ABSTRACT:
A fluid valve can be disconnected from a fluid pressurized container by use of a changer tool having an elongated tubular housing, a tubular member positioned within and coaxial with the housing bore for slidable movement along the longitudinal axis, a shaft positioned within and coaxial with the bore of the tubular member for axial movement of the shaft with respect to the tubular member, a first retention member on one end of the shaft, a second retention member on one end of the tubular member, and an elastomeric tubular plug member positioned about the shaft between and in contact with the two retention members. Each of the two end portions of the elastomeric plug member is substantially harder than the intermediate portion of the elastomeric plug member, and is provided with an outwardly extending annular ring which engages an internal shoulder in the associated retention member to secure the retention member to the plug member.
