O-Rings are an integral component in most industrial and mechanical systems. Because O-ring material selection is driven by an industrial or mechanical system, that system will define which material is best suited to fulfill the application requirements of the O-Ring. Therefore, the best O-Ring material is the material best-suited for the application. Today, the familiar donut-shaped gasket is used in a variety of static or dynamic applications and is one of the most common seals used in machinery throughout the world.
The O-Ring is very much an indispensable component. Any mechanical system whose parts requires fluids, oils, or like lubrication to function also requires gaskets such as O-Rings. Gaskets act as seals when compressed between surfaces. The seals do just that—they join mechanisms together within a mechanical device and prevent leakage or spills from seeping out of the device. They are the most widely used sealing product. With the further development of elastic polymer materials, O-Rings are utilized in nearly any mechanical application under any environmental condition or temperature, with exceptional chemical compatibility.
When O-Ring failure does happen, it may be a result of such factors as improper installation, lubrication, or incorrect size. Above all, selecting the wrong material for the application can greatly contribute to product failure. O-Rings are made through a number of manufacturing techniques such as injection or compression molding, or extrusion, with a number of elastomeric materials.
