Abstract
Apparatus for connecting a first pre-charged section of an air conditioning system to refrigerant lines connecting the section to a second section of the system. A service unit is employed to connect each refrigerant line to the pre-charge section which includes a body fabricated from a square or rectangular piece of bar stock. A main channel is formed through the bar stock and one end of the main channels is coupled to a suitable system component in the pre-charged section by a tube. A connector having a penetratable seal is mounted in the opposite end of the channel. The connector has a male fitting that is threaded into a female fitting. One fitting is mounted in the opposite end of the main channel and the other fitting is mounted in the refrigerant line. The seal is ruptured or broken when the male fitting is threaded into the female fitting a sufficient depth to establish a leak proof joint therebetween. A process valve is also mounted on the bar stock body and communicates with the main channel via an auxiliary channel. The process valve is used in the factory to charge refrigerant into the section prior to the section being shipped into the field.
