Introduction to Orings and Seals
Orings and seals are essential components in various industries, playing a crucial role in preventing the leakage of fluids and gases. Orings are circular seals made of elastomeric materials such as rubber, silicone, or fluorocarbon. They are commonly used in hydraulic systems, pneumatic systems, and automotive engines to create a tight seal between two mating surfaces. Seals, on the other hand, are more general terms that refer to any device used to prevent the passage of fluids or gases. They can be made of different materials and have various shapes and sizes depending on the specific application. Orings and Seals
