York 5023029 O-Ring

The York 5023029 O-ring is a precision-engineered sealing component designed specifically for the sight glass assembly in industrial chiller systems. In the field, we rely on this York replacement O-ring to maintain a hermetic seal against high-pressure refrigerants, preventing costly leaks and moisture contamination. This 5023029 part is fabricated from high-grade elastomeric materials compatible with standard HVAC oils and refrigerants, ensuring it maintains its compression set even under extreme thermal cycling. When performing chiller maintenance or a full system overhaul, replacing the sight glass seal is a critical step to ensure accurate refrigerant level monitoring without risking structural bypass. This HVAC refrigeration seal provides the exact tolerances required for York centrifugal and screw chiller models, offering a reliable fit that generic alternatives often fail to achieve during high-vibration operation.

• OEM Precision: Specifically designed for York sight glass housings to ensure a leak-proof fit.
• Chemical Compatibility: Material composition is resistant to degradation from common refrigerants and lubricants.
• High Pressure Rating: Optimized for industrial cooling applications where seal integrity is paramount.
• Enhanced Durability: Provides excellent resistance to thermal expansion and contraction.

Where is the York 5023029 O-ring used?
This O-ring is primarily utilized in the sight glass assembly of York centrifugal and screw chillers to seal the viewing port against the main refrigerant circuit.

Can this seal be used with R-134a and R-123 systems?
Yes, the material specifications for the 5023029 are compatible with most standard high-pressure and low-pressure refrigerants used in industrial York equipment.

Is it necessary to replace the O-ring every time the sight glass is removed?
Standard field practice dictates replacing the seal whenever the assembly is disturbed to prevent leaks caused by the O-ring taking a permanent set or being pinched during re-installation.
