Abstract
A valve seal removal tool includes: an elongated, threaded rod having a stopper mounted at a proximal end of the rod and a collet connected to a distal end of the rod having an inner circumference capable of being fitted over an outer circumference of a valve seal; a collet holder movable along the longitudinal axis of the rod, and having an inner circumference capable of being fitted over an outer circumference of a proximal end of the collet; a threaded nut coupled to the rod; and a slide hammer slidable along the rod and having a proximal end that opposes the stopper and is operable to slidably contact the stopper. Tightening the nut in a distal direction of the rod causes the nut to contact the collet holder, forcing the collet holder to move over a portion of the collet which compresses the collet.
