Product Description

The OEM SLI 1/4 liquid gauge (SKU 3G-CBM-01738) is a refrigeration sight glass with a moisture indicator, designed for 1/4" ODF solder connections and compatible with HCFC and HFC refrigerants. It features a 22.5 mm indicator diameter and a maximum ambient temperature of 80°C. The gauge shows refrigerant flow condition and moisture content in the liquid phase, with a colour indicator that turns from green (dry) to yellow (humid).

Frequently Asked Questions

What is the OEM 1/4" liquid gauge (SLI 1/4, 3G-CBM-01738)?

It is a refrigeration sight glass with a moisture indicator, 1/4" ODF solder connections and a 22.5 mm indicator diameter. It shows refrigerant flow condition and liquid-phase moisture content in HCFC and HFC systems; it is not suitable for R12, R502 or ammonia.

What are the specifications of the OEM 1/4" liquid gauge?

The SLI 1/4 has 1/4" ODF connections, a 1/4" tube diameter, a 22.5 mm indicator diameter and a maximum ambient temperature of 80 °C. Its maximum service pressure PS is 47 bar and maximum control pressure is 51.7 bar. The body is brass with a tempered-glass sight window.

How does the moisture indicator on the OEM 1/4" liquid gauge work?

The indicator colour shows liquid refrigerant moisture content: green means dry, yellow means wet. Reading ranges depend on refrigerant — for example R22 dry below 30 ppm and wet above 150 ppm, R134a dry below 60 ppm and wet above 100 ppm, at 30 °C. A fading green suggests replacing the filter drier.

Where to buy the OEM 1/4" liquid gauge worldwide?

3G Electric supplies the OEM SLI 1/4 liquid gauge (SKU 3G-CBM-01738) worldwide, handling logistics, customs and delivery. Contact us for lead time and availability. Note: the indicator is yellow on delivery due to air humidity and turns green once the system is charged with dry refrigerant.
