Claim 12:
13. A method of forming an evacuation hose system comprising:
attaching a first connector to an evacuation hose;
forming a second connector on a first system attachment portion, wherein the second connector is configured to be removably coupled to the first connector of the evacuation hose, and is further configured for mechanical attachment to a first attachment point for a first refrigeration system; and
forming a third connector on a second system attachment portion, wherein the third connector is configured to be removably coupled to the first connector of the evacuation hose, and is further configured for mechanical attachment to a second attachment point for a second refrigeration system, and further wherein the first attachment portion is unable to be mechanically coupled to the second refrigeration system and the second attachment portion is unable to be mechanically coupled to the first refrigeration system,
wherein at least one of the first connector, the second connector, and the third connector comprises a face defining an outlet of a fluid passageway, wherein the face and the outlet of the fluid passageway are substantially concentric and substantially coplanar,
wherein the face includes an indentation,
wherein the first connector and the second connector are configured to form a sealing engagement to permit refrigerant flow between the evacuation hose and the first refrigeration system, and
wherein the first connector and the third connector are configured to form a second sealing engagement to permit refrigerant flow between the evacuation hose and the second refrigeration system to permit the evacuation hose to be used to evacuate refrigeration system contents from either the first refrigeration system or the second refrigeration system.
