A hydraulic tool for crimping connectors to electrical power lines includes a C-shaped crimping head which is infinitely rotatable with respect to the main body of the hydraulic tool for ease of positioning the tool with respect to workpieces. The invention particularly relates to the means for having a C-shaped head on the tool to achieve universal rotation while maintaining integrity of the hydraulic system across the rotational interface.
