Description

Castel sight glasses indicate by means of a visual indication whether there is moisture in the refrigerant. In the case of a yellow sight glass, moisture is present and the filter drier must be replaced. It is advisable to place a valve after the sight glass so that you can easily replace the filter drier. The presence of vapor bubbles in the sight glass indicates flash gas in the liquid line.

These HC Castel sight glasses are suitable for all HC refrigerants such as propane R290 and isobutane R600a.
