Cooling Sight Glasses

Use a refrigerant sight glass to test for areas of moisture in refrigeration and air-conditioning systems. The sight glass has a gauge that displays levels reading dry, caution, or wet, to indicate if the system has moisture. A positive moisture indicator could mean the harmful acids are prevalent, which is damaging to a system. Our refrigeration gauges have plated steel construction with copper fittings and different sizes to best work with your unit, as they mount onto a receiver or compressor crankcase. We also carry many other AC and refrigeration accessories, such as refrigeration access valves and thermostatic expansion valves to control refrigerant releases. Our manifold gauge set accessories has hose sets, adapters and more.
