1. A hose fitting assembly for a collapse-resistant hose with at least one inner layer and an outer sheath layer, the hose fitting assembly comprising:
a sleeve having a forward sleeve end portion and a rearward sleeve end portion, the rearward sleeve end portion having an opening adapted to receive an end portion of the collapse-resistant hose;
a fitting having a rearward fitting end portion that is operatively coupled to the forward sleeve end portion;
the rearward fitting end portion having an internal surface that forms an internal cavity configured to receive an end portion of the at least one inner layer of the collapse-resistant hose;
a nipple operatively coupled to the fitting and extending in a rearward direction through the internal cavity of the fitting, the nipple being configured to fit within an internal passage of the collapse-resistant hose; and
at least one seal operatively mounted in the internal cavity of the fitting and configured to seal against an outer surface of the at least one inner layer of the collapse-resistant hose;
wherein the rearward fitting end portion is flared radially outwardly to receive the end portion of the collapse-resistant hose and is configured to be crimped radially inwardly into a sealed state in which the at least one seal engages with the outer surface of the at least one inner layer of the collapse-resistant hose.
