The present invention is a pressurized gas inflation device for inflating an inflatable article of manufacture. In the preferred embodiment, the device includes a cylindrical housing which receives a cartridge of pressurized gas, a head unit and a nozzle. The head unit includes a valve assembly for controlling the flow of gas through the device. The nozzle includes a means for controlling the flow rate of the gas flowing through the nozzle and a means for relieving the build-up of excess pressure. The nozzle of the device may be structured to couple in a fluid-tight manner with an adaptor of an inflation valve. The adaptor of the present invention includes a top surface, at least one side wall and several apertures for receiving fluid from an inflation device or for venting fluid from a bladder.
