Vapor Escape Guard [1]

A small, flexible, cone-shaped boot that is installed at the base of certain vacuum assist Stage II recovery nozzle [2] spouts to enhance the effectiveness of vapor collection.

Although similar in function to a nozzle bellows [3], a vapor escape is much smaller and does not provide an airtight seal with the motor-vehicle fill pipe. This device is also called a vapor splash guard  or an efficiency compliance device (ECD).
