Abstract
A unitary hose connection for servicing an automobile air conditioning system is provided. A first connector is disposed at one first end and is connectable with a low pressure service port of an automobile air conditioning system. A second connector is disposed at the other end of the hose and is selectively connectable with both a pressure gauge and a can tap valve. The can tap valve is attachable to a can of compressed refrigerant. When a pressure gauge is attached to the second connector and the first connector is attached to the service port, the pressure of the refrigerant in the automobile air conditioning system can be measured. When the second connector is attached to the can tap valve, the compressed refrigerant in the can may be introduced into the automobile air conditioning system to thereby service the system. The hose connection, pressure gauge, can tap valve, and can of refrigerant may be packaged together in a kit.
