Product Description
The OEM SLI 3/8" liquid indicator (SKU 3G-CBM-01739) is a refrigeration sight glass in the SLI/SBI/SBIA series with a brass body, 3/8" ODF brazed connection, and a 22.5 mm tempered-glass window with indicator paper. It shows refrigerant flow condition and indicates moisture content in the liquid phase, with green for dry and yellow for wet; the reading range depends on the refrigerant, for example R22 dry below 30 ppm and wet above 150 ppm, and R404A dry below 20 ppm and wet above 100 ppm. Maximum ambient temperature is 80 °C, and the SLI 3/8 unit measures 119 mm in length and 0.15 kg in weight. It suits all HCFC and HFC refrigerants but not R12, R502 or ammonia.
