Detailed Product Description

The Four Seasons Filter Drier brand line is built for HVAC service parts that support refrigerant cleanliness and moisture removal in the A/C circuit. Part number 33990 uses a steel body with pad-mount inlet and outlet fittings, a 3.000-inch body diameter, and an 8.500-inch body length. It is a new, non-remanufactured A/C receiver drier with a non-replaceable desiccant design, washer not included, and no mounting bracket.

This part cross-references UAC RD7396C for the same application. It is commonly searched as an A/C receiver drier for Honda Civic HVAC repair and other vehicle-specific air conditioning service needs where the original unit uses pad-mount connections.

What It Helps Address

• Moisture contamination in the A/C system
• Debris accumulation in the refrigerant circuit
• Reduced cooling performance from a saturated drier
• Service replacement for a worn or damaged receiver drier
• HVAC repair needs on pad-mount receiver drier applications

Installation Notes and Tips

Verify pad-mount inlet and outlet fitment, switch-port configuration, and overall dimensions before installation. Replace the receiver drier whenever the A/C system has been opened for major service, and confirm that the gasket/seals are properly seated during assembly. Because the desiccant is not replaceable, install the unit as a complete service part rather than attempting internal repair.

For fitment-based searches, this part is commonly referenced for Honda Civic A/C receiver drier replacement and similar HVAC service applications. Confirm the vehicle’s original connector style and system layout against part number 33990 before ordering.

Quality Assurance
