The new line of automatic quick couplers provides a reliable and quick connection to and disconnection from the cooling system in pressure and in vacuum, too.
An integral safety sleeve holds the coupler absolutely securely to the male service connection.
The color-coded knob (red or blue) makes the high pressure and low pressure identification easier.

Once the AV 134 has been fastened, the operator can decide whether the connection with A/C system will be open or closed, by means of the hand-wheel.
AV 134 are available in a wide range of connections that can fit any commonly used equipment.
