  • Oil seals play a vital role in the efficient operation of machinery and equipment by preventing the leakage of oil or other fluids. One commonly used type of oil seal is the 65x90x10 oil seal, which is designed to fit a specific shaft size of 65mm, an outer diameter of 90mm, and a thickness of 10mm. These seals are typically made from rubber or other flexible materials that can withstand the harsh conditions often found in machinery.


  • The SSR 125 spark plug is tailored for motorcycles, particularly the SSR 125 model, which is renowned for its agility and speed. Its design is centered around the principle of delivering a robust and reliable ignition source, translating into enhanced engine responsiveness and improved fuel economy. With a 125cc displacement, the SSR 125 motorcycle demands a spark plug that can handle the intensity of its power output, and the SSR 125 spark plug fits this bill perfectly.
  • 2. Aerospace industry High temperature rubber gaskets are used in aircraft engines, fuel systems, and air conditioning systems to ensure sealing under extreme conditions.

  • Over time, piston oil seals may wear out or become damaged due to normal wear and tear, extreme temperatures, or poor maintenance practices. When this happens, oil leakage can occur, leading to decreased engine performance and potential damage to the engine.


  • In conclusion, spark plug wires, though seemingly small, are integral to the functioning of an internal combustion engine. They serve as the conduit for the spark that ignites the fuel, propelling the vehicle forward. Understanding their importance and ensuring their proper maintenance can greatly contribute to the longevity and efficiency of any vehicle.

  • To replace a motor oil seal, it is necessary to disassemble the engine and carefully remove the old seal before installing a new one. This process requires precision and attention to detail to ensure that the new seal is properly seated and sealed within the engine. It is also important to use the correct type of seal for the specific make and model of the vehicle to ensure a proper fit and seal.
  • (6) Note that there should be a certain amount of lubricating oil on the lip of the oil seal.

  • 5. Set the spark plug gap Use the spark plug gap tool to set the correct gap between the center electrode and ground electrode of the plug.
  • The most common oil seals are the ERIKS types R, RST, M and MST, which correspond respectively to types A, AS, B and BS according to DIN 3760/ISO 6194.
