A fluid coupling, also known as hydraulic coupling, is a hydrodynamic device used in automobile transmissions as an alternative to the mechanical clutch to transmit rotating mechanical power. Apart from cars, fluid couplings also have widespread applications in marine and industrial machine drives, where they provide shock-free start-up for the power transmission system. At BSC, we have a wide range of fluid couplings for all your requirements. Our TRANSFLUID brand couplings include KX fluid couplings, K-CK-CCK fluid couplings, KPTO variable fill fluid couplings, KSL variable fill fluid couplings, oil actuated power take off and more.
