Abstract
The coupling has a stem and a ferrule. The stem is placed against an uncured hand-built steel cable reinforced hose. The steel reinforcement cable is spiraled onto a smaller diameter portion of the stem. The ferrule is then slid over the stem and over the reinforcing cable layers. Epoxy resin is injected through ports in the ferrule to embed the reinforcing cables and securely fix the hose structure to the stem and ferrule of the coupling. A cover is applied over the ferrule. The hose-coupling assembly is subjected to heat and pressure to cure the elastomeric portions of the hose and securely bond them to the surfaces of the coupling. The hose-coupling assembly is useful in very heavy duty applications where the assembly must withstand large end load strains when the hose is not under internal pressure, such as hose for use on a jetting sled.
