York 028-12709-000 Teflon Seal

The York 028-12709-000 Teflon Seal is a critical HVAC replacement part designed for high-performance sealing in commercial chiller maintenance applications. Engineered from high-grade PTFE (Polytetrafluoroethylene), this compressor shaft seal provides exceptional chemical resistance and thermal stability across a broad temperature range. Its low-friction coefficient ensures minimal wear on rotating assemblies, maintaining airtight pressure boundaries within YORK centrifugal chillers. This specific York OEM gasket is machined to exact tolerances to prevent refrigerant leakage and oil migration, ensuring the integrity of the refrigeration circuit. When performing a system overhaul, utilizing this industrial PTFE seal is essential for meeting original equipment manufacturer specifications and preventing premature component failure. This centrifugal compressor seal is a direct-fit solution for technicians requiring reliable refrigeration hardware that stands up to the rigorous demands of continuous-duty industrial cooling cycles.

• Superior Chemical Inertia: Resistant to most refrigerants and synthetic refrigeration oils, preventing seal degradation.
• High Thermal Limits: Maintains physical properties under extreme discharge temperatures common in heavy-duty commercial applications.
• Low Friction Torque: Reduces heat generation at the contact point, extending the service life of the York 028-12709-000.
• Precision Fitment: Eliminates the need for field modifications, ensuring a fast and secure installation during HVACR repairs.

Is this seal compatible with R-134a and R-123 systems?
Yes, the York 028-12709-000 PTFE construction is compatible with standard HFC and HCFC refrigerants, as well as Mineral and POE oils.

Does this part require a specific lubricant during seat installation?
Standard industry practice dictates a light coating of compatible compressor oil to prevent dry-start friction, though the Teflon material is self-lubricating once operational.

Can this gasket be used in York YK or YT model chillers?
This York Teflon seal is frequently specified for use in various York centrifugal series; refer to your specific unit’s parts manual to verify the correct York 028-12709-000 application.
