Refrigerant Lines

The condenser to evaporator tube contains high pressure liquid refrigerant upstream of the A/C evaporator core orifice.

The A/C compressor to condenser discharge line contains high pressure refrigerant gas. It has the following features:

• An integral non-serviceable muffler.
• 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.)
• A fitting used to mount a serviceable high-pressure A/C charge port valve.

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 port to mount the A/C compressor pressure relief valve.

  The accumulator to compressor tube has a fitting used to mount the A/C cycling switch. A long-travel Schrader-type valve stem core is installed in the fitting so that the A/C cycling switch can be removed without discharging the A/C system.
