Abstract: An improved shaft safety pneumatic valve system in combination with a pneumatic expanding core shaft, is provided. The valve system provides a threaded air valve with a disk threadingly engaging the threaded air valve and a corresponding adapter fitted onto an air gun and adapted to engage the threaded air valve via the threaded disk. The threaded disk acts as a shroud about the air valve preventing an operator's finger from entering the bearing tube aperture to release air from the air valve.
