Silicone
Wide temperature range
Commonly used in low temperature applications
Very prone to mechanical damage during fittingIn addition to size and material, the design and construction of the oil seal are also crucial factors to consider. The 65x90x10 oil seal is typically constructed with a metal casing, a rubber sealing lip, and a spring for added tension. This design helps to create a tight seal and prevent oil from leaking out, even under high pressures and temperatures.

High level of chemical resistance
High temperature resistanceRaise the front of the car on ramps, apply the handbrake and chock the rear wheels. Clean round the sump and the crankcase , clutch and gearbox. Drain the engine oil (See How to drain engine oil and remove filter ). Use an adequate jack to lift the engine.
Oil Gasket Seal:
The hydrodynamic ribsa) provided in one direction on the air side face of the lip ensure higher sealing performance. Perfect Seal The hydrodynamic ribsa) provided in two directions on the air side face of the lip ensure higher sealing performance (higher sealing performance in both rotational directions of the shaft).
A shaft’s surface finishing will determine how effective the sealing will be. The spiral lead and the direction of the finish tool marks have an impact on the sealing effectiveness. Therefore, it’s imperative to ensure that the shaft surface finishing is maintained.
Car Iridium Spark Plug: Advantages and Performance
Metal O.D. wall - Polyurethane (PU): Polyurethane seals offer excellent abrasion resistance and durability. They are suitable for high-pressure applications and provide good resistance to hydraulic oils. Polyurethane oil seals are often used in hydraulic and pneumatic systems.
This represents a new generation of oil seals.

Without minor lip
The rubber material used in the oil seal should be selected based on the operational temperature and substance to be sealed.
Table 5 lists the major rubber materials along with their operational temperature ranges.
Note that it is necessary to check the compatibility with fluids.
<N.B.>
Extreme pressure additives are compounds added to the lubricant. They are activated by heat and chemically react against rubber, which deteriorates rubber properties. For this reason, it is necessary to check for compatibility with rubber materials.
