ARB tire pressure gauge with quick release function, display BAR / PSI, 0-4 Bar

A really clever new accessory from ARB is the tire pressure gauge with quick release function, which makes it easy to lower the air pressure for off-road use.

And this is how it works:
First, the brass cap is placed on the valve, and then the valve core is unscrewed – this way, it can't be lost. The desired tire pressure is then set using a slide valve. This is very precise, as the tire pressure can be read on the pressure gauge. Then, screw the valve core back in, and you're done!
