End connector for high pressure reinforced rubber hose

A high pressure reinforced hose assembly, comprising:

• an end connector having a coupler end and a hose receiver end, comprising:
• a ferrule attached to a stem at an attachment point adjacent the coupler end, the stem and ferrule having a cavity located therebetween, extending along a length of the end connector, configured to receive an end of a reinforced hose therein, and divided into:
• at least two gripping zones extending from adjacent a point where the ferrule is attached to the stem toward the hose receiver end, the at least two gripping zones including:
• a first gripping zone located adjacent the point where the ferrule is attached to the stem and having a first plurality of flutes and lands formed in the stem, and a second plurality of flutes and lands formed in the ferrule, wherein a distance between each of the flutes of the first plurality in the stem is different from a distance between each of the flutes of the second plurality, as taken along a longitudinal central axis of the end connector, and wherein the first gripping zone includes an expansion zone located adjacent the attachment point;
• and
• a second gripping zone located nearer the hose receiver end than the first gripping zone and having a third plurality of flutes and lands formed in the stem, wherein a distance between each of the flutes of the third plurality is different from the distance between each of the flutes of the first and second plurality, as taken along the central axis, and having a fourth plurality of flutes and lands formed in the ferrule, wherein a distance between each of the flutes of the fourth plurality is different from the distance between each of the flutes of the second plurality, as taken along the central axis;
• and
• a section of high pressure reinforced hose having first and second ends, an innermost liner, and one or more reinforcement layers located over the innermost liner, the first end being received within the cavity such that a portion of the one or more reinforcement layers engages a reinforcement liner stop formed in the stem and located nearer the expansion zone than the first plurality of flutes and landings lands, the hose extending into the expansion zone, and the innermost liner engaging an inner liner stop formed in the stem located nearer the hose receiver end than the reinforcement liner stop.
