Description
The York 028-12961-004 O-Ring is a circular sealing component to maintain a tight, leak-free joint between mating parts under pressure in HVAC systems. It is placed in compressors, valves, evaporators assemblies, or refrigerant line connections. It is used in chillers, heat pumps and air conditioning systems, where consistent sealing is essential for maintaining system pressure, and efficiency. It operates as a primary sealing element in the refrigeration circuit, helping preserve refrigerant containment, regulate operating conditions, and provide support during heating, and cooling cycles.
