Claims

A hose assembly,
a hose defining an inner fluid passageway and an outer surface;
a connection port provided at the first end of the hose;
a heat insulating material covering the outer surface of the hose;
a cover surrounding the heat insulating material;
an elastic sleeve extending over at least a portion of the connection opening and the cover to compressively engage the connection opening and at least a portion of the cover , wherein the elastic sleeve extends over the connection opening and at least a portion of the cover; an elastic sleeve provided in a material configured to allow attachment by elastic stretching of said elastic sleeve ;
A hose assembly comprising
A hose assembly, wherein said insulation, said cover , and said elastic sleeve are each rated for continuous use at a temperature of at least about 135°C.

2. The hose assembly of claim 1, wherein said insulating material comprises PTFE-based aerogel .

The hose assembly of claim 1 , wherein the insulation is rated for continuous use at temperatures between about -53°C and about 250°C.

2. The hose assembly of claim 1 , wherein the insulation is rated for continuous use at temperatures of at least about 250<0>C.

2. The hose assembly of claim 1 , wherein said insulating material has a maximum thermal conductivity of less than about 25 mW/mK at about 23[deg.]C.

2. The hose assembly of claim 1 , wherein the insulation is capable of meeting a flammability rating of UL94 V-0.

2. The hose assembly of claim 1 , wherein the insulation comprises a first strip of insulation that spirals around the outer surface of the hose.

8. The hose assembly of claim 7, wherein the first strip of insulation spirally wraps around the outer surface of the hose with an overlap of approximately 50%.

8. The hose assembly of claim 7 , wherein the insulation comprises a second strip of insulation spirally surrounding the first strip of insulation.

8. The hose assembly of claim 7 , wherein the first strip of insulation has a maximum elongation along its entire length of about 1% at 5 lbs tension and a minimum elongation across its width of about 10% at 5 lbs tension.

2. The hose assembly of claim 1 , wherein said cover comprises a fabric cover covering said insulation.

12. The hose assembly of claim 11, wherein the fabric cover comprises PTFE/polyester engineered fabric.

12. The hose assembly of claim 11 , wherein the textile cover comprises a textile strip that spirally wraps around the insulation.

14. The hose assembly of claim 13, wherein the fiber strip spirally wraps around the insulation with an overlap of approximately 50%.

14. The hose assembly of claim 13 , wherein the fiber strip spirally wraps around the insulation without adhesive.

14. The hose assembly of claim 13 , wherein the fiber strip spirally wraps to maintain a tension of at least about 5 lbs.

2. The hose assembly of claim 1 , wherein the cover comprises heat shrink polymer tubing.

18. The hose assembly of claim 17, wherein said polymer tube comprises polyolefin .
