Abstract
One aspect of the disclosure is a method of attaching a hose coupling to a reinforced hose. In one embodiment, the method comprises: skiving the first end of the reinforced hose to expose at least one reinforcing layer of a plurality of reinforcing layers of the reinforced hose; positioning the skived first end of the reinforced hose in an inner cavity of the hose coupling; introducing a vacuum into the inner cavity through a vent port in the hose coupling; and introducing a bonding agent into the cavity through an injection port in the hose coupling, wherein the bonding agent is drawn by the vacuum into the plurality of reinforcing layers of the reinforced hose.

A method of attaching a hose coupling to a first end of a reinforced hose, the method comprising:
- obtaining a reinforced hose, the reinforced hose having a skived first end exposing at least one of a plurality of reinforcing layers and having a remaining outer cover portion;
- obtaining a hose coupling having an inner cavity, the inner cavity having a coupling end and an opposing aft end;
- positioning the skived first end of the reinforced hose in the inner cavity, the positioning:
- abutting a leading edge of the skived first end with the coupling end of the inner cavity;
- sealing the leading edge of the skived first end with the coupling end of the inner cavity with a first seal;
- and
- sealing the outer cover portion with the opposing aft end of the inner cavity with a second seal;
- placing a first vacuum containment device around the hose coupling and remaining outer cover portion;
- sealing the first vacuum containment device to the remaining outer cover portion with a vacuum sealing mechanism;
- introducing a vacuum into the inner cavity through a vent port in the hose coupling while the first vacuum containment device is sealed to the remaining outer cover portion;
- and
- introducing a supply of bonding agent into the inner cavity through an injection port in the hose coupling while the first vacuum containment device is sealed to the remaining outer cover portion, wherein the bonding agent is drawn by the vacuum into the plurality of reinforcing layers of the reinforced hose;
- and
- stopping introducing the supply of the bonding agent into the injection port after the bonding agent is detected at the vent port.
