Tradepro TP-SSGSS3 Sight Glass Moisture Indicator 3/8 Inches Sweat C X C

Product Description

The TRADEPRO TP-SSGSS3 is a hermetically sealed sight glass and moisture indicator designed for use on refrigerant lines in HVAC and refrigeration systems. This component gives technicians a clear, reliable view of refrigerant flow and moisture content directly in the line. It works with all common refrigerants, making it a versatile choice for residential, commercial, and light industrial HVAC work. The fully hermetic design keeps the internal indicator element sealed and protected from contamination, which supports long-term accuracy and dependable readings in the field. The brass body resists corrosion and holds up well in demanding installation environments. Solid copper fittings allow for standard sweat connections, so HVAC technicians can integrate this sight glass into existing copper line sets without special adapters or tools. The connection size is 3/8 inches with a C x C (copper by copper) configuration, which is common in residential and light commercial refrigerant circuits. One of the standout features of this moisture indicator is its 3 percent relative humidity sensitivity. Most paper-style moisture indicators only detect at 10 percent relative humidity, which means moisture problems can go undetected longer. The TP-SSGSS3 responds at a much lower threshold, giving technicians an earlier warning of moisture in the refrigerant circuit. The tri-color indicator uses a blue, purple, and pink color system for easy reading. Blue indicates a dry system, purple signals caution, and pink indicates the presence of moisture. The wide-angle, high-visibility window makes it easy to check the indicator status even in tight or poorly lit spaces. Accurate color calibration at low parts-per-million levels and higher operating temperatures ensures the reading stays reliable across a range of system conditions. The maximum working pressure is 680 psig, which is suitable for systems using modern high-pressure refrigerants. This sight glass is a practical tool for any HVAC technician who needs to monitor refrigerant moisture levels and system charge condition during installation, service, or commissioning.

• 3 percent relative humidity sensitivity for earlier moisture detection compared to standard 10 percent paper indicators
• Fully hermetic design with all-brass corrosion resistant body and solid copper sweat fittings for long-term reliability
• Tri-color indicator (blue, purple, pink) with wide-angle high-visibility window for fast, easy field readings
