13.506 - Sight glass flare for the detection of humidity x1
PLEASE NOTE: it is possible to detect the presence of humidity in the system by connecting the liquid passage sight glass between adapter F1/4 SAE x F1/4 SAE (our 88.214), supplied separately.
In the presence of humidity, the litmus paper inside the sight glass will turn pink as the outer circular section with the word “WET”.
