Compressor Fitting HVAC: Description and Operation
The A/C manifold and tube is attached to the A/C compressor, is sealed with O-ring seals, and has the following features:
-
The upstream side contains low pressure refrigerant gas.
-
The downstream side contains high pressure refrigerant gas and a fitting used to mount a serviceable high-pressure A/C charge port valve.
-
The downstream side also contains a fitting used to mount the A/C pressure cutoff switch. A long-travel Schrader-type valve stem core is installed
in the fitting so that the A/C pressure cutoff switch can be removed without discharging the A/C system.
