In addition to material compatibility, the design and installation of aircraft structural fasteners are also critical factors in ensuring the integrity of the aircraft. Fasteners must be properly torqued to the manufacturer's specifications to ensure that they provide the necessary clamping force to hold parts together securely Fasteners must be properly torqued to the manufacturer's specifications to ensure that they provide the necessary clamping force to hold parts together securely
Viton Oil Seals - A synthetic rubber and fluoropolymer elastomer, Viton is used to make oil seals that provide resistance in both high temperature, up to 250°C and low compression set components. They also offer a high resistance to chemicals and abrasions, so they can be used in elements that regularly interact with petroleum and solvents.

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.
When deciding on the best type of seal for a particular application, it is best to consider all aspects of the environment and its purpose. If the application requires a spring- loaded seal, that does not eliminate either the rotary shaft seal or the mechanical seal. If the equipment is operating in extreme temperatures, including situations where the rapid movement of the equipment creates extreme heat, a mechanical seal will hold up better than an oil seal.

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.
A) Shaft runout
As shown in Figure 8, shaft runout is defined as being twice the eccentricity between the shaft center and center of shaft-center rotation trajectory.
