Refrigerant transporting hose having inner tube including resin layer, and connector for the same

A hose-connector combination consisting of

• a refrigerant transporting hose having an end portion and a laminar structure including an inner tube consisting of at least one layer, an outer tube disposed radially outwardly of and coaxially with the inner tube, and a reinforcing fiber layer interposed between the inner and outer tubes, said inner tube including a resin layer formed of a resin composition which consists essentially of a blend of modified polyolefin and polyamide resin, and 1-10% by weight of .epsilon.-caprolactam, the proportion by weight of said modified polyolefin to said polyamide resin being within a range between 40/60 and 10/90 and
• a connector having a nipple on which the end portion of the hose is fitted, wherein the improvement comprises:
• a sealing layer interposed between an outer circumferential surface of said nipple and an inner surface of said inner tube of said hose, said sealing layer formed of a chlorinated elastomer containing a dispersion of an acid receptive agent.
