An oil pulse / impulse tool is a hand held tool with a hydraulic pulse unit integrated to control output torque without reaction or high noise levels. Improvement over impact wrench -- better torque control, more durable, more ergonomic (less vibration), less noisy. Choice of Auto shut off and non shut off.
Wide range of torque capacity Pistol type (5 - 450Nm) Straight type (5 - 47Nm) Angle type (8.5 - 60Nm) 'Double Sealing' (Dupas"s own spec) allows better sealing in the chamber 'Accumulator' (patent pending) is an extra space in the pulse unit that allows oil to expand due to heat. This prolongs the lifetime of the oil.
