One common type of oil seal is the lip seal, which features a flexible lip that makes contact with the rotating shaft to create a tight seal. Lip seals are often used in automotive engines, gearboxes, and industrial pumps due to their effectiveness in preventing oil leaks. Another popular option is the mechanical seal, which uses a rotating element to maintain constant contact with the shaft, ensuring a reliable seal even at high speeds and pressures.
