Crimp hydraulic hose fittings with metric connection join hydraulic hoses to equipment or hoses that have metric threads. They have a crimped end that attaches to hydraulic hoses and a metric threaded end that attaches to equipment or other hoses. A crimping device seals the fitting for a permanent connection. These fittings are typically used to repair or create new hose assemblies for hydraulic systems in oil and gas, industrial, mining, and machine-tool applications.
