Abstract
A method of making a lightweight hose assembly including a step of extruding the inner liner. A nonmetallic material is then braided about the exterior of the liner. The inner liner and braided layer are then passed through a reservoir containing a solution of the fluorocarbon polymer. The solvent is then removed, leaving a fluorocarbon polymer coating dispersed throughout the braided layer.

A method for constructing a hose assembly comprising the steps of:
- providing an inner tubular liner (12) of a fluorocarbon polymeric material;
- applying a braided reinforcing material (13) having gaps extending therethrough about the inner tubular liner (12);
- dispersing a second fluorocarbon polymeric material (14) and a carrier fluid into the reinforcing material (13), whereby the second outer fluorocarbon coating covers the braided material but does not extend radially outwardly from the periphery of the braided material, and sintering the assembly.
A method for constructing a hose assembly comprising the steps of:
- extruding an inner tubular liner (12) of a fluorocarbon polymeric material;
- braiding a nonmetallic material (13) about the exterior of the inner liner (12);
- passing the inner tubular liner (12) having the braided material (13) thereon through a reservoir containing an aqueous dispersion of a second fluorocarbon polymeric material, drying the water from the aqueous solution to leave an outer fluorocarbon material (14) dispersed through the braided material (13), whereby the outer fluorocarbon coating covers the braided material but does not extend radially outwardly from the periphery of the braided material, and sintering the assembly.
