  • Material selection is a critical aspect when it comes to high-pressure oil seals. Materials like polyurethane, nitrile rubber, and FKM (fluorocarbon) are often utilized due to their excellent resistance to heat, pressure, and chemical exposure. These materials ensure the seal maintains its integrity even under extreme conditions.
  • Metal cased
  • Conventional spark plugs have been the go-to choice for decades, but they come with their limitations. They can suffer from carbon buildup over time, which reduces their ability to ignite the fuel effectively. This can lead to decreased engine performance, increased fuel consumption, and even engine damage if left unchecked.
  • Type 4
  • Another critical factor is the temperature range within which the seal will operate
  • VMQ, also known as silicone, is also used for oil seals, but this is less common because the mechanical strength of VMQ is low and this material has poor wear-resistance This makes it less suitable for dynamic applications, but it can withstand fairly low and high temperatures from -60 °C to 200 °C. Many types of VMQ are also suitable for contact with pharmaceutical and food products, so VMQ is an option worth considering. VMQ oil seals are usually available on request.

  • resistance. All the polyacrylonitrile rubber and polyurethane rubber can not be used in high temperature or 
  • Shaft and Bore Tolerance

  • Pressure: As the pressure increases, the radial load and the friction of the sealing lip increase in contact with the shaft. As with temperature, each oil seal has a recommended pressure for optimum performance. Excessive pressure causes the seals to wear more quickly and consequently have a shorter life.
  • In conclusion, small oil seals may be tiny in stature but their impact on machinery and the broader environment is immense. By understanding their function and importance, and by providing adequate maintenance, we can ensure that these unsung heroes continue to protect our machinery and the environment from the detrimental effects of oil leakage. As we move forward in the realm of mechanical innovation, it is essential not to overlook the significance of these small yet mighty components that safeguard the very heart of our machines.
  • One of the key attributes of the A7TJC spark plug is its ability to deliver a robust and reliable spark. This is made possible by its platinum or iridium center electrode, which not only enhances durability but also improves ignitability. These precious metals have higher melting points and superior electrical conductivity, ensuring a longer lifespan and reduced maintenance requirements.
