Abstract
A hose construction having a coupling secured to an end of a hose, with the coupling including a tubular insert formed with a polymer mixed with chopped reinforcement fiber and including first and second ends, with the first end being inserted in the hose, and the second end including a connector interface. A tubular metallic ferrule is connected to the tubular insert adjacent to the second end in order to form an annular hose receiving space between an outer surface of the insert and an inner surface of the ferrule. The end of the hose is received in the annular hose receiving space, and the ferrule is deformed inwardly against the hose to form a secure connection. The tubular insert formed of a non-metallic material has high strength and is resistant to corrosion due to contact with the materials being transported.
