1. A method of forming a hydraulic connection between a hydraulic component and a thermoplastic hydraulic hose, the method comprising:
forming a hydraulic hose assembly by a process comprising:
threading a metal ferrule onto an end section of the thermoplastic hydraulic hose, the end section of the thermoplastic hydraulic hose having an open end;
crimping an inner circumferential surface of the metal ferrule to an outer circumferential surface of the end section of the thermoplastic hydraulic hose to fixedly adjoin the metal ferrule to the thermoplastic hydraulic hose; and
threading an annular gasket onto the end section of the thermoplastic hydraulic hose between the metal ferrule and the open end of the thermoplastic hydraulic hose, the annular gasket concentric with, and adjacent to, the metal ferrule;
inserting a length of the hydraulic hose assembly into an axial bore of a body of the hydraulic component such that the metal ferrule and the annular gasket are disposed within the axial bore; and
securing the hydraulic hose assembly to the body of the hydraulic component.
