Abstract: A vacuum insulated cryogenic fluid transfer hose provides a fluid conduit and high-pressure fitting with a highly-insulative vacuum jacket which enables convenient access to the fitting. An interface collar is mounted to an end of the transfer hose with the fluid conduit and the fitting extending therethrough, a bellows fastened at a first end to an interior of the interface collar and fastened at a second end to a pass-through collar, a slide cuff mounted to the pass-through collar and extending over the bellows and the interface collar, and a connecting nut mounted to the pass-through collar. The slide cuff is displaceable relative to the interface collar between a retracted position, wherein the connecting nut, the pass-through collar, and the bellows are retracted to expose and provide access to the fitting, and an extended position, wherein the fitting is entirely covered by the enclosure.

Abstract: An enclosure for providing a fluid conduit and high-pressure fitting of a fluid transfer hose with a highly-insulative vacuum jacket and for providing convenient access to the fitting. The enclosure includes an interface collar mounted to an end of the transfer hose with the fluid conduit and the fitting extending therethrough, a bellows fastened at a first end to an interior of the interface collar and fastened at a second end to a pass-through collar, a tubular slide cuff mounted to the pass-through collar and extending over the bellows and the interface collar, and a connecting nut mounted to the pass-through collar. The slide cuff is axially displacable relative to the interface collar between a retracted position, wherein the connecting nut, the pass-through collar, and the bellows are refracted to expose and provide access to the fitting, and an extended position, wherein the fitting is entirely covered by the enclosure.
