York S1-029-17738-000 Filter Drier

The York S1-029-17738-000 Filter Drier is a critical liquid line filter dryer designed for high-performance moisture and contaminant removal in HVACR refrigeration circuits. Specifically engineered for York HVAC equipment—including model D1CE120A46ECA—this 1.187" x 5" unit features a robust internal spring mechanism that ensures desiccant stability and prevents bypass under varying pressure conditions. By capturing particulates and neutralizing harmful acids, this OEM replacement part safeguards the compressor and thermal expansion valve (TXV) from premature wear and restricted flow. For contractors, installing this 1-3/16" x 5" filter drier during a refrigerant system recharge or component swap is standard practice to prevent the formation of hydrochloric and hydrofluoric acids that compromise HVAC system efficiency. Its compact copper construction and precise 1.187-inch diameter make it an exact fit for 1/4" or 3/8" liquid line configurations requiring high-capacity filtration.

• OEM Compatibility: Exact replacement for York S1-029-17738-000 and cross-reference 208U43, ensuring seamless installation without line modifications.
• Internal Spring Design: Maintains desiccant bed integrity during transport and high-vibration operation, preventing desiccant dusting and downstream clogs.
• Maximum System Protection: High-density refrigerant desiccant effectively absorbs moisture and traps debris down to 20 microns.
• Durable Shell Construction: High-pressure rated HVAC filter drier housing designed to withstand standard liquid line operating pressures.

Is this a bi-flow or uni-directional filter drier?
This model is a uni-directional liquid line filter dryer. Technicians must verify the flow arrow on the shell body points toward the metering device during installation.

Should I replace the filter drier every time the system is opened?
Yes. In accordance with HVACR best practices, the filter drier should be replaced whenever the refrigerant circuit is opened for repair, such as a compressor replacement or leak fix, to ensure the system remains dry and acid-free.

What are the physical dimensions for clearance?
The unit measures 1.187 inches (approx. 1-3/16") in diameter by 5 inches in total length, making it ideal for tight condensing unit cabinets.
