- An oil seal, also known as a lip seal, is a mechanical device designed to prevent the passage of oil or other fluids while allowing the rotation or linear movement of shafts and axles. The Oil Seal 20 34 7, with its specific dimensions of 20mm inner diameter, 34mm outer diameter, and a 7mm width, is tailored to fit various applications where precise sealing is required.

Chemical resistant
Low coefficient of friction poor elastic properties not wear resistant if used by dynamic applications
As an example, this oil seal has a part number that corresponds to a Shaft Size of 3”, a Bore Size of 4”, a Width Size of 0.625”, a Style of TB2, and is made of Viton material. Conversely, the same size oil seal in Metric has a Shaft Size of 76.20 mm, a Bore Size of 101.60 mm, and a Width Size of 15.88 mm.
