York 028-12961-005 O-Ring

The York 028-12961-005 is a high-grade elastomer O-ring engineered specifically for high-pressure sealing within York centrifugal and screw chillers. In the field, technicians recognize this part as essential for maintaining vacuum integrity during standard centrifugal compressor maintenance. This specific HVAC sealing component is fabricated to withstand the chemical degradation common in systems utilizing R-134a, R-123, or modern low-GWP refrigerants and associated lubricants. When performing a teardown or routine service on industrial refrigeration gaskets, ensuring the correct durometer and cross-sectional diameter is non-negotiable to prevent costly refrigerant leaks. The York 028-12961-005 replacement provides a precise fit for flange connections and housing seals, mitigating the risks of atmospheric air infiltration or oil migration. Unlike generic alternatives, this component maintains its physical properties under extreme thermal cycling and high-vibration environmental conditions common in mechanical rooms, ensuring the long-term reliability of the equipment's primary containment system.

Key Benefits

• Engineered for full compatibility with mineral, POE, and PVE refrigeration oils.
• Resilient elastomer construction prevents compression set in high-pressure refrigeration applications.
• Critical component for maintaining ASHRAE 15 compliance regarding refrigerant leak containment and safety.
• Precision-machined dimensions ensure exact fitment for York YK and YT series chiller housings.

Common Questions

What is the primary application for the 028-12961-005? This O-ring is primarily used as a static seal in centrifugal compressor housings and large-diameter piping flanges where a reliable barrier against refrigerant loss and air ingress is mandatory.

Can this O-ring be used in high-pressure liquid lines? Yes, the material composition is designed to handle the pressure differentials found in both water-cooled and air-cooled chiller systems without losing elasticity or failing under load.

Is this part compatible with newer synthetic oils? This sealing component is specifically rated for modern HVACR environments, including systems utilizing polyolester (POE) oils known to degrade standard rubber seals.
