TRANSFER CASE OIL SEAL. The transfer case oil seal is a sealing component of the vehicle drivetrain designed to ensure tight sealing at the points where shafts pass through the transfer case housing. The main function of this component is to prevent transmission oil leakage from the transfer case and to protect internal parts of the assembly from dust, moisture, dirt and road contaminants. Reliable seal operation helps maintain the proper lubricant level inside the unit, reduces wear of gears, bearings and other drivetrain components and ensures stable and long‑term operation of the vehicle’s all‑wheel‑drive system. The seal is manufactured from high‑quality wear‑resistant and oil‑resistant elastomer materials that withstand the effects of transmission oils, temperature fluctuations, vibrations and mechanical loads. Its design ensures a tight fit against the shaft surface and the housing seat, providing effective sealing and reliable protection of the assembly during vehicle operation in various road and climate conditions. The catalog includes transfer case oil seals for various passenger cars, sport utility vehicles and commercial vehicles. Selection is carried out according to the drivetrain design and manufacturer specifications.
