York S1-026-34090-000 Accumulator Tank

As a technician, you know that protecting the compressor from liquid slugging is non-negotiable, especially in heat pump applications. The York S1-026-34090-000 Accumulator Tank is a critical suction line accumulator engineered to manage refrigerant floodback during demanding cycles. Featuring a 7/8" ID connection and a 60 oz refrigerant capacity, this field-proven component acts as a temporary reservoir, ensuring only superheated vapor reaches the compressor inlet. Its internal design facilitates a controlled oil return rate, maintaining proper lubrication while preventing the bearing washout often caused by pure liquid migration. Specifically utilized in York THJF series heat pumps and models like the THJF42S41S5A, this vertical tank is built from high-grade steel to withstand the pressure fluctuations inherent in defrost and low-ambient heating modes. For contractors, installing this HVAC replacement part is a standard preventative measure to extend the operational life of the system's most expensive component.

• Optimized Compressor Protection: Prevents liquid refrigerant from entering the suction port, eliminating the risk of catastrophic hydraulic lock.
• Managed Oil Return: Designed to meter oil back to the crankcase at a precise rate to maintain essential lubrication levels.
• Precise Fitting: The 7/8 inch inner diameter connections allow for standard brazing into existing suction lines with minimal pressure drop.
• High Capacity Storage: A 60-ounce volume provides a significant safety margin for systems with large charge variations or long-line sets.

Where should this accumulator be installed?
It must be installed in the suction line, as close to the compressor as possible, and always upstream of any suction line filter-drier to ensure maximum protection.

Is this compatible with R-410A systems?
Yes, this York OEM accumulator is designed to handle the high-pressure environments of modern R-410A residential and light commercial heat pumps.

How does this part improve heat pump defrost cycles?
By capturing the sudden surge of liquid refrigerant that occurs during the reversal of the 4-way valve, it protects the compressor scroll or pistons from impact damage.
