Product Description

The CBM Liquid Indicator 3/8" (CRE12004) is a refrigeration sight glass from the SLI/SBI/SBIA series, featuring a brass body with 3/8" ODF connection and tempered glass window with integrated humidity indicator paper. The unit measures 119 mm in length with a 22.5 mm indicator diameter, rated to 36 bar maximum service pressure and 80 °C ambient temperature, and provides refrigerant-specific moisture detection across R22, R134a, R404a, R407c, and R507 with colour-coded transitions from green (dry) to yellow (wet). 3G Electric supplies this component for refrigeration system diagnostics and moisture monitoring across Singapore and Southeast Asia.
