Keep your A/C system clean and dry with the Four Seasons A/C Receiver Drier 33423, a steel filter drier that installs as a direct-fit replacement across a wide run of Mercedes-Benz models — the 1987-1989 260E, 1988-1993 300CE, 1987 and 1990-1993 300D, 1986-1993 300E, 1987 300TD, 1988-1993 300TE, 1992-1993 400E, 1992-1993 500E, 1994-1995 E320, 1994-1995 E420, and 1994 E500. See the Buyer's Guide tab for engine-level fitment.

The receiver/filter drier traps moisture and circulating contaminants that flushing alone cannot remove, which is why it should be replaced whenever the system is opened for service.

  • Steel filter drier: a steel housing with quality welds for a durable, leak-resistant design.
  • Desiccant absorption: a desiccant bag absorbs moisture from the refrigerant circuit; a leaking or open system can saturate the desiccant within hours and render the drier ineffective.
  • Install hardware included: the necessary gaskets, O-rings, and seal are supplied for installation.
  • Backed by experience: produced in an ISO/TS16949 and ISO14001 certified facility using state-of-the-art equipment and high-quality materials.

Replacing the drier any time the A/C system is serviced also helps validate compressor warranty coverage.
