Combination Tire Valve Core Removal and Fluid Fill Tool
A tool attachable to a valve stem of a tire grips and removes the valve core from the valve stem prior to introduction of sealant through the tool into the tire. Subsequently, the valve core, which has been stored in the tool, may be reinserted into the valve stem. An external pressurized gas source may then be attached to the tool so that gas may be injected through the tool and the valve stem of the tire into the tire.

10 . In combination, a universal coupler for receiving a plug and a plug for selective locking engagement to said universal coupler on a first end thereof and to a pneumatic tool or hose on a second end thereof, said plug having a forward land and groove configured on its outer surface, said universal coupler having a body member including a generally constant diameter throughbore with an outwardly extending flange and an inwardly extending flange both at said plug receiving end, said body member further including a set of passages adjacent said plug receiving end and displaceable ball bearing retention members located in said passages, a retainer nut attached to the body member at the opposite end of the plug receiving end, the nut including an internal through passageway with an external land, a valve member slidably retained within said constant diameter throughbore being limited in movement axially toward said plug receiving end by a flange, said valve member being biased toward said plug receiving end, a sleeve configured about a portion of said body member biased away from said plug receiving end, said valve member and sleeve constituting said ball bearing retention members for retaining a plurality of ball bearings, ball bearings located proximate said outwardly extending flange, said throughbore further comprising a seal being retained by a lip wherein said forward land is sized such that upon insertion of said second end of said plug into said plug receiving end of said universal coupler, said valve member is caused to move axially against said bias and said ball bearings are cause to seat within said groove whereupon said sleeve is caused to move toward said plug receiving end for selectively and lockably attaching said plug to said coupler.
11 . The combination of claim 10 wherein said sleeve is sized to be grasped by a user and moved axially away from said plug receiving end for selective removal of said plug from said universal coupler.
