3-5mm beaded orange indicating silica gel for Economy PC-TB and Brownell's R series transformer breathers.

Orange indicating silica gel is ideal in applications where visual control of moisture is required. The silica gel will turn from orange to green as it adsorbs moisture, indicating the need for replacement. Silica gel works by adsorbing and trapping moisture from the air, thus preventing condensation.
