The basic construction of flexible couplings consists of two flanges or hubs, which attach to the shafts being coupled and a connecting element that may be metallic, such as in disc couplings; it may also be a sleeve made from elastomeric material, such as EPDM rubber, neoprene, Hytrel or urethane, or it may be mechanical as in a u-joint or gear coupling.
