Oil seals, which are also referred to as radial shaft seals, rotary shaft seals, grease seals, or fluid seals, are used to close the gaps between fixed and moving parts of mechanical equipment. They are put between moving and stationary mechanical parts to make sure that moisture, contaminants, corrosive materials, and abrasives don’t cause any damage to these parts.

In conclusion, spark plugs are a critical component of any internal combustion engine, as they are responsible for igniting the air-fuel mixture and powering the vehicle. Regular maintenance and replacement of spark plugs are essential to ensure optimal engine performance and efficiency. By choosing the right type of spark plugs and properly installing them, vehicle owners can enjoy a smoother and more reliable driving experience.

diesel spark plugs. This ensures that the fuel-air mixture is ignited properly and that the combustion process is as efficient as possible. This is important for diesel engines, which rely on precise combustion to generate power.
Seals are classified by O.D. wall material, lip type, and whether they have a spring or not.
Major oil seals are specified in ISO 6194-1 and JIS B 2402-1.
Table 2 shows the common types of oil seals, while Table 3 shows the features of each type of oil seal.

Summary
Metal case The metal case provides rigidity to the seal, helping it settle on the housing securely. It also ensures easy seal handling and mounting.
Describe difference between mechanical seal and oil seal – Whether it is a mechanical seal or oil seal, it prevents the fluid seeping the liquid to other parts of the machine, or it keeps the rotating parts lubricated.
