Claim:
1. A hose assembly, comprising: a tube comprising a polymeric material, the tube having a first end and a second end, an end fitting comprising a coupler comprising a threaded section mateably engageable with a coupler of another device, a flexible polymeric sleeve having a first end and a second end, wherein the sleeve extends over a portion of the tube with the first end of the sleeve located adjacent the first end of the tube, wherein the first end of the sleeve and the first end of the hose are fixedly secured to the end fitting, wherein the sleeve has a first wall thickness in a connection segment extending a distance from the first end of the sleeve and a lesser, variable wall thickness along a length of the sleeve inwardly from the connection segment in a strain reducing segment that tapers down in wall thickness in a direction towards the second end, wherein the sleeve has a minimum wall thickness at the second end of the sleeve in the strain reducing segment that extends from adjacent a ferrule of the end fitting to the second end of the sleeve that is greater than 50% of a minimum wall thickness of the sleeve in the connection segment, wherein the ferrule is a component separate and distinct from the coupler.
