Reduces noises during deflating tires (car, truck, bus). Removing the valve one handed and the valve does not get lost.
If the air flows out of a tire there is a loud noise, which can easily reach up to 115db (that is comparable to the noise of a club). Those noises damage the ear and lead to deafness. The “silent tire deflator” solves this danger. It reduces the noise from 115dg to 85db!
