ABSTRACT:
A high pressure hose fitting, and method for sealing the hose to a fitting, is disclosed for use with hoses of the type including a linear disposed about an axially extending passageway, and a reinforcement layer circumventing the liner. The liner is preferably pulled slightly beyond the edge of the reinforcement layer to form a protruding edge region. An end fitting, having a flange with a liner-receiving groove, is inserted into the passageway until the protruding edge of the liner contacts the end wall of the groove, and the flange abuts the reinforcement layer. A swagable collar circumventing the foregoing components is swaged radially inwardly to clamp the liner on its outside diameter.
