Product Description
Danfoss SGP 19 N refrigerant sight glass with N-type moisture indicator, 3/4 in (19 mm) flare (SAE) connections on both ends, code 014L0166. Brass body and brass flare connections. The fused-glass window shows the liquid-line refrigerant flow (bubbles = undercharge / non-condensables) while the colour-change N indicator reads system moisture content (green = dry, yellow = wet). Max working pressure 52 bar (754 psig), media temperature -50 to 80 C (-58 to 175 F). For HFC / HFO / CO2 (R744) and hydrocarbon-blend liquid lines. EAN 5702428818872.

Compatibility & Fitment
Liquid-line moisture-indicating sight glass with flare connections. Select by line size and connection type (flare vs solder ODF). N indicator suits HFC / HFO / CO2 and common hydrocarbon-blend refrigerants; verify the moisture end-point against the specific refrigerant/oil. Not a shut-off device.
