Variety of Oil Seals
Despite being incredibly flexible, silicone has some significant drawbacks. The toughness, resistance to wear, and abrasion of many silicone compounds are poor. If you seriously need an oil seal material with better strength and resistance to high temperature, the perfect option is Viton.


Based on the application of the oil seal, the outer skin layer tends to differ. Here are some types of the materials used for the outer skin of the oil seal.
Wipe the head and block absolutely clean with a cloth moistened with petrol.
High carbon steel wire
(JIS* SWB)
Provide the shaft with a ramped edge
The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:
All are fitted with a spring to preload the sealing lip. All these types are for non-pressurised or low-pressure applications up to 0.5 bar for diameters of a limited size. For diameter of 500 mm or more, the maximum pressure is 0.1 bar. For higher pressures, special types or PTFE lip seals can be used.

auto spark plug. Regular inspections can help identify any potential issues, such as fouling or wear, and address them before they lead to more serious problems. It is also essential to replace your spark plugs at the recommended intervals, typically every 30,000 to 100,000 miles, depending on the type of spark plug and driving conditions.
