  • 4. Ozone resistance High temperature rubber gaskets are also resistant to ozone, which is a common byproduct of electrical discharges. This property makes them suitable for use in environments where ozone is present.
  • Oil seals are essential components in various machinery and equipment, providing a critical barrier between the moving parts and the external environment. One such seal is the Oil Seal 20/34/7, which has gained popularity due to its exceptional performance and durability. In this article, we will delve into the features, benefits, and applications of the Oil Seal 20/34/7.
  • When considering the importance of oil in machinery, the role of the 12x22x5 oil seal becomes even more evident12x22x5 oil seal. Oil is the lifeblood of many systems, lubricating moving parts to reduce friction and wear, dissipating heat, and protecting against corrosion. However, without proper containment, oil can become a liability, leaking into places it shouldn’t and potentially causing damage or reducing efficiency.

  • Rotary shaft or oil seals are placed between moving and stationary pieces of machinery to ensure that contaminants, moisture, corrosive materials and abrasives do not damage the various components. They can also prevent unwanted mixing of fluids, including water and oil combining within a machine.

  • There are several benefits to using lip seal gaskets in various applications
  •  

  • Leather 
    Recommended for abrasive applications 
    Good running properties, due to the impregnated seal lip 
    Can be used on shafts which have a surface roughness outside the range for rubber seals 
    Not suitable for water

  • 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.

  • Oil seals are a crucial component in any high-pressure system, serving the important role of preventing leaks and maintaining the integrity of the system. These seals are designed to withstand the high pressures typically found in hydraulic systems, engines, compressors, and other machinery where oil leakage can cause serious damage.


  • However, rubber gaskets do have their limitations. They can be prone to (aging) and degradation when exposed to extreme temperatures, UV radiation, or certain chemicals. To address these issues, manufacturers often use additives or coatings to enhance the durability and performance of rubber gaskets.
  • A loose or missing valve cover gasket bolt can lead to a variety of issues. An oil leak can contaminate the spark plugs, affect the air-fuel ratio, and lead to misfires. Moreover, leaked oil can pool on hot engine parts, posing a fire hazard Moreover, leaked oil can pool on hot engine parts, posing a fire hazard Moreover, leaked oil can pool on hot engine parts, posing a fire hazard Moreover, leaked oil can pool on hot engine parts, posing a fire hazardvalve cover gasket bolts. Conversely, overtightening the bolts can strip their threads or crack the valve cover, necessitating costly repairs.
