A compression tool for compressing a generally tubular workpiece, comprises a tool head having an open, workpiece-receiving end. A plurality of generally parallel, spaced apart movable compressing members are carried by the tool head. A stationary compression surface also carried by the tool head opposingly faces the movable compressing members. Guides are provided in the tool head for slidably mounting the movable compressing members. A ram drives the movable compressing members towards their respective maximum compressed positions, which are defined by the ram and a ram-carrying channel. This maximum compressed position generally increases in a predetermined sequence from the workpiece-receiving end of the tool head toward an interior portion of the tool head.
