Description
The Trane GLS00931 Sight Glass / Liquid Indicator is a refrigerant monitoring component used to observe liquid flow conditions within sealed refrigeration circuits. Configured with a 1.125-24 connection specification, this indicator is commonly positioned along the liquid line in chillers, condensing units, and other HVAC systems where refrigerant condition monitoring is required. It allows technicians to visually inspect refrigerant movement and identify the presence of bubbles or moisture-related conditions during operation. The sight glass supports system evaluation procedures by providing a visible indication of liquid refrigerant flow within the circuit.
