ABSTRACT:
A kink-resistant, small bend radius hose has a thin layer polyfluorocarbon liner tube with a thickness in the range of from about 0.005 inches to about 0.025 inches. The exterior of the liner tube is etched to allow silicone to be bonded thereto. A thin layer of silicone is bonded to the etched exterior of the liner tube. This layer of silicone serves as a bonding layer for a reinforcing layer of synthetic fabric, a helix strand and a cover layer. The reinforcing layer serves to strengthen the thin liner tube, the helix strand serves to support the hose against kinking and the cover layer adds additional strength and contains the helix strand with respect to the reinforcing fabric. Thus, a composite, integral, kink-resistant, small bend radius hose is achieved.
