ABSTRACT:
An expander tool such as for use in removing tubing from barbed fittings. The tool includes a pair of handle members having a pivotal connection therebetween. A pair of channel-shaped jaw members are operatively connected to the handle members for spreading movement in a generally parallel direction when the handle members are moved toward each other. The channel-shaped jaw members are nested with the bight portions thereof being thin and flat and in generally parallel confronting relation. The legs of the channel-shaped jaw members therefore are in overlapped relation whereby the opposite side of the thin flat bight portion of one jaw member can be positioned in close proximity to a workpiece such as the flange or elbow of a barbed fitting. The thin flat bight portions of the jaw members have slots opening outwardly of the tool, the slots each having a stepped configuration for embracing different sizes of workpieces, such as different diameters of tubing and barbed fittings.
