Carrier KM680005 5/8" ODF Refrigerant Sight Glass

The Carrier KM680005 is a 5/8" ODF (Outside Diameter Flare) refrigerant sight glass designed for monitoring refrigerant flow and system health in commercial refrigeration and HVAC applications. This critical component provides technicians with visual confirmation of refrigerant levels, flow quality, and moisture content within the refrigeration system.

Key Features:

• 5/8" ODF connection size for standard refrigeration line integration
• Clear viewing window allows visual inspection of refrigerant condition
• Helps identify low refrigerant levels indicated by air bubbles in the flow
• Moisture indicator capability on select models helps detect system contamination
• Durable brass construction withstands demanding refrigeration system pressures
• Compatible with Carrier and Bryant refrigeration systems

Sight glasses are essential diagnostic tools that enable quick identification of refrigeration system issues without requiring invasive testing. The presence of excessive bubbles in the sight glass typically indicates insufficient refrigerant charge, while clear, bubble-free flow confirms proper system operation and refrigerant levels.
