Swivel [1]

A liquid tight device installed between the nozzle [2] and dispenser [3] hose to enhance handling ease for the user.

The swivel permits the nozzle to be rotated without rotating the hose at the same time. This means that when a motorist fuels a tank, he or she can twist the position of the nozzle without putting stress on the hose. In the absence of a swivel, a dispenser hose tends to become twisted and difficult to handle.
