Conclusion
The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s.
- In electronics and electrical equipment, thin rubber gaskets are used to seal enclosures, control panels, and connectors. They protect sensitive components from dust, moisture, and other contaminants, ensuring the reliability and longevity of the equipment. These gaskets are often made from conductive rubber materials to provide electromagnetic interference (EMI) shielding and grounding.
Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.

- In the world of industrial machinery and engineering, metallic oil seals play a pivotal role in ensuring the efficient and safe operation of various systems. These seals, also known as metallic mechanical seals, are designed to prevent the leakage of lubricants or other fluids, thus maintaining the integrity of the machinery and prolonging its lifespan.
- A typical spark plug consists of a ceramic insulator, a central electrode, and a ground electrode. When an electric current is passed through the plug, it creates a high voltage arc between the central and ground electrodes. This arc ionizes the air-fuel mixture, creating a plasma that rapidly expands and pushes the piston down the cylinder, generating mechanical energy.
The main lip is the most critical component of the seal.
Its sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)Double Lips - The process of creating a rubber tube gasket involves precise molding, cutting, or extrusion techniques to ensure the final product fits perfectly onto the pipe or tube surface. The gasket's design, thickness, and material selection all play crucial roles in determining its performance and longevity. Engineers often rely on computer-aided design (CAD) software to create intricate gasket profiles that can handle complex geometries and ensure optimal sealing.

- It's also worth mentioning that certain high-performance or specialty vehicles may require iridium spark plugs to meet manufacturer specifications. In such cases, the choice is not merely about cost but also about maintaining the integrity of the engine and warranties.
- The failure of an oil seal can result in oil leaks, which not only waste valuable lubricant but also pose environmental risks. Moreover, the absence of a proper seal can allow dirt and other debris to infiltrate the system, causing accelerated wear on moving parts. In some cases, the loss of lubrication can cause overheating and potentially lead to fires or explosions, especially in high-pressure applications.

6. AMOUNT OF LUBRICANT: Seals perform better when lubricated but some machines will go through some dry spells. When this occurs using a leather or PTFE seal will be more beneficial as those type of seals can operate with less lubrication.
This technique involves aligning the installation tool with the face of the shaft to precisely position the seal. Double-checking alignment after installation is essential to avoid future misalignment issues.
