Abstract (en)
[origin: WO2019145749A1] The subject of the invention is a coolant line of a refrigerant circuit consist of at least one rigid pipe (1) connected to an end of a flexible hose (2). This hose comprise an inner corrugated tube (3) with outer surface coated with an elastomer (5), a cylindrical fitting (6) at each end of the corrugated tube (3). Moreover the flexible hose (2) has an outer composite hose (13) covering the corrugated tube (3) and a major part of each fitting (6), a socket (17) clamped around each fitting (6) and end of the outer composite hose (3). The fittings (6) are inseparably connected to the corrugated tube (3) by a weld (12). The invention relates also to a method of manufacturing thereof.
