The Goodman 0162L00025 Bi-Flow Filter Drier is a genuine OEM refrigerant-circuit component for the DCC300XXX4VVXCAA packaged unit. A bi-flow drier filters moisture, acid, and particulate from the refrigerant in both directions of flow, making it ideal for reversing (heat-pump-capable) systems. Replacing the drier whenever the sealed system is opened is essential — it protects the metering device and compressor from contamination that causes restrictions and acid burnout.
The OEM 0162L00025 matches the factory connection sizes, desiccant capacity, and flow rating. A generic drier of equivalent tonnage and connection size can work, but mismatched capacity or fittings can restrict flow or complicate brazing. For a guaranteed fit, choose OEM.
Advanced (4/5). This is a sealed-system repair: an EPA-certified technician must recover the refrigerant, braze the drier in with the correct flow-direction arrow, pull a deep vacuum, and recharge to spec. Not a DIY part — install only as part of professional refrigerant service.
