Detailed Description

Four Seasons 33531 is an A/C receiver drier designed to support refrigerant cleanliness and moisture removal in automotive HVAC systems. The steel body measures 3.000 inches in diameter and 6.500 inches in length, with 3/8-inch inlet and outlet connections. It uses male insert O-ring fittings and includes a non-replaceable desiccant element, along with a sight glass for system inspection.

This part cross-references Bosch 13353 and Carlson 7125 for the same application. For buyers searching by vehicle, Four Seasons 33531 is a relevant option for Ford F-150 and Chevrolet Silverado A/C receiver drier replacement searches when the original system uses this style of connection and service-port layout.

What It Is Used For

  • Removing moisture from the A/C refrigerant circuit
  • Filtering contaminants in the receiver drier section
  • Replacing a leaking or saturated receiver drier
  • Restoring proper A/C system service access through the service port
  • Addressing sight-glass inspection needs during HVAC service

Installation Notes and Tips

Verify the inlet and outlet size, fitting style, and overall body dimensions before installation. Replace the O-rings with the included green seals during service, and evacuate the system before recharging refrigerant. Because the desiccant is not replaceable, install the drier only after the system has been opened and repaired to reduce moisture exposure.

For fitment-based searches, this part is commonly referenced for Ford F-150 and Chevrolet Silverado receiver drier replacement applications. Confirm the vehicle’s original receiver drier configuration, switch-port requirement, and service-port layout against the existing unit before ordering Four Seasons 33531.

Quality Assurance

Four Seasons 33531 is a new replacement part that meets or exceeds OEM requirements. The Four Seasons Filter Drier product line is built for automotive HVAC service where correct fit, sealing, and moisture control are critical to system performance.
