ABSTRACT:
The present invention is directed to a new and improved flexible hose assembly for transmitting pressurized air, gases and/or fluids between two spaced apart components. The hose assembly includes an inner liner surrounded by a helix formed of thermoplastic material having a substantially flat surface portion for bonding with the inner liner, eliminating the need for a outer cord to prevent the helix from floating relative to the liner. A self-adjusting retainer ring serves to compress the flexible hose onto the beaded end portion of a component with increasing pressure as the pressure increases within the hose assembly. Preferably the retainer ring is formed from a single piece of thermoplastic material.
