摘要：

<p>A hand-operated hydraulic compression tool for compressing a metal connector about a plurality of wires to be connected. The tool is adapted to make both parallel and butt-type connections of the wires. The tool includes a pressure relief valve for limiting the maximum pressure to be applied to the connector. The valve is removably installed in a two-piece housing in a cavity of the tool body for facilitated servicing. The housing is provided with a plurality of outlet passages opening to an annular recess in the housing communicating through a suitable discharge opening with a fluid reservoir. The tool further includes control structure for releasing the pressure upon completion of a forming operation, the flow passage for the returning hydraulic fluid utilizing a portion of the body cavity receiving the pressure regulating valve.</p>
