Why Use a Sight Glass?
A sight glass is an essential diagnostic tool in any refrigeration or HVAC system. It allows technicians to visually confirm proper refrigerant charge, detect moisture contamination (indicated by a color-changing moisture indicator), and verify that liquid refrigerant — rather than flash gas — is reaching the expansion device. Regular inspection through the sight glass helps prevent costly compressor damage and system inefficiency.
