Why Use a Moisture/Liquid Indicator?
Moisture in a refrigeration system can cause acid formation, freeze-ups at the expansion valve, and compressor damage. A liquid line sight glass with moisture indicator allows technicians to:
- Confirm a full, bubble-free liquid line — ensuring proper system charge
- Detect moisture before it causes costly system damage
- Diagnose refrigerant undercharge or restrictions quickly during service calls
Typical Applications
- Residential and commercial air conditioning systems
- Refrigeration equipment liquid lines
- Heat pump systems
- Any 1/2″ ODF copper liquid line requiring moisture and flow monitoring
