The Trane GLS0077 Sight Glass is an inspection part that is used to ensure the refrigerant status in closed piping systems is visually verified. A transparent viewing window fitted the liquid line enables one to view the refrigerant movement and condition as it flows through the refrigerant pathway utilized in HVAC systems. The sight glass body is attached in line with the refrigerant line forming an observation point that is closed in the circuit. It is located along the liquid line and close to the filtration or metering parts to monitor the refrigerant when the system is running.
