A pneumatic cylinder plug has an annular body, an axial through hole, an inside flange, an outside flange, an air port, an inner bushing and an air gap. The through hole is defined through the annular body. The air port is formed radially through the annular body and the inside flange from the axial through hole to the outside surface of the annular body. The inner bushing is formed inside the inner flange and has an inner diameter. The pneumatic cylinder plug is used with a closed pneumatic device to further support a piston rod in the closed pneumatic device.
