R12 Auto Air Conditioning AC Refrigeration Charging Gauges Set

Our A/C Manifold Gauge Set is designed to test automotive air conditioning systems (using R12 only) by comparing the "high side" and "low side" pressure reading to the vehicle manufacturer’s A/C system specifications. The high-pressure gauge measures compressor discharge pressure, and the low-pressure gauge measures suction. Set includes quick-disconnect valves, sight glass, high-pressure safety valve, color-coded gauges, valves and hoses.

Gauge accuracy is +/- 2% Measurements are rough estimates.
