ABSTRACT:
A reaction system for use in combination with a fluid-powered wrench tool in assembling or disassembling large size tube fittings of a variety including a fastener or nut which is threadably engagable with a port end of the fitting body. The system includes a reaction member attachable to the tool as extending along a central longitudinal axis disposed general parallel to the line of action of the cylinder assembly of the tool from a forward end face positionable in confrontation with the fastener to an opposite rearward end face. The system also includes an associated wrench member which is provided as having a rearward shank end mountable to the reaction member and a forward jaw end configured to receive the external surface of the fitting body in an engagement which delimits the rotation of the fitting body in a first direction about the axis of rotation of the fitting fastener.
