Supco SG206 Sight Glass

Supco SG206 Sight Glass

The Supco SG206 Sight Glass is a professional-grade refrigeration moisture indicator designed for precise visual monitoring of liquid line conditions. Featuring 1/2" x 1/2" flare (FLR) connections (1/2" Male Flare x 1/2" Female Flare), this Allin Liquid Eye unit utilizes a unique magnifying "see-thru" feature. The central dot on the high-visibility tube magnifies when the line is completely full, providing a clear indication that a solid column of liquid is reaching the expansion device. Designed for HFC refrigerants and compatible with POE oils, the SG206 includes a sensitive color bar to detect trace moisture before acid formation damages the compressor. This sight glass is a direct technical equivalent to the 5916 sight glass and is rated for a maximum working pressure of 600 PSI. Built with a solid brass body and shock-resistant glass, it handles temperatures up to 500°F, making it a reliable diagnostic component for both residential and commercial HVACR service.

Key Benefits

  • Enhanced Visibility: Magnified "see-thru" dot allows for instant detection of refrigerant flash gas or bubbles.
  • Contaminant Protection: High-sensitivity color indicator provides early warning of system moisture contamination.
  • Robust Construction: Solid brass body and shock-resistant glass ensure durability under high-pressure HFC refrigeration cycles.
  • System Compatibility: Direct replacement for A-1 F5916 with 1/2" flare fittings for standard liquid line installation.
  • Wide Operating Range: Engineered to withstand peak pressures up to 600 PSI and extreme thermal conditions.

Common Questions

Where is the best location to install the SG206 sight glass?
For the most accurate diagnostics, install the sight glass in the liquid line immediately after the filter-drier and as close to the expansion valve (TXV) as possible to monitor the state of the refrigerant entering the evaporator.

What does it mean if bubbles are visible in the sight glass?
Bubbles or foaming typically indicate a low refrigerant charge, a restriction in the liquid line (such as a plugged drier), or insufficient subcooling. A clear, magnified glass indicates a full line of liquid.

Is this sight glass compatible with R410A systems?
Yes, the Supco SG206 is rated for 600 PSI, making it suitable for high-pressure R410A systems, as well as other common HFC and HCFC refrigerants.
