Product Details

The Four Seasons Filter Drier 33274 is a steel A/C receiver drier designed to support refrigerant system cleanliness by trapping moisture and filtering contaminants before they circulate through the HVAC system. It uses a non-replaceable desiccant and includes green O-rings for sealing. With a 2.000-inch body diameter and 12.000-inch body length, this receiver drier is built for classic factory-air applications where correct fitment and reliable moisture control matter. This part cross-references UAC RD4174C and SKF 16427 for the same application.

Compatible With 1967-1968 Ford Mustang, N/A, and 1967-1968 Mercury Cougar, N/A. Four Seasons 33274 is a practical replacement for owners restoring or servicing original A/C hardware on these vehicles, especially when addressing refrigerant contamination or moisture-related system wear.

Common Uses

  • Replacing a saturated or contaminated receiver drier
  • Restoring proper moisture removal in the A/C circuit
  • Addressing poor cooling caused by restricted refrigerant flow
  • Repairing classic factory-air HVAC systems on Mustang and Cougar models
  • Supporting service work after compressor or line replacement

Installation Notes

Verify inlet and outlet fitting style before installation, since this unit uses a male insert O-ring inlet and female O-ring outlet. Confirm the system is clean and evacuated before replacing the receiver drier, and replace any contaminated seals or damaged lines as needed. Because the desiccant is not replaceable, install the unit only after the rest of the A/C system has been inspected and flushed as required.

Quality Assurance

Four Seasons 33274 is a new steel filter drier that meets or exceeds OEM specifications for the listed applications. The Four Seasons Filter Drier line is built for service replacement in automotive HVAC systems where correct sealing, moisture control, and fitment accuracy are important.
