Morse_Taper_Torque_Limiter_CouplingCommonly used to open and close gate valves in water treatment and irrigation systems, this friction torque limiter coupling connects to a power drill with a #3 Morse taper socket.  A variety of output options are available including different sized squares and keyed bores.   The coupling is pre-set at the factory to a torque value you specify and may be adjusted in the field if needed.  When the torque setting is exceeded, the coupling slips to prevent over tightening.
