Four Seasons A/C Receiver Drier P/N:33334

Keep the air conditioning refrigerant clean and dry with the Four Seasons A/C Receiver Drier (MPN 33334), a steel filter drier that installs as a direct-fit replacement on the 1985-1986 Freightliner FLC112, the 1981-1986 Freightliner FLC120, and the 1981-1986 Freightliner FLT086. Mounted on the high side, it acts as a filter — removing moisture and contaminants from the A/C system that cannot be flushed out — while its internal desiccant bag absorbs moisture that would otherwise damage system components.

• Steel filter drier: built with quality welds for a durable, leak-free design.
• Desiccant absorption: uses high-quality desiccant to draw moisture from the refrigerant; a leaking or open system can saturate the bag within hours, so replacement matters whenever the system is opened.
• Installation hardware: the necessary gaskets, o-rings and seal are included for the fit.
• System protection: filters out contaminants that flushing cannot remove, helping protect the compressor and other A/C components.

Backed by Four Seasons' decades of mobile A/C experience, this drier should be replaced any time the system is serviced, and doing so is required to validate the compressor warranty. See the Buyer's Guide tab for full engine-level fitment.
