Abstract: A lightweight hose assembly of the type adapted for carrying fuels and other corrosive fluids. The assembly (10) includes a tubular member (11) and a pair of coupling members (20). The tubular member (11) includes an inner liner (12) of a fluorocarbon polymer. A glass fiber is braided about the exterior of the inner liner (12) to form a braided layer (13). The assembly (10) further includes an outer fluorocarbon coating (14) dispersed throughout the braided layer (13) for preventing kinking or permanent deformation of the inner liner (12). A conductive strip (16) is formed on the inner liner (12) for dissipating electrical charges accumulated in the inner liner (12). A method of making the assembly (10) comprises the steps of extruding the inner liner (12). A nonmetallic material (13) is then braided about the exterior of the liner (12). The inner liner (12) and braided layer (13) are then passed through a reservoir containing a solution of the fluorocarbon polymer.
