(This prevents failure during mounting.)
Seals with an auxiliary, contacting lip can also be filled with grease between the sealing lip and auxiliary lip to reduce frictional moment. This does not apply to silicone rubber seals and seals with hydrodynamic features, other than WAVE lip designs. also recommends using a hydraulic press, with suitable tools, to install a seal in its housing bore. Pressure should be applied as close as possible to the outside diameter of the seal.” Oil seals are commonly used in a variety of industries. Below are 5 types of oil seals used in today’s manufacturing and machinery industry.
Fluid Types - Various oil seals are able to withstand interactions with oils, fuels, grease, water and more. Knowing what type of fluid the rotary shaft seal will be in constant contact with will ensure the longevity of the seal and surrounding components.

Oil seals, also referred to as shaft seals, are widely used to prevent the leakage of medium (such as oils and grease) along a rotating shaft. This leak prevention is primarily achieved by the sealing element which can be made from a wide range of materials that are chosen according to each application. They are commonly used in gearboxes, hydraulic cylinders, and related components.

4. The sealing function of the oil seal is good and the service life is long. It has the certain adaptability to the vibration of the machine and eccentricity of the main shaft.
White rubber gasket sheets are widely utilized for their adaptability and sealing properties. These sheets are commonly used in applications where a durable and flexible sealing solution is required. The white rubber material offers resistance to heat, chemicals, and weathering, making it suitable for diverse industrial and commercial applications. The sheets can be custom-cut to fit specific requirements, providing a versatile and effective sealing solution.
The valve cover gasket and spark plugs are integral components in the engine's ignition system. The valve cover gasket seals the valve cover to prevent oil leaks, while the spark plugs play a crucial role in igniting the air-fuel mixture within the combustion chambers. Proper sealing provided by the valve cover gasket is essential for maintaining the integrity of the engine, while reliable spark plugs contribute to efficient ignition and combustion, ensuring optimal engine performance.
Select the correct oil seal size
Never use a used seal in another project as it may develop defects such as cracks or bubbles in the seal lip previously used.
