Product Details

This receiver drier is part of Four Seasons’ Filter Drier line, a product line focused on HVAC filtration and moisture control components. The 33372 uses a steel body measuring 2.000 in. in diameter and 12.000 in. in length, with a 12.250 in. overall depth. It is configured with a 0.375 in. inlet and outlet, green O-rings, and a switch port, while the desiccant is not replaceable.

Cross-reference part numbers for this application include UAC RD4102C and Spicer 708084. Use Four Seasons 33372 when servicing factory-air systems on the Ford Mustang, Mercury Cougar, or Mercury Montego where the original receiver drier specification matches this configuration.

Common Problems It Helps Address

  • Moisture contamination inside the A/C system
  • Reduced refrigerant system efficiency from a saturated drier
  • Debris capture in the HVAC refrigerant circuit
  • Service issues caused by worn or leaking O-ring connections
  • Restoration work on factory-air classic Ford and Mercury vehicles

Installation Notes

  • Verify inlet and outlet fitting style before installation.
  • Replace O-rings and seals as needed during A/C service.
  • Confirm the switch port and fuse plug configuration matches the vehicle setup.
  • Install only after the system has been properly evacuated and serviced.
  • Use the vehicle’s factory-air specifications to confirm fitment for the Mustang, Cougar, or Montego.

Quality Assurance

Four Seasons 33372 is a new replacement receiver drier that meets or exceeds OEM requirements for the listed applications. It is built for direct-fit HVAC service on confirmed factory-air vehicles, including 1971-1973 Ford Mustang, 1971-1972 Mercury Cougar, and 1968-1971 Mercury Montego.
