Why Use a Sight Glass?

Sight glasses are a critical diagnostic tool in any refrigeration or HVAC system. By providing a direct visual window into the liquid line, technicians can immediately detect flash gas (indicating low refrigerant charge), moisture contamination, or oil slugging — all without interrupting system operation. Regular visual checks through the sight glass can prevent costly compressor damage and extend overall system life.
