An O-ring is a round ring that is used as a gasket for sealing a connection. O-rings are typically constructed out of polyurethane, silicone, neoprene, nitrile rubber or fluorocarbon. These rings are commonly used in mechanical applications, such as pipe connections, and help to ensure a tight seal between two objects.
1 Rubber O-rings are made of rubber and synthetic rubber materials. 2  Silicone O-rings are made of a material that is commonly used in hot air applications as well as devices in the medical field. 3  The silicon-oxygen structure gives silicone o-rings good thermal stability. 4  are gaskets used in static joints. Nitrile O-rings are by far the most popular type of seal material used in the world. 2  Nitrile o-rings are carbon triple-bonded to nitrogen, which provides good resistance to oils and fuels. 3  O-ring kits are sets of o-rings that are designed to replace faulty o-rings.
