Brass sight glass with moisture indicator for HVAC and refrigeration liquid lines. ODF solder and SAE flare connections. Working pressure up to 46 bar. Temperature range -40°C to +80°C. Compatible with R22, R134a, R404A, R407C, R410A, R507C.
Our Brass Sight Glass is installed after the filter drier on the liquid line to provide visual monitoring of refrigerant flow condition and moisture content. The wide-angle glass offers clear visibility, while the high-precision color-changing indicator gives an at-a-glance reading of system moisture levels.
Constructed from forged brass with a PTFE seal for leak-free performance. Available in ODF solder and SAE flare connections.
