摘要： The present application relates to an apparatus of joined valves used to test and maintain refrigeration systems. More particularly, the present application provides a Multiple Valve Refrigerant Leak Protection Device having a specifically preferred embodiment including a ball valve with a soldered pipe connection, as part of the fitting with a Schrader valve, primarily used for the maintenance and transfer of refrigerant from commercial refrigeration equipment. Schrader valves are most commonly used in this application with a ball valve. A ball valve would be the preferred valve, but a wide range of valves could be used. The resulting valves can be used to test and maintain refrigeration systems, and act to prevent leakage where refrigeration fluids are often released to the atmosphere when the system is being maintained or repaired.
