York 026-32000-000 O-Ring

The York 026-32000-000 O-Ring is a critical sealing component specifically engineered for chiller oil filter assemblies within high-tonnage HVACR systems. Designed for precise integration with York centrifugal chillers, this elastomeric seal provides a high-integrity barrier against lubricant bypass and atmospheric contamination. Given the high-pressure environment of commercial refrigeration oil systems, this O-ring utilizes premium-grade materials resistant to chemical degradation from POE oil and common HVAC refrigerants. Maintaining a positive seal in the oil circuit is essential for preventing pressure drops that can trigger low oil flow safety shutdowns. For field technicians performing routine chiller maintenance or internal oil filter replacements, this OEM-spec O-ring ensures dimensional accuracy and thermal stability, preventing leaks under cyclical load conditions. Its high-temperature resistance and cross-sectional density are optimized for the 026-32000-000 housing, ensuring consistent performance in heavy industrial applications.

Technical Benefits

• Chemical Compatibility: Formulated to resist swelling and hardening when exposed to high-viscosity synthetic oils and refrigerants.
• Precision Fit: Exact OEM tolerances prevent extrusion and nibbling under high-pressure filtration cycles.
• Thermal Stability: Retains its Shore A hardness and elasticity across a wide range of operating temperatures.
• System Reliability: Ensures an airtight seal for the oil filter canister, protecting the compressor from particulate ingress.

Common Technical Questions

Is this O-ring compatible with mineral oil and POE oil?
Yes, the 026-32000-000 is designed to maintain seal integrity regardless of the lubricant type specified for the chiller circuit.

How often should this O-ring be replaced?
Standard industry practice requires replacing this seal every time the oil filter is accessed or during annual inspection to prevent compression set leaks.

Will this fit all York chiller oil filters?
This specific part is sized for the 026-32000-000 series housing; reference your unit’s technical parts manual to confirm the specific dash number for your seal.
