Claim 0:
1. An interchangeable evacuation hose system comprising:
an evacuation hose with a first connector coupled thereto;
a first system attachment portion with a second connector, 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 by way of the first system attachment portion; and
a second system attachment portion with a third connector, 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 by way of the second system attachment portion, 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, or 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,
the face includes an indentation,
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
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.
