Product Description
The OEM SLI 22 liquid sight glass (SKU 3G-CBM-01742) is a refrigeration component with a humidity indicator and low pressure drop, featuring 22 mm (7/8" ODF) solder connections and a 22.5 mm sight glass diameter. It shows refrigerant flow condition and moisture content in the liquid line, with a maximum ambient temperature of 80 °C. The humidity indicator colour reflects moisture level, with a green dry range and yellow wet range; the reading range depends on the refrigerant. Suitable for all HCFC and HFC refrigerants except R12, R502 and ammonia.
Frequently Asked Questions
What is the OEM SLI 22 liquid sight glass used for?
The OEM SLI 22 is a liquid sight glass with an integrated humidity indicator that shows refrigerant flow condition during system operation, so you can see whether the refrigerant is free of gas bubbles, and it indicates the moisture content of the liquid refrigerant. It suits all HCFC and HFC refrigerants but is not suitable for R12, R502 or ammonia.
What are the specifications of the OEM SLI 22 liquid sight glass?
The SLI 22 has 22 mm / 7/8" ODF solder connections, a 22.5 mm sight glass diameter, a maximum ambient temperature of 80 °C, and a maximum service pressure PS of 36 bar with a maximum control pressure of 39.6 bar. The body is brass with a tempered pressure-resistant glass window and copper solder fittings.
How do I read the humidity indicator on the OEM SLI 22 sight glass?
Indicator colour measures refrigerant moisture: green means dry, yellow means wet, and a fading green signals low moisture where the filter drier should be replaced. Reading ranges depend on refrigerant — for example R22 is dry below 30 ppm and wet above 150 ppm, while R404A is dry below 20 ppm and wet above 100 ppm, at 30 °C. The indicator is yellow on delivery due to air humidity and turns green once the system is charged with dry refrigerant.
