Keep your air conditioning system dry and clean with the Four Seasons A/C Receiver Drier 33399, a steel filter drier that drops in as a direct-fit replacement for the 1978-1985 Mercedes-Benz 300SD, 1984-1985 380SE, 1982-1983 380SEC, 1981-1983 380SEL, 1984-1985 500SEC, and 1984-1985 500SEL. See the Buyer's Guide tab for the full application details.

The receiver drier filters the refrigerant, using a desiccant bag to absorb moisture and trap contaminants that flushing alone cannot remove — which is why it should be replaced whenever the system is opened or serviced.

  • Steel construction: a steel filter drier built with quality welds for a durable, leak-free design.
  • High-quality desiccant: a desiccant bag absorbs moisture from the system for appropriate contaminant and moisture control.
  • Installation hardware included: the necessary gaskets, o-rings, and seal are supplied for easier installation.
  • Backed by experience: produced in an ISO/TS16949 and ISO14001 certified facility, backed by over 50 years of mobile A/C experience.

Because a leaking or open system can saturate the desiccant bag within a few hours, replacing the drier helps restore proper filtering and is commonly required to validate compressor warranty coverage when the system is serviced.
