Both Model SGN sight glass and Model SGS sight glass are used on the liquid piping of the refrigeration and air conditioning unit to indicate the flow condition of the refrigerant, water cut of the refrigerant and lubricant oil return piping on the oil separtor.

Model SGN sight glass and Model SGS sight glass are equipped with onemoisture indictor, which will change color to indicate the water cut in the refrigerant.

Model SGR sight glass is used to indicate the level of the refrigerant in the liquid drum and lubricant oil level in the compressor crankcase.

The modified PTFE sealing is used in both Model SGN sight glass and Moedl SGR sight glass, which is applicable to various refrigerants and oils with perfect sealing performance.

The structure of both Model SGN sight glass and Model SGR sight glass is an explosion-proof press fit and the view glass is clear and safety.

Model SGS sight glass is an independent body structure with conventional sintered glass and O-ring seal.
