The durometer of an oil seal is typically dependent on the material it is made with. Common oil seal materials along with their durometers are as follows:
In conclusion, high pressure oil seals are the unsung heroes of many industrial processes. Their ability to withstand intense pressure and maintain system integrity is fundamental to the smooth operation of machinery. As technology continues to evolve, so too will these seals, providing more efficient and reliable solutions for a wide range of applications. Whether it's a complex hydraulic system or a high-performance engine, the role of high pressure oil seals cannot be overstated.If the gap is larger than 0.002 in. (0.05 mm) at any point, have the head or block checked and machined flat by a specialist.

In addition to their sealing and durability properties, natural rubber gaskets also offer excellent resistance to a wide range of chemicals, including oils, solvents, and acids
. This makes them suitable for use in harsh industrial environments where exposure to corrosive substances is common.When the engine is running, the ignition coil receives a signal from the engine control unit to fire at the correct time. The coil then rapidly builds up a magnetic field within the primary winding when the signal is received, and when the signal is cut off, the magnetic field collapses rapidly, inducing a high voltage in the secondary winding. This high voltage is then sent to the spark plug, where it jumps the electrode gap, igniting the air-fuel mixture in the combustion chamber.
PTFE, which is used in the well-known brand Teflon®, is less commonly used, but it is the preferred material for specific rotating seals in the chemical, food and pharmaceutical industries. This material is notable for having a very low frictional resistance and the best chemical resistance. It can also withstand a very wide range of temperatures in these types of seals; -80 ˚C to 200 ˚C. The shafts on which oil seals with PTFE lips are used require a harder and finer finish. Something like an axle sleeve can also be used to meet this requirement.

There are a variety of oil seals used in a variety of applications to help close the space between a stationary and a moving part. By closing the space it prevents any lubricants from escaping. Additionally, oil seals help create a seal that prevents any contaminants from entering machinery which can cause a host of problems. Mechanical equipment and machinery require different size or type oil seals to ensure that there is a superior and precise seal. Because oil seals help reduce contamination or mixing of materials it prolongs the life of machinery and helps ensure a more reliable performance.
