Abstract
A non-interchangeable two-component connecting valve capable of connecting a fuel supply to a fuel cell or other device is disclosed. One component of the connecting valve comprises at least one center post and one internal elastomeric seal, which opens when moved or compressed by a correctly sized and dimensioned mating tube from the other component. In one embodiment, only one valve component has one or more internal seals. In alternate embodiments, both valve components have one or more internal seals, which can open simultaneously or sequentially.
