ABSTRACT:
A flexible electrically heated hose of substantially uniform construction throughout its length for transmitting hot liquid material includes a flexible polymeric tube encased within a braided metal covering and having hydraulic fitting at its opposite ends. Multiple plies of heat and electrical insulative material are helically wrapped around the braided covering and a least one electrical heating line is helically wrapped and embedded within the multiple plies. A molded plastic cuff is secured to each end of the hose and an exterior ply of corrugated polymeric tubing is provided about the exterior of the hose to prevent kinking and breaking of the hose at each hose cuff caused by severe bending forces at that location. The exterior of the corrugated tubing has annular ribs separated by annular recesses into which annular ribs on the interior of each cuff extend to secure the cuffs to the corrugated tubing.
