摘要： A molded hose branch of rubber includes an assembly formed by slipping completely vulcanized rubber hose lengths with ends onto free ends of a plastic tubing branching piece. The assembly is placed into a mold, and a thermoplastic material, for instance a blended mixture of polypropylene and EPDM, is injection molded around the assembly so as to join the thermoplastic material to the rubber hose lengths. This results in a sleeve around the rubber hose lengths and free parts of the tubing branching piece between the ends of the rubber hose lengths.

摘要： A method for producing molded hose branches of rubber and a molded hose branch produced according to the method, includes slipping completely vulcanized rubber hose lengths with ends onto free ends of a plastic tubing branching piece for forming an assembly, placing the assembly into a mold, and injection molding a thermoplastic rubber material in the form of a blended mixture of polypropylene and EPDM around the assembly for joining the thermoplastic material to the rubber hose lengths for forming a sleeve around the rubber hose lengths and free parts of the tubing branching piece between the ends of the rubber hose lengths.
