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.

1. A vacuum enclosure for coupling a cryogenic fluid handling hose to a cryogenic fluid holding structure, comprising: an interface collar adapted to be mounted to an end of the cryogenic fluid handling hose;a bellows coupled at a first end to the interface collar and coupled at a second end to a pass-through collar;a slide cuff coupled to the pass-through collar and extending over at least a portion of the bellows and the interface collar, wherein the slide cuff is axially displaceable relative to the interface collar to facilitate movement of the slide cuff between a retracted position and an extended position; anda connecting nut coupled to the pass-through collar and longitudinally separated from the slide cuff by a thrust bushing disposed longitudinally intermediate the connecting nut and the slide cuff, the connecting nut configured to releasably engage a portion of the cryogenic fluid holding structure;wherein in the extended position the pass-through collar and the bellows form a sealed conduit between the cryogenic fluid handling hose and the cryogenic fluid holding structure. 2. The enclosure in accordance with claim 1, wherein in the retracted position the connecting nut is released from engagement with the cryogenic fluid holding structure to expose a high pressure fitting that is configured to couple first and second conduits associated with the cryogenic fluid handling hose and the cryogenic fluid holding structure, respectively. 3. The enclosure in accordance with claim 2, further comprising a vacuum extension disposed about a portion of the first conduit, the vacuum extension coupled at a first end to an outer surface of the first conduit, the vacuum extension coupled at a second end to the cryogenic fluid handling hose, the vacuum extension and the outer surface of the first conduit forming an annular space open at the second end to enable removal of air from the annular space. 4. The enclosure in accordance with claim 1, wherein the connecting nut is rotatably mounted to the pass-through collar. 5. The enclosure in accordance with claim 1, further comprising a retaining collar mounted to an exterior of the pass-through collar for minimizing axial displacement of the connecting nut and the slide cuff relative to the pass-through collar. 6. The enclosure in accordance with claim 1, wherein the slide cuff fits over the interface collar in a radially close-clearance relationship therewith for minimizing radial displacement therebetween. 7. The enclosure in accordance with claim 1, further comprising a vacuum port associated with the enclosure for providing a passageway therethrough to facilitate removal of air from an interior portion of the enclosure. 8. A vacuum enclosure for coupling a cryogenic fluid handling hose to a cryogenic fluid holding structure, comprising: a bellows adapted to be coupled at a first end to an end of the cryogenic fluid handling hose and coupled at a second end to a pass-through collar, wherein the bellows and pass through collar can be extended and retracted relative to the fluid handling hose between an extended position and a retracted position;a connecting nut coupled to the pass-through collar, the connecting nut configured to releasably engage a portion of the cryogenic fluid holding structure;a retaining collar mounted to an exterior of the pass-through collar for minimizing axial displacement of the connecting nut relative to the pass-through collar, the retaining collar longitudinally separated from a flange of the connecting nut by a thrust bushing disposed longitudinally intermediate the retaining collar and the flange; andwherein in the extended position the pass-through collar and the bellows form a sealed conduit between the cryogenic fluid handling hose and the cryogenic fluid holding structure. 9. The enclosure in accordance with claim 8, wherein in the retracted position the connecting nut is released from engagement with the cryogenic fluid holding structure to expose a high pressure fitting that is configured to couple first and second conduits associated with the cryogenic fluid handling hose and the cryogenic fluid holding structure, respectively. 10. The enclosure in accordance with claim 9, further comprising a vacuum extension disposed about a portion of the first conduit, the vacuum extension coupled at a first end to an outer surface of the first conduit, the vacuum extension coupled at a second end to the cryogenic fluid handling hose, the vacuum extension and the outer surface of the first conduit forming an annular space open at the second end to enable removal of air from the annular space. 11. The enclosure in accordance with claim 8, wherein the connecting nut is rotatably mounted to the pass-through collar. 12. The enclosure in accordance with claim 8, further comprising a vacuum port associated with the enclosure for providing a passageway therethrough to facilitate removal of air from an interior portion of the enclosure. 13. A vacuum enclosure for coupling a cryogenic fluid handling hose to a cryogenic fluid holding structure, comprising: a bellows adapted to be coupled at a first end to an end of the cryogenic fluid handling hose and coupled at a second end to a pass-through collar, wherein the bellows and pass through collar can be extended and refracted relative to the fluid handling hose between an extended position and a retracted position;a connecting nut coupled to the pass-through collar, the connecting nut configured to releasably engage a portion of the cryogenic fluid holding structure; anda vacuum port associated with the vacuum enclosure for providing a passageway therethrough to facilitate removal of air from an interior portion of the enclosure;wherein in the extended position the pass-through collar and the bellows form a sealed conduit between the cryogenic fluid handling hose and the cryogenic fluid holding structure. 14. The vacuum enclosure in accordance with claim 13, wherein in the retracted position the connecting nut is released from engagement with the cryogenic fluid holding structure to expose a high pressure fitting that is configured to couple first and second conduits associated with the cryogenic fluid handling hose and the cryogenic fluid holding structure, respectively. 15.
