Moisture Indicators are designed to monitor the moisture content within the liquid line of a refrigeration system.

Also series with stainless steel body and extended copper tube connections are fully hermetic products without the use of any gasket.

See-All moisture liquid indicator combines two functions of moisture and liquid indication into a single economical product. The indicator is a porous filter paper that is sensitive to moisture. A green dark color indicates the refrigerant is dry.  A yellow color indicates the refrigerant is wet.  The indicator is formulated so that it changes color at the moisture levels generally accepted as the safe operating range. Also, one can see through the sight glass to determine refrigerant is at the proper level in the liquid line to feed the expansion device.   Each valve is factory tested to ensure positive leak-free performance.
