Description
The York 026-42901-100 is a genuine OEM left-side oil separator engineered to maintain peak performance in York refrigeration and HVAC systems. Oil separators play a critical role in any refrigerant circuit — capturing and returning compressor oil before it can migrate downstream, protecting heat exchanger efficiency, and extending the service life of the entire system.
Why Oil Separation Matters
When compressor oil escapes into the refrigerant circuit, it coats heat exchanger surfaces, reduces heat transfer efficiency, and can starve the compressor of lubrication. The York 026-42901-100 intercepts oil-laden discharge gas, separates the oil, and returns it directly to the compressor crankcase — keeping your system running clean and efficient.
