A flexible hose construction and method of making the same are provided, the flexible hose construction comprising an inner tube made of polymeric material, an outer sleeve of reinforcing material disposed in telescoping relation on the inner tube from one end thereof to the other end thereof, rib structure disposed between the sleeve of reinforcing material and the inner tube, the rib structure being disposed on the inner tube so as to define alternating coil structure of rib structure and coil structure of non-rib structure serially along the longitudinal axis of the inner tube in a like repeating pattern thereof, the coil structure of non-rib structure comprise coil structure of void space, and an outer tube of polymeric material disposed between the rib structure and the sleeve of reinforcing material so as to extend in a generally straight-line manner from coil structure of the rib structure to coil structure of the rib structure so as to tend to prevent the sleeve of reinforcing material from entering into the coil structure of void space an amount that would tend to substantially reduce the flexibility characteristics of the hose construction.

Flexible hose construction and method of making the same

A flexible hose construction and method of making the same are provided, the flexible hose construction comprising an inner corrugated hose made of polymeric material and having a plurality of outwardly convex projections with recesses therebetween and extending from one end thereof to the other end thereof, an outer sleeve of reinforcing material disposed in telescoping relation on the inner hose, and a tube of polymeric material disposed between the sleeve of reinforcing material and the inner hose and extending in a generally straight-line manner from projection to projection of the inner hose so as to tend to prevent the sleeve of reinforcing material from entering into the recesses of the inner hose an amount that would tend to substantially reduce the flexibility characteristics of the inner hose.

A hose construction, coupling therefor and methods of making the same are provided, the hose construction comprising a tubular hose and a coupling secured to one end of the tubular hose, the inner peripheral surface of the tubular hose comprising an inner corrugated lose made of polymeric material and having inwardly convex projections with recesses therebetween and extending from one end of the tubular hose to the other end thereof, the coupling having an insert disposed in the one end of the tubular hose and being radially outwardly expanded into sealing relation with the inner corrugated hose, the insert having an outer peripheral surface defined by a plurality of outwardly convex projections with recesses therebetween, the projections of the insert being respectively received in the recesses of the inner hose and the projections of the inner hose being respectively received in the recesses of the insert whereby the interior of the tubular hose is substantially sealed to the interior of the coupling.
