Comprehensive Guide to O-Rings: Types, Features, and Manufacturers
O-rings have got their name because of their circular cross-section. They act as essential sealants by providing a protective layer between the components. They prevent leakage, thus not allowing a liquid or a gas to escape. Due to their versatility, you can use them both for static and dynamic applications.
Understanding O-Rings
O-rings are one of the most widely used sealing elements in various industries, including automotive, aerospace, and manufacturing. They are designed to prevent the escape of fluids and gases, ensuring the integrity of mechanical systems. The effectiveness of an O-ring depends on its material, size, and the conditions under which it operates.
