Sight Glasses

  • Fetures of RSG

    • RSG sight glasses 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 flow condition of the oil return piping on the oil separator.
    • RSG sight glasses are equipped with one moisture indicator, which will change color to indicate the water ratio in the refrigerant.
    • RSG sight glasses are used to indicate the level of the refrigerant in the liquid drum and the lubricant oil level in the compressor crankcase.
    • The modified PTFE sealing is used in both Model RSG sight glasses, which is applicable to various refrigerants and oils with perfect sealing performance.
    • The structure of both Model RSG sight glasses are an explosionproof press fit and the viewing glass is clear and safety.
    • RSG sight glasses are an independent body structure with conventional sintered glass and O-ring seal.
    • Design for HCFC/HFC refrigerants.
