YORK 028-11977-000 Seal Ring

York 028-11977-000 is a special O-ring for York original factory refrigeration units. It is made of cold-resistant synthetic rubber and is suitable for the compressor interfaces, oil circuit joints and valve sealing positions of York screw and centrifugal chiller units. The product's size accuracy matches the original factory design, effectively sealing the HFC refrigerant and POE refrigerating oil within the system to prevent leakage. It also has the characteristics of resistance to high and low temperatures, oil corrosion, and aging. It is a standard replacement part for routine maintenance, disassembly and repair of the units, and must be replaced with the same model to ensure long-term sealing reliability.
