-50~170 - 1. Automotive Industry Metal-to-oil seals are commonly used in engine systems, transmission systems, and hydraulic systems to prevent oil leaks and maintain fluid integrity.
- In rubber seal material, its heat resistance (decomposition temperature is greater than 400
- Secondly, OEM spark plugs contribute to improved fuel efficiency
Which option is best? This decision is left entirely to you. Whatever solution you choose, the seal needs a proper fit to function.

Unthinkable in the list of seals are oil seals, which provide a seal against splashing oil. The most important oil seals are used for rotating shafts and valve stem seals. Oil seals are intentionally never completely sealed to lubricate the seals and prevent wear.
Choosing the correct type for your application
Another factor that can affect the cost of new spark plugs is the brand. Some well-known brands in the automotive industry may charge a premium for their spark plugs due to their reputation for quality and reliability. However, there are also more affordable brands that offer reliable performance at a lower cost.
