Moreover, the R&D wings of these factories are at the forefront of scientific discovery

When selecting a gasket for the valve cover, it is important to consider factors such as material quality, durability, and compatibility with the specific engine model. High-quality gasket valve covers are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions that contribute to the overall performance and safety of the engine. Choosing reputable suppliers and manufacturers known for producing high-quality gasket valve covers is crucial to ensure the reliability and longevity of these critical components.
Global O-Ring and Seal’s oil seal part numbers are designed to describe the seal size, style, and material composition. When searching for oil seals via our online store, you will not only be presented with your selection but with comparable oil seals of the same dimensions. There are often viable style substitutions that are functionally compatible but with additional features. With over 50,000 unique oil seals in our database, you can cross-reference 215,000 part numbers of OEMs and Manufacturers. In the Search Bar above, simply type the OEM/manufacturer part number alone (no need to type the name), and the oil seals matching that part number will be displayed.



The most important function of an oil seal is to protect all types of sleeves, roller bearings, and balls located in the rotary shafts. These seals also prevent two fluids from mixing, such as water and oil.
Oil seals work by squeezing and retaining lubricant in a thin layer between the lip and the shaft. Perfect sealing is ensured by the hydrodynamic action of the rotating shaft, which in turn produces a slight pump action.

Regular maintenance and inspection of the oil seal are essential to ensure its continued effectiveness. Any signs of wear or damage should be addressed promptly to prevent oil leaks and potential damage to the machinery or equipment.
The basic principle of sealing is straightforward – the flexible lip is held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore and holds the seal in place. The sealing lip needs some form of lubrication to avoid overheating and is usually energized by means of a garter spring.
Assembling the oil seals is only possible with the right assembly tools. Due to the high risk of damage during assembly, it is important that you have tools with which you can work carefully. A bearing fitting tool set is ideal.

Why Is Bearing A Seal Important?

The oil seal would seal one face against a rotating member and the other face to a stationary housing. It would prevent dirt from coming between the hub or shaft and the seal.
What Benefits Do Oil Seals Provide?
Oil seals are always exposed to a lot of chemicals, both mild and harsh chemicals. The seals react by showing some signs like cracks, blisters, and discoloration especially when the chemical is harsh. This clearly shows that the chemical is not compatible with the seal, which goes as far as affecting its cross-link density (increase or decrease). When the cross-link density increases, the seal material becomes harder, but when it decreases, the seal material becomes softer.
