- Environmental Factors: Consider external factors such as exposure to dirt, water, and other contaminants, temperature fluctuations, chemical exposure, and shaft speed. For example, oil seals that must withstand high-speed rotational motion, high-pressure conditions, or extreme temperatures require more durable and resilient materials.
- An oil seal's primary function is to create a barrier between lubricants and the external environment. It is designed to withstand the rigors of heat, pressure, and physical motion, all while keeping oil in and water, dust, and other pollutants out. The effectiveness of these seals is paramount; a failure can lead to oil leaks, reduced lubrication, increased wear and tear on moving parts, and ultimately, catastrophic equipment failure.
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.- When placed in a modern oil well with a

- Oil seals comprise three core components – the sealing element (or lip), the metal case, and the optional garter spring, each contributing to the seal’s functionality and effectiveness.

The purpose of the oil seals is
- In addition to preventing oil leaks, valve oil seals also help to regulate the amount of oil that enters the combustion chamber
valve oil seal. Excessive oil in the combustion chamber can lead to fouled spark plugs, increased emissions, and reduced engine performance. By controlling the flow of oil into the combustion chamber, valve oil seals help to maintain optimal engine function.
The metal used in the outer case of oil seals is usually made of carbon steel. Upon request, and depending on quantities, a different type of steel (such as stainless steel) can be used.

different types of spark plugs.
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.
