- The crankshaft oil seal is a critical component in an engine that helps to prevent oil from leaking out of the crankshaft housing. This seal is typically made of rubber or silicone and is located at the front or rear of the engine where the crankshaft exits the engine block.
- Another significant benefit of the L7TC Spark Plug is its environmental friendliness
- Metal oil seals are an essential component in machinery and automotive applications to prevent leakage and contamination of oil or other fluids. These seals are designed to create a barrier between the moving parts of the machine and the external environment, ensuring that the oil stays contained within the system.

Classical oil seals consist of a metal housing that carries the dynamic sealing lip and provides the static sealing function. These are usually manufactured of elastomer material, such as ACM, Silicone or FPM. Further, since they are in contact with the surface of the rotating shaft, the lip is pressed onto the shaft surface by means of a spring ring.
- Carbon Steel: The most common material for oil seal cases, suitable for use with standard lubricants.

- 5. Medical Devices Silicone gaskets are used in medical devices to provide a seal between moving parts and prevent contamination.
- Strong output against sand, dirt and other substances
- Now, thoroughly clean both the valve cover and the cylinder head surface with a suitable solvent to remove all old gasket material and any buildup

The oil seal would seal one face against a rotating member and the other face to a stationary housing. It would prevent dirt from coming between the hub or shaft and the seal.
Conventional oil seals are the traditional seals, which can be recognised by a spring on the inside. These oil seals are made of a metal housing that contains a rubber seal. This part is often made of elastomer and comes into contact with the surface of the rotating shaft.


Rubber gaskets, commonly used in various industrial applications, serve the purpose of preventing oil leakage and maintaining the integrity of machinery by creating a barrier between two or more components.
