A tire inflator gun is an indispensable air tool in every car workshop. If the workshop has a compressor then you should have this very cheap and practical tool. Pneumatic line connection can be done with or without quick-connect fitting. When is for free use, then it is better to have it without a quick-connect fitting to prevent the theft of this tool.
Some versions have a mechanism that allows the top of the hose to be attached to the tire valve. You should drink with caution when using this mechanism, because due to the carelessness of the operator, the tire may inflate and burst. The tire inflation gun must also contain a pressure gauge (manometer) that measures the pressure in the tires. During inflating without a manometer, we cannot determine the tire pressure prescribed by the vehicle manufacturer. On the manometer, there are usually two scales for measuring pressure, expressed in units of bar and psi.
