Another important application of cork-and-rubber is as a seal to retain lubricants in crank shaft bearings when pressure is applied, the air within cork cells is compressed, thus exerting a reverse pressure on the restraining faces. This is termed 'fight back' and is a primary requirement in all good gasket materials. Cork-and-rubber can be cut easily, and because it is strong and flexible, it can be used for making gaskets with narrow flanges. A wide variety of formulations used for making gaskets with narrow flanges. A wide variety of formulations using different types of rubber like Natural Rubber, Synthetic Rubber, Nitrile, Neoprene, EPDM Silicone and sizes of cork granuals are available to meet the industry's various requirements.Special cork-and-rubber have been developed to prevent leakage of the very searching cooling fluids used in modern electrical transformer, similar material are also widely used in switch gear circuit breakers, lightning arresters, and other transmission equipment, as well as in conduit fittings, gear cases and cover plates in washing machines.
