The ANWSG sight glass is used on the liquid pipelines of refrigeration and air conditioning devices to indicate the flow status of the refrigerant, the water content in the refrigerant, and the flow status of lubricating oil in the return oil pipeline of the oil separator. The sight glass is equipped with a moisture indicator that indicates the moisture content in the refrigerant by changing its color. The sight glass is used to measure the level of refrigerant in the reservoir or the level of lubricating oil in the compressor crankcase. The sight glass is sealed with modified PTFE material, suitable for various refrigerants and refrigeration oils. Adopting an explosion-proof crimping structure, the observation window is clear and safe.
