Tool J-38702 is a straight adapter which allows existing diagnostic equipment to be connected to the service port, and high side pressures to be checked
by opening the port. The adapter connects, first to the gage hose and then to the high side pressure port, by threading the adapter to the port.
IMPORTANT:
Tool J-38702 Adapter MUST BE ASSEMBLED to the fitting FINGER TIGHT. Using a tool to tighten this adapter may exceed the
assembly torque of the 2 piece High Side Service Port Assembly. If this occurs, the attempted removal of the adapter may result in the
service port fitting being removed with it, causing loss of refrigerant.
Tool J-38704 is an octagon socket which is used to unthread the A/C high side pressure port from the high side A/C line and then used to thread the new
port back onto the high side pressure line.
