The cleaning bottle with manometer can be used universally, as it is suitable for introducing liquids (washing liquid, oil, UV liquid) into industrial, household and car air conditioning systems. The liquid filled in the bottle can be pressed out by applying external pressure to the connection on the device from the side of the lever tap. Thanks to the manometer on the outlet side of the bottle, the pressure of the system connected to the bottle can be measured. The hose included in the set, fitted with a needle valve pusher on one side, can be used for connection to needle valves, while the cleaning unit can also be connected to unthreaded pipes thanks to the gun with a rubber end. The cleaning kit can also be adapted to car systems thanks to the adapter.
