What device must the transfer hose on an automatic dispenser incorporate?

The transfer hose on an automatic dispenser must incorporate a pull-away device to enhance safety during the refueling process. This device is designed to prevent damage and potential spills by allowing the hose to disconnect cleanly if it is inadvertently pulled or tugged while the vehicle is being fueled. This feature is crucial in maintaining safety standards, as it helps avoid hazardous situations that could arise from a disconnected or damaged hose.

In addition to preventing spills and accidents, the pull-away device helps ensure that the refueling process can occur without interruption and with minimal risk to both the operator and the equipment. Incorporating this device is a best practice in the design of CNG dispensers to align with safety regulations and standards set by industry bodies.
