product description

●SGN type sight glass is used in the liquid pipeline of refrigeration and air-conditioning devices to indicate the flow condition of refrigerant, the water content in refrigerant and the flow condition of lubricating oil in the oil separator return line.

●SGN type sight glass has a humidity indicator, which indicates the water content in the refrigerant by changing the color.

●SGN type sight glass uses modified PTFE sealing material, suitable for a variety of refrigerants and freezing oil

It also has good sealing performance.

●SGN type sight glass adopts explosion-proof crimping structure, and the observation window is clear and safe.

technical parameter:

Applicable refrigerant: HCFC and HFC

Applicable medium temperature: -40°C~+80°C

Maximum working pressure: 4.5MPa

Maximum pressure resistance: 6.8MPa

Annual refrigerant leakage: ≤2g R22/a

Note: 

The allowable water content of fully enclosed compressors is generally between 30-75ppm, while other compressors are slightly higher. In order to effectively protect the system, the indicator must be carefully monitored. If the color changes to yellow, the dryer must be replaced.

SGN features:

●Used for HCFC/HFC refrigerant

●Indicates excessively high water content in the system

●No indication of supercooling of refrigerant liquid

●Insufficient refrigerant charge indication

●Using modified PTEE sealing material, suitable for a variety of refrigerants and freezing oils, and has good sealing performance.

●Adopt explosion-proof pressure structure, the observation window is clear and safe.

●Using high-quality copper rod forging, high strength and good plasticity.
