-
Crankshaft front and rear seals
-
Camshaft seals
-
Valve stem seals
➡️ Prevent oil leakage and contamination in high-speed, high-heat environments.
2. Transmission and Gearboxes
-
Input and output shaft seals
-
Torque converter seals
➡️ Retain transmission fluid and ensure efficient power transfer.
3. Wheel and Axle Assemblies
-
Wheel hub seals
-
Differential and axle shaft seals
➡️ Protect bearings and gears from road debris and moisture.
4. Steering and Suspension
-
Power steering pump seals
-
Shock absorber seals
➡️ Ensure smooth steering and dampening functions.
5. Cooling and Pumping Systems
-
Water pump shaft seals
-
Fuel pump and oil pump seals
➡️ Maintain system pressure and prevent coolant/fuel leakage.
