ABSTRACT:
Swage end-connector for high pressure reinforced flexible hose particularly suitable in the petrochemical and drilling industries for hoses. Two connectors are disclosed one for intermediate hose pressure burst ratings up to 12,500 psi and internal diameters up to 3½ inches and higher hose pressure burst ratings up to 18,750 psi and internal diameters up to 4 inches. Both embodiment connectors will withstand the rated burst pressure of the hose to which they are connected and will withstand a pump-off force that exceeds the burst pressure of the hose. That is, the hose will fail before the connector pops off the hose.
