Abstract
A cover for a fill port of a flow controller of a high pressure fitting for filling a cylinder with a pressurized gas. The cover has a slidable cover plate having elongated flexible members attached thereto, such member having a locking projection that cooperatively fits into a locking recess on the cover plate. The cover plate is movable from a first position covering the fill port to a second position away therefrom. Elastomeric means bias the cover plate towards the first position. A fill port adaptor is used to fill the cylinder through the fill port, and may have a cover that prevents operation when the cover is in place. Both covers are adapted to open when the flow controller is properly placed in a cradle that forms part of the fill port adaptor.
