York 028-12961-015 O Ring

The York 028-12961-015 O-Ring is a critical OEM sealing component engineered for high-pressure HVAC, refrigeration, and industrial chiller applications. Specifically utilized in York YR chillers and compressor oil-cooler assemblies, this 0.739 ID x 0.070 thick Neoprene seal provides the chemical resistance and elastomeric compression necessary to maintain leak-proof integrity in fluid or refrigerant-handling systems. Designed to fit 7/8 inch size connections, it is a standard replacement in oil return lines, thermal expansion valves, and variable orifice valve assemblies, replacing older part numbers like 208V14.

For veteran technicians, the 028-12961-015 is the preferred choice to prevent vacuum loss and oil seepage during proactive preventive maintenance. Utilizing genuine York parts ensures strict adherence to factory-specified tolerances, which generic seals often fail to meet under extreme thermal cycling. When performing a rebuild or replacing a solenoid valve o-ring, this component ensures a perfect seat in the groove, preventing the common issue of seal twisting or premature gas bypass failure.

• Neoprene construction provides superior resistance to compressor oils and common refrigerants like R-123 and R-134a.
• Precision 0.739-inch inside diameter ensures an airtight seal in 7/8" ORFS and valve flange connections.
• Reduces the risk of unplanned downtime by maintaining seal integrity within high-vibration industrial environments.
• Direct York OEM replacement simplifies maintenance during refrigerant charge recovery and system overhauls.

What systems are compatible with the York 028-12961-015?
This seal is primarily found in York YR and YS chiller families, specifically within oil coolers, compressor discharge assemblies, and hot gas bypass valves.

Can this O-ring be used with POE and mineral oils?
Yes, the Neoprene material used in this HVAC sealing component is compatible with most standard refrigeration lubricants found in York industrial equipment.

What is the proper installation procedure to prevent leaks?
Technicians should clean the groove thoroughly, use a generous amount of compatible compressor oil on the seal, and ensure the ring is not twisted during seating to avoid early failure.
