Claims6
A valve stem removal and insertion kit comprising the following:
- a. a valve stem insertion tool comprising a rod having a T-shaped handle at one end and bearing at its opposite end means for removably attaching the threaded tube of a valve stem;
- b. a valve stem insertion sleeve for receiving said rod in a reciprocal relationship thereto, having at one of its ends an internal cross-section conforming to the shape and at least equal to the cross-sectional area of the unconfined bulbous end of the valve stem, at its opposite end an external cross-section conforming to the shape and slightly lesser than the area of the hole in the rim of the wheel, smoothly tapered interior wall extending between the ends thereof and terminating in an internal cross-section which is less than the cross-section of the hole in the rim of the wheel to facilitate compression and insertion of the bulbous end of a valve stem into the hole of the rim;
- and
- c. a valve stem removal tool comprising a rod having a T-shaped handle at one end and bearing at its opposite end a “J”-shaped curve, and the short side of the “J” comprising a blunt end of sufficient length and spaced apart from the rod such as to facilitate insertion into the interior opening of the bulbous end of a tire valve stem, and having sufficient curvature so as to facilitate insertion of the blunt end of the valve removal tool into the opening at the bulbous end of the tire valve and engage the opening in the valve stem which is in the interior of the wheel and thereby facilitates the removal of a valve stem from a wall of a tire.
