A valve core gripper can be coupled to the distal end of the shaft and can include a first valve core engaging surface and an opposing second valve core engaging surface spaced therefrom. The first and second valve core engaging surfaces can be flexible and movable relative to each other between a first position, where the free ends of the first and second valve core engaging surfaces are spaced apart a first distance, and a second position, where the free ends of the first and second valve core engaging surfaces are spaced apart a second distance that is greater than the first distance. The first and second valve core engaging surfaces can be spring-biased in the first position for gripping a valve core between the first and second valve core engaging surfaces. ## Claims ### Claim 1 A valve core removal tool comprising: an elongated shaft comprising a proximal end, a distal end, and an outer surface, the elongated shaft extending along a longitudinal axis thereof between the proximal end and the distal end, the outer surface extending between the proximal end and the distal end;
