How to Choose the Right Oil Seal
- The Versatile 20mm Rubber Gasket
- The design of oil seals is also crucial to their performance. Factors such as the seal's geometry, material selection, and the use of additional components like springs or backup rings can significantly impact its ability to contain oil and prevent leaks. Engineers must carefully consider these factors when designing oil seals to ensure they meet the rigorous demands of industrial machinery.
A standard oil seal consists of an outer circular metal disk with an inner flexible rubber which is affixed to the metal during vulcanization. The bonded seal has no loose parts to allow leakage of oil or ingress of any contaminants. This kind of seal is more accurate, and can easily be fitted into a smaller space. An example is shown in Figure 2.9.
- A valve cover gasket, particularly the one designed for the 4.6 engine, serves as a seal between the valve cover and the cylinder head. The 4.6 refers to the engine displacement, a measure of the engine's size, which can vary from vehicle to vehicle. This specific gasket is engineered to fit the unique specifications of engines with this displacement, providing a tight seal to prevent oil leaks and maintain internal pressure.

Purpose of oil seal
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)
EPDM oil seals are less common. They are used in solvent, hot water and steam applications, EPDM resists low temperatures down to -50 °C and UV radiation well. Some types of EPDM are also suitable for higher temperatures up to +150 °C. EPDM oil seals are usually available upon request.
