York S1-023-21572-000 Assembly

The York S1-023-21572-000 Liquid Line Assembly is a critical OEM replacement component engineered for 17.5-inch cabinet air handlers and evaporator coils. As a direct-fit York HVAC replacement part, this assembly ensures the systemic integrity of the high-pressure refrigerant circuit, specifically within partial cased coil configurations. This liquid assembly 17.5" cab line is fabricated to meet factory tolerances, maintaining the flow characteristics required for optimal thermal expansion and heat transfer efficiency. Field technicians will find this part essential for restoring original system performance in residential split systems where the existing liquid line has suffered from fatigue, restriction, or environmental corrosion.

Constructed for high-durability performance, the S1-023-21572-000 is compatible with specific 17.5-inch models, including PC18B2AN1A, PC24B2AN1A, PC24B2AN1B, and PC30B2AN1A units. By utilizing a genuine HVAC liquid line assembly, contractors can ensure seamless brazing at connection points and eliminate the clearance issues often associated with universal or third-party tubing. This assembly is designed to withstand standard operating pressures found in modern R-410A systems, providing a reliable seal and contributing to the longevity of the compressor and metering device by ensuring a clean, unobstructed path for liquid refrigerant.

Common Questions

What cabinet size is this liquid line assembly compatible with?
This specific assembly is engineered for 17.5-inch cabinet lines. For 21-inch or other cabinet widths, a different part number is required to ensure proper alignment with the coil casing.

Which York coil models use the S1-023-21572-000?
It is commonly found in PC series coils, including models PC18, PC24, and PC30 with the 17.5-inch "B" cabinet size designation.

Does this assembly include the metering device or TXV?
This part is the liquid line tube assembly itself. While it connects to the metering components, the TXV or orifice is typically sold separately unless specified in a complete kit.
