Keep moisture and debris out of your A/C loop with the Four Seasons A/C Receiver Drier (MPN 33394), a steel filter drier that drops in as a direct-fit replacement for the 1973-1980 Mercedes-Benz 450SL. It acts as a filter that removes moisture and contaminants from the air conditioning system — the kind of contaminants that flushing alone cannot clear, which is why replacing the drier when the system is serviced is essential.

  • Steel filter drier: A steel housing with quality welds for a durable, leak-free design.
  • Desiccant absorption: High-quality desiccant absorbs moisture from the system; note that a leaking or "open" system can saturate the desiccant within a few hours, making the drier ineffective.
  • Install hardware included: The necessary gaskets, o-rings and seal are included for easier installation.
  • Backed by experience: Produced in an ISO/TS16949 & ISO14001 certified facility, backed by over 50 years of mobile A/C experience.

Replacement of the receiver/filter drier is required to validate compressor warranty and should be replaced any time the system is opened for service. For engine-level applications, see the Buyer's Guide tab for the full list.
