A/C Receiver Drier for 1986-2006 Mack MR & More - Four Seasons 33463

Help keep moisture and contaminants out of your air conditioning system with the Four Seasons A/C Receiver Drier / Filter Drier 33463. This steel filter drier absorbs moisture and removes contaminants that flushing alone cannot remove. It fits many vehicles, among them the 1986-2006 Mack MR, 1989-1997 Mack CH and 1991-1997 Mack CL. See the "Vehicles it fits" section for the full list and engine details. This part is listed under both names, A/C receiver drier and filter drier.

• Moisture absorption: A high-quality desiccant bag inside the drier absorbs moisture from the system.
• Filtration: Removes moisture and contaminants from the A/C system. Flushing cannot remove these contaminants, so replacing the drier is essential.
• Welded steel construction: Quality welds give it a durable, leak-free design.
• Easier installation: The necessary gaskets, O-rings and seal are included.
• Certified production: Built in an ISO/TS16949 and ISO14001 certified facility with state-of-the-art equipment and high-quality materials.

A leaking or open system can saturate the desiccant bag within a few hours, which leaves the drier ineffective. For that reason, the drier must be replaced any time the A/C system is serviced, and replacement is required to validate the compressor warranty. Four Seasons backs this drier with over 50 years of mobile A/C experience.
