York S1-026-34089-000 Accumulator Tank

The York S1-026-34089-000 Accumulator Tank is a critical field-service component designed for high-efficiency heat pump and air conditioning systems. Featuring a 3/4" ID connection and a 49Oz capacity, this HVAC refrigerant accumulator is engineered to safeguard the compressor's mechanical integrity by preventing liquid slugging during low-load conditions or defrost cycles. As a genuine York OEM replacement part, it maintains the specific flow rates and pressure drops required for York, Coleman, and Luxaire units. The internal U-tube assembly includes a metered oil return orifice, ensuring that compressor lubrication is maintained while trapping liquid refrigerant that could otherwise lead to valve failure. This 3/4 inch suction line accumulator is built with heavy-gauge steel to withstand the operating pressures of modern residential equipment. For technicians, ensuring this heat pump accumulator tank is properly sized and installed is essential for preventing premature compressor burnout and maintaining long-term system reliability in the field.

Key Benefits

• Prevents liquid refrigerant from entering the compressor suction port, mitigating hydraulic shock.
• Optimized U-tube design ensures consistent oil return to the crankcase.
• Direct OEM fitment for York and Johnson Controls equipment reduces installation time.
• Robust steel construction rated for high-pressure refrigerant applications.

Common Questions

Where should the S1-026-34089-000 be located in the refrigeration circuit?
This accumulator must be piped into the suction line, positioned specifically between the evaporator and the compressor to trap liquid before it reaches the suction valves.

What is the primary function of the 49Oz holding capacity?
The volume ensures the system can safely store excess liquid refrigerant during transient states, such as the switch from cooling to heating mode in heat pump applications.

Can this accumulator be used with R-410A systems?
Yes, the technical specifications and weld strength of this tank are designed to handle the higher operating pressures associated with modern R-410A refrigeration cycles.
