Four Seasons A/C Receiver Drier P/N:33319
$28.99

Keep your air conditioning system clean and dry with the Four Seasons A/C Receiver Drier 33319, a steel filter drier that removes moisture and contaminants the system can't clear by flushing. It's a direct-fit replacement across a wide range of AUTOCAR, MACK MID-LINER, PETERBILT, WHITE, and WHITE/GMC trucks — see the Buyer's Guide tab for the full application list.

  • Steel filter drier: built with quality welds for a durable, leak-free design.
  • High-quality desiccant: a desiccant bag absorbs moisture from the refrigerant for appropriate absorption; a leaking or "open" system can saturate the bag within hours, so it should be replaced whenever the system is opened.
  • Filters the system: removes moisture and contaminants that flushing cannot, helping protect the rest of the A/C circuit.
  • Installation hardware included: the necessary gaskets, o-rings, and seal are supplied.

Backed by Four Seasons' mobile A/C experience and produced in an ISO/TS16949 and ISO14001 certified facility. Replacing the receiver drier any time the system is serviced is standard practice and is required to validate many compressor warranties. Fits year/make/model applications from 1973 through 1993 — including PETERBILT 362 in both 1981-1986 and 1990-1993 — with full coverage listed in the Buyer's Guide tab.

Frequently Asked Questions

What does this receiver drier do?

It acts as a filter, removing moisture and contaminants from the A/C system through a desiccant bag. These contaminants can't be removed by flushing, so replacing the drier is essential.

Are gaskets and o-rings included?

Yes. The necessary gaskets, o-rings, and seal are included for installation.

When should I replace the receiver drier?

Replace it any time the A/C system is opened or serviced. A leaking or open system can saturate the desiccant within hours, making the drier ineffective, and replacement is often required to validate a compressor warranty.

What is this drier made of?

It's a steel filter drier built with quality welds for a durable, leak-free design.

Will this fit my truck?

It fits a range of AUTOCAR, MACK MID-LINER, PETERBILT, WHITE, and WHITE/GMC applications from 1973-1993. Check the Buyer's Guide tab to confirm the exact year, make, and model.
