- The 'U' shape of the gasket is not just a design choice; it serves a functional purpose. The three-sided structure enables it to create a tight seal around the circumference of a joining surface, ensuring a secure closure against liquids, gases, or other elements. This design also allows for compression, which enhances the sealing ability when pressure is applied during assembly.
• Rotational speed, etc. - fluoro-rubber oil seals are used in drilling machinery, refining equipment, and natural gas desulfurization
When it comes to maintaining the performance of your vehicle, one of the most important components to consider is the spark plug. The spark plug plays a crucial role in igniting the air-fuel mixture in your engine's combustion chamber, which in turn powers your vehicle.

Garter springs are generally used when the lubricant is oil, as it provides the necessary downward force to maintain a tight seal. However, when grease is the lubricant, garter springs can often be eliminated. Due to its low viscosity, grease doesn’t require as much downward force to maintain an effective seal.




These cassette seals are widely used in wheel-end applications, such as the axles of agricultural machinery or off-road trucks.
