ABSTRACT:
A helically wound two-piece construction hose is provided, having greater flexibility and resistance to kinking than previous helically wound two-piece construction hoses because of the provision of a hinge in a strip thereof. The hinge is made of a material which is flexible, yet has hardness, strength, and abrasion resistance, and is also resistant to fatigue failure.
