Keep your Peterbilt's air conditioning system dry and clean with the Four Seasons A/C Receiver Drier / Filter Drier (MPN 33541), a steel filter drier that installs as a direct-fit replacement across a wide range of Peterbilt trucks — including the 1977-1978 and 1993 200, the 1987-1993 224, the 1981-1988 359, the 1981-1993 362, and the 1986-1993 379. Many more models are covered, so see the Buyer's Guide tab for the full list of years and models.

  • Filters moisture and contaminants: acts as a filter that removes moisture and contaminants from the A/C system — debris that flushing cannot remove, which is why replacing the drier is essential.
  • High-quality desiccant: absorbs system moisture through a desiccant bag for appropriate absorption.
  • Steel build with quality welds: welded for a durable, leak-free design.
  • Install hardware included: ships with the necessary gaskets, o-rings and seal for installation.

A leaking or "open" system can saturate the desiccant bag within a few hours, leaving the drier ineffective, so it should be replaced any time the system is opened or serviced. Replacing the receiver drier is also required to validate compressor warranty. Backed by Four Seasons' decades of mobile A/C experience.
