Abstract
Abstract 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 hose 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.
