Sporlan 700299 SA-14S Moisture/Liq Indicator

The Sporlan 700299 SA-14S is a high-performance See-All moisture liquid indicator engineered for demanding commercial refrigeration and air conditioning applications. Featuring a 1/2 ODF solder connection, this dual-purpose sight glass allows service technicians to monitor refrigerant levels and moisture saturation simultaneously. The SA-14S moisture indicator utilizes a highly sensitive chemical salt on porous filter paper that changes from dark green (dry) to a distinct yellow (wet), providing a reliable visual diagnostic for system health. Designed with a maximum working pressure of 650 psi, this unit is compatible with various refrigerants, including R-410A, R-134a, R-404A, and R-407C. The Sporlan See-All features extended copper-plated steel fittings, allowing for installation without disassembly, as the design effectively manages heat transfer during the brazing process to protect the internal moisture indicator element. The large sight glass provides a clear view to detect bubbles, indicating low refrigerant charge or liquid line restrictions, ensuring your systems operate at peak efficiency.

• Dual-Function Diagnostics: Provides simultaneous liquid line clarity monitoring and moisture detection to help prevent compressor failure.
• Multi-Refrigerant Compatibility: Accurately calibrated for R-410A moisture level detection as well as other common HFC and HCFC refrigerants.
• Technician-Friendly Installation: Extended 1/2 ODF fittings allow for direct brazing without the risk of damaging the internal sensing element.
• Reversible Color Change: The Sporlan sight glass indicator is fully reversible, responding immediately as moisture levels are reduced by filter-driers.
• High Pressure Resilience: Rated for a 650 psi maximum working pressure, meeting the safety requirements of modern high-pressure systems.

Is the moisture indicator element replaceable?
Yes, the Sporlan 700299 features a replaceable indicator element (K-SA-4 kit), allowing you to refresh the sensor without removing the entire body from the line.

Why is the sight glass yellow right out of the box?
The sensor is highly sensitive to atmospheric humidity. It is common for the element to appear yellow until it is installed and the system has been properly evacuated and charged with dry refrigerant.

Should I disassemble the SA-14S before brazing it in?
No, the 1/2 ODF solder fittings on this model are extended to prevent heat damage to the glass and sensor, making disassembly unnecessary for standard brazing procedures.
