Sporlan 700093-001 Sight Glass

The Sporlan 700093-001 Sight Glass, model PSG-3MF, is a critical diagnostic component for commercial refrigeration and air conditioning systems. This See-All moisture liquid indicator features a 3/8" flare connection (Male x Female SAE) and is designed for direct installation in the liquid line, typically downstream of the filter-drier. Its primary function is to provide real-time visual monitoring of refrigerant state and moisture levels. A dark green indicator signifies a dry system, while yellow warns of elevated moisture that requires a drier core change. The PSG-3MF is engineered with a high-strength, copper-brazed steel body and a large, crystal-clear sight glass to help technicians quickly identify bubbles—indicating a refrigerant shortage or liquid line restriction. Rated for a maximum operating pressure of 650 psig, this unit is compatible with common refrigerants including R-22, R-134a, R-404A, R-407C, R-410A, and R-507. Its compact design and plated SAE fittings ensure a leak-free seal and durable performance in demanding field conditions.

Key Benefits
  • Dual-Function Monitoring: Simultaneously tracks refrigerant moisture content and liquid flow clarity to prevent acid formation and compressor damage.
  • Precise Color Calibration: Features a sensitive, chemical-salt impregnated paper element that accurately shifts from green to yellow based on relative saturation.
  • High Pressure Rating: Built to withstand 650 psig, making it suitable for high-pressure systems like R-410A.
  • Field Serviceability: The 3/8" SAE flare design allows for straightforward integration without the need for brazing in tight spaces.
  • Universal Compatibility: One indicator works across a wide range of CFC, HCFC, and HFC refrigerants, simplifying truck stock.
Common Questions

What does it mean when bubbles appear in the sight glass?
Bubbles or foaming usually indicate a low refrigerant charge or a restriction somewhere in the liquid line ahead of the sight glass. It can also occur if the liquid line is significantly undersized or if there is a lack of subcooling.

Why is the moisture indicator yellow immediately after installation?
The indicator element is naturally sensitive to atmospheric humidity. Before it is exposed to dry refrigerant, it will likely show yellow. Once the system is properly evacuated and charged, the element will transition to green if the moisture levels are within a safe range.

Where is the best location to install the PSG-3MF?
For the most accurate assessment of system health, install the sight glass in the liquid line immediately before the expansion device, but after the filter-drier. This ensures you are monitoring the condition of the refrigerant just before it enters the evaporator.
