Sporlan 700611 SA-217 Sight Glass

The Sporlan 700611 SA-217 Sight Glass is a critical moisture and liquid indicator designed for large-capacity commercial refrigeration and air conditioning systems. This veteran-grade component features 2 1/8" ODF solder connections, allowing for direct installation into the liquid line to monitor refrigerant charge and system dehydration levels. The See-All moisture indicator utilize a single, high-sensitivity indicator element that remains dark green when the system is dry and shifts to bright yellow if moisture is detected, providing technicians with clear, actionable diagnostics. Use this refrigerant sight glass to identify flash gas caused by liquid line restrictions or a shortage of refrigerant, ensuring the metering device receives a full head of liquid. Engineered for durability, the Sporlan SA-217 is rated for a maximum operating pressure of 650 psi and is compatible with modern refrigerants, including R-134a, R-22, R-404A, R-407C, R-410A, and R-507. Its extended copper fittings simplify the brazing process, protecting the internal glass-to-metal seals from excessive heat during installation.

• Dual Functionality: Simultaneously monitors for moisture contamination and verifies a solid column of liquid at the expansion valve.
• Universal Calibration: Single-color indicator paper is accurately calibrated for multiple refrigerants, eliminating the need for multiple indicator types.
• Superior Visibility: Features an extra-large crystal clear sight glass and a protective cap to keep the viewing area free of debris and grease.
• Simplified Installation: The 2-1/8 inch ODF connection with extended fittings allows for easier brazing without disassembly.
• Field Serviceable: The indicator element is protected by a filter pad and screen and can be replaced using the K-SA-4 kit if required.

• What does a yellow indicator mean in a Sporlan sight glass? A bright yellow indicator signifies a "wet" condition, meaning moisture levels have exceeded safe limits for the specific refrigerant and temperature.
• Is the SA-217 compatible with high-pressure refrigerants? Yes, with a 650 psi pressure rating, it is fully suitable for R-410A systems and other high-pressure applications.
• Where should this moisture indicator be installed? For the most accurate diagnostics, install the SA-217 in the liquid line immediately after the filter-drier and before the expansion valve.
