Keep moisture and debris out of your air conditioning system with the Four Seasons A/C Receiver Drier / Filter Drier 33533, a steel replacement drier for a range of heavy-duty Freightliner and Peterbilt trucks. It drops in as a direct-fit replacement across the listed applications, including the 1994-1996 Freightliner FLB, 1990-1996 Freightliner FLC112, 1991 Freightliner FLC120, 1991-1996 Freightliner FLD112 and 1990-1996 Freightliner FLD120, plus Peterbilt 220 (2007, 2010, and 2013-2014), 270 (2001-2003), 320 (1994-2014), 357, 377, 378 and 379 (1993-1999), 375 (1993-1996) and 385 (1995-1999). See the Buyer's Guide tab for the full list and engine details.

  • Filters and dries: acts as a filter, removing moisture and contaminants from the A/C system that cannot be removed by flushing.
  • Desiccant absorption: uses a desiccant bag to absorb moisture from the system.
  • Leak-free design: quality welds for a durable, leak-free steel build.
  • Install-ready: necessary gaskets, o-rings and seal are included.

Replacing the receiver/filter drier is required to validate compressor warranty and it should be replaced any time the system is opened or serviced, since a leaking or "open" system can saturate the desiccant and leave the drier ineffective.
