why NBR for this seal
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.
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.
