Replace the worn seal on a 42 mm shaft with the Oil Seal 42x80x12 NBR TC — 42x80x12 mm, TC profile, NBR compound — it drops into a 80 mm bore and stops the leak. Popular in AC motors, worm gearboxes, gear pumps and harvest machinery.

How the TC design works
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.
NBR nitrile rubber at a glance
Made of NBR (acrylonitrile-butadiene rubber), the seal tolerates the mineral oils and lithium greases that lubricate most machinery. Standard practice: keep NBR away from brake fluid, and store unused seals in their bag, out of sunlight.
Don’t worry if your micrometer shows the shaft a few tenths under size — the garter-sprung lip is designed to seal against exactly that condition.
