Abstract:

A flexible hose having an end connection fitting capable of withstanding high pressures and high end loads comprises a nipple having a stop ring on its outer periphery and a plurality of protruberances between the stop ring and the rear end of the nipple. A substantially tubular inner hose portion overlies the nipple, abuts the stop ring and extends away from the rear end of the nipple. A plurality of lays of spirally wound reinforcing wires overlie the inner portion of rubber and abut the stop ring. A sleeve overlies the nipple and is spaced therefrom. The inner periphery of the nipple has a roughened surface. A substantially tubular outer portion of an elastomer abuts the rear of the sleeve and overlies the reinforcing wires outside of the sleeve. A synthetic resin permeates the space between the wires and fills the space between the inner periphery of the sleeve and the inner portion of elastomer.
