Sporlan 700260 SA-14FM Moisture & Liquid Indicator

The Sporlan 700260 SA-14FM See-All is a mission-critical moisture and liquid indicator designed for high-performance HVACR systems. Built with a 1/2" male flare by 1/2" female flare connection, this sight glass allows technicians to visually confirm a full liquid line and monitor refrigerant moisture levels in real-time. The Sporlan SA-14FM features a highly sensitive, reversible color-change element that transitions from dark green (dry) to bright yellow (wet), providing precise PPM moisture detection for various refrigerants, including R-410A, R-22, R-134a, and R-404A. Capable of handling a maximum working pressure of 650 PSI, this unit integrates a protective filter pad and screen to shield the indicator from system turbulence and debris. For HVAC contractors, the See-All moisture indicator is an essential tool for preventing acid formation and compressor failure by identifying refrigerant contamination before it causes irreversible damage. Its field-replaceable indicator paper ensures long-term serviceability without removing the brass body from the liquid line.

Key Benefits:

• Dual Function Monitoring: Simultaneously verify a 100% liquid line (bubble-free) and monitor moisture saturation levels to ensure system efficiency.
• High Reliability: Features a 1/2" SAE male x female flare forged brass body, rated for 650 PSIG to withstand demanding refrigeration cycles.
• Broad Refrigerant Compatibility: Accurately calibrated for use with R-410A, R-22, R-134a, R-404A, R-407C, and R-507.
• Serviceable Design: The internal color indicator element is replaceable using a Sporlan K-SA-4 kit, allowing for easy maintenance without reclaiming the charge.
• Debris Protection: An integrated internal screen and filter pad prevent the indicator from being washed out or discolored by system contaminants.

Common Questions:

Why is my sight glass showing bubbles if the system is charged?
Bubbles in the Sporlan 700260 typically indicate a liquid line restriction, a dirty filter-drier, or a low refrigerant charge. Always check the pressure drop across the drier before assuming a leak.

What does it mean if the indicator stays yellow after a vacuum?
If the SA-14FM remains yellow after a deep evacuation, the indicator may be saturated from long-term exposure to atmosphere during installation. Most will revert to green after several hours of operation through a fresh catch-all filter drier.

Can I use this indicator with POE and mineral oils?
Yes, the Sporlan See-All series is fully compatible with both mineral oils and polyolester (POE) lubricants commonly found in modern 410A systems.
