Abstract:
A method for producing a metal hose coupling which is adapted to be mounted permanently on the end of a hose for pressurized hydraulic oil, which hose coupling then creates a fluid connection between the hose and an attachment member, the hose coupling having at least one hose nipple which, in the fitted state, projects into the hose and a connecting part, which is adapted to form a connection to the attachment member, the hose coupling furthermore comprising, for each hose nipple, a deformable sleeve which, in the fitted state, rests around that part of the hose which has been pushed onto the hose nipple and, with deformation to the sleeve, holds the hose on the hose nipple, an oil passage extending through the connecting part and the at least one hose nipple, wherein said method comprises the step of producing the connecting part and the hose nipple as a single-piece body by means of a metal injection moulding process.
