Abstract
A flexible hose assembly includes a length of tubular hose formed from a spiral-wrapped layer of polymer material. A helical stiffener is disposed on an outer surface of the tubular hose. The helical stiffener comprises an elastomer material that is configured to bond or adhere to the polymer material of the tubular hose.

A flexible hose assembly, comprising:
- a length of tubular hose formed from a spiral-wrapped layer of polymer material;
- and
- a helical stiffener disposed on an outer surface of the tubular hose,
- wherein the helical stiffener comprises an elastomer material that is configured to bond to the polymer material of the tubular hose, and
- wherein an end of the tubular hose includes one or more pull tabs that aid in installation of the tubular hose onto an end of a duct or flange.

A method of manufacturing a flexible hose assembly, the method comprising:
- arranging a mandrel;
- wrapping the mandrel with a polymer tape to form a spiral wrapped tubular hose;
- applying an elastomeric helical stiffener along an outer surface of a length of the spiral wrapped tubular hose;
- bonding the helical stiffener to the spiral wrapped tubular hose;
- and
- trimming an end of the spiral wrapped tubular hose, and forming a plurality of tabs at the end of the spiral wrapped tubular hose.
3 more elements
A flexible hose assembly, comprising:
- a length of tubular hose formed from a spiral-wrapped layer of polymer material;
- a helical stiffener disposed on an outer surface of the tubular hose;
- and
- an end cuff at one end of the tubular hose, the end cuff including a first bead of elastomeric material oriented in a substantially longitudinal direction along the outer surface of the tubular hose, the first bead overlapping a portion of the elastomeric helical stiffener,
- wherein the helical stiffener comprises an elastomer material that is configured to bond or adhere to the polymer material of the tubular hose.
