The flexibility of rubber allows these gaskets to absorb vibrations and shocks, reducing the risk of pipe damage and ensuring a long-lasting seal.Oil seals are typically classified based on their sealing capabilities, with common types including lip seals, mechanical seals, and hydraulic seals. Lip seals are the most basic type, consisting of a flexible lip that seals against the shaft. Mechanical seals use sliding or rotating components to create a seal, while hydraulic seals are designed for high-pressure applications.
Early engines used O-rings (also called packing rings or toric joints) as seals (first patented in 1896). These are just mechanical gaskets in the shape of a torus (a circular ring--like a lifesaver), seated in a groove and compressed during assembly between two or more parts. It creates a seal at the interface. However, O-rings require a fluid film to lubricate them. They have limited usefulness in vacuum application and at extremes of temperature. The modern oil seal represents a significant improvement over the simple O-ring because it effectively seals in lubrication and prevents contamination from outside under a wide range of pressures and temperatures.
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.

O.D. (outside diameter) surface The O.D. surface affixes the oil seal to the housing and prevents leakage , through the fitting area, of substances to be sealed, while excluding contaminants.
Various materials with unique properties are utilised in the construction of rotary shaft seals, allowing manufacturers to tailor the sealing solution to specific industry requirements and ensure optimal performance.
The seal is usually made of high-quality materials such as rubber or synthetic compounds that can withstand high temperatures and pressures. It is designed to maintain a tight seal even under extreme conditions, such as rapid changes in temperature and pressure during engine operation.
