Product Details

The Four Seasons 33352 accumulator is part of the Four Seasons Accumulator line, a product family focused on direct-fit HVAC service components. This unit uses aluminum construction for corrosion resistance and consistent fitment in A/C systems that require a P-nut style accumulator with no service port. The design follows OEM-style dimensions and connection points, making it a practical replacement for restoring refrigerant storage and moisture separation in the air conditioning circuit.

This part cross-references UAC RD9907C and RD10044C for the same application. It is also referenced by part number 33352 in aftermarket catalogs and interchange listings.

What It Helps Fix

• Weak or inconsistent cabin cooling
• Moisture contamination in the A/C system
• Refrigerant storage issues after accumulator failure
• Leaks at worn accumulator connections or seals
• HVAC performance loss caused by a damaged or restricted accumulator

Installation Notes

Verify the inlet and outlet fitting style, thread size, and overall dimensions before installation. Replace the O-rings with the correct green O-ring seals listed for this unit and inspect the surrounding A/C lines for wear or contamination. Because this accumulator is supplied without a service port and without a switch port, confirm that the vehicle’s original system uses the same configuration before ordering. Professional evacuation, leak checking, and recharge procedures are recommended after installation.

Quality Assurance

Four Seasons lists this accumulator as meeting or exceeding OEM specifications. The aluminum body, OE-style dimensions, and direct-fit connection design support accurate replacement in the original HVAC system layout.
