Abstract
An improved vapor receiving system for a gasoline dispensing nozzle having a stronger magnetic sealing section and a more flexible and durable bellows construction. The magnetic sealing section has a magnetic ring backed by a second ring attracted to the magnet which acts as a pole piece to increase the magnetic attractions toward the fillpipe during the filling and vapor receiving process. The magnetic sealing section cover and bellows section are made from a thin, flexible reinforcement mesh impregnated with natural or synthetic elastomer such as vinyl.
