Doubling profits would turn some non-union heads at Deublin, a leading manufacturer of rotating unions (a specialty mechanical device that allows the transmission of pressurized fluid from a stationary source into rotating machinery for heating, cooling, or the transfer of fluid power). Rotating unions are used in equipment such as air clutches, gearboxes, machine tool spindles, and rubber and plastic manufacturing machinery. The company also makes turbulence bars, siphons, and steam joints, which are sold to the automotive, machine tool, and printing industries.
