description The invention relates to a special pressure head for the hydrostatic testing of a gas cylinder. The special pressure head is characterized by comprising a hollow pipe-shaped central rod sleeving in a sleeve in a sliding manner, wherein a nut is fixedly mounted at the lower end of the central rod, and the central rod between the sleeve and the nut is sleeved with an elastic seal ring and a gasket; the upper end of the sleeve is connected to the lower end of a connecting body, the lower end of a cylinder body of a gas cylinder is fixedly connected to the upper end of the connecting body, and a connecting rod is fixedly connected to the upper end of the cylinder body of the gas cylinder; a groove extending to the upper end of the connecting body is formed in one side of a barrel of the connecting body; and one end of a horizontally-arranged high-pressure connecting rod penetrates through the groove of the connecting body and is fixedly connected to the upper end of the central rod, the high-pressure connecting r
