ABSTRACT:
A portable tool for crimping a ferrel portion of a tube fitting around a hose is provided. The tool has an upper and lower frame. The upper frame has a means for stabilizing an upper die carrier which encloses an upper die insert. The lower frame encloses a lower die insert. A compression shaft is inserted through an aperture formed in the upper frame for moving the upper die carrier along a vertical axis of the tool. A means for pivoting the upper frame in relation to the lower frame is provided to allow a user to open and close the tool. A locking means is further provided permitting the upper frame to be locked to the lower frame during a crimping procedure. The compression shaft can be actuated manually, electrically, or hydraulically. The tool may further be set into a framed housing for use in a manufacturing environment.
