Abstract
A hand-held tool for straightening tubing such as brake fluid lines in vehicles, the tool provides a housing having an outer covering, internally thereof, a series of sets of rollers, that are adjustable radially, supported by end frames, and intermediate the rollers and the outer covering is an adjuster ring, shiftable longitudinally within the housing, operatively associated with the rollers, such that when the adjuster ring is pulled outwardly, longitudinally, from the tool housing, the rollers shift radially outwardly, for accommodating larger tubing, and when the adjuster ring is pushed inwardly of the housing, the rollers are forced inwardly against smaller diameter tubing, in preparation for its straightening. A sector of the tool, usually along a quadrant, is opened from one end to the other of the tool, so as to allow the tool to be applied to the tubing to be straightened, anywhere along its length, and not only at its ends.
