York 026-43375-000 Sight Glass

Ensure critical system diagnostics with the York 026-43375-000 Sight Glass, an essential OEM replacement part engineered for high-pressure refrigeration and HVAC environments. Designed primarily for York air-cooled screw liquid chillers, this sight glass with gasket provides a clear, high-visibility window into the liquid line, allowing technicians to monitor refrigerant flow and charge levels in real time. The precision-machined assembly includes a robust sealing gasket to prevent refrigerant leaks and maintain system pressure integrity under rigorous operating conditions. Weighing 0.22 lbs, this commercial HVAC sight glass is a direct-fit component that mitigates the risk of moisture contamination or low-charge oil failures by enabling immediate visual inspection of bubbles or debris in the system.

• Accurate Charge Monitoring: Facilitates instant identification of vapor bubbles in the liquid line, indicating low refrigerant or restricted filter driers.
• Precision Gasket Seal: Includes a factory-spec gasket that ensures a leak-proof interface between the glass and the chiller housing.
• Optimized Compatibility: Specifically designed for York Chiller model 42FL28 and compatible air-cooled screw units.
• Durable Construction: Built to withstand the thermal expansion and vibration typical of heavy-duty industrial HVACR equipment.

Can I reuse the old gasket when installing the 026-43375-000?
No. Reusing old gaskets often leads to micro-leaks due to previous compression sets. Always use the provided new gasket to ensure a vacuum-tight seal.

What does it mean if the sight glass shows bubbles after the system has stabilized?
Bubbles usually indicate a low refrigerant charge or a pressure drop across the liquid line components, such as a clogged filter drier. Always verify subcooling values before adding refrigerant.

Is this sight glass rated for high-pressure R-410A systems?
This part is specifically engineered for commercial centrifugal and screw chillers; always confirm the maximum working pressure (MWP) of your specific York unit before installation.
