Sight Glasses are used to determine the state of charge. For optimum performance a cooling system must have a solid column of light at the expansion valve. A sight glass provides a visual indicator of any "bubbles" in the refrigerant stream that could adversely effect performance. In general, the sight glass should be located s near the expansion valve as possible. RParts sight glasses also incorporate a visual moisture indicator which changes color if moisture is rises to an unacceptably high level.
