Detailed Description

This Denso A/C receiver drier is used in HVAC systems that require a block union style accumulator/receiver drier. It helps manage liquid and vapor refrigerant flow while the desiccant captures moisture that can damage seals, corrode internal parts, and reduce system efficiency. For Nissan and INFINITI vehicles with confirmed fitment, 478-2017 supports proper A/C service after compressor replacement, line repair, or other major system work.

This part cross-references Four Seasons 83131 for the same application.

What It Helps Address

• Moisture contamination in the A/C system
• Corrosion inside HVAC components
• Reduced cooling performance after A/C service
• Refrigerant flow instability
• Premature wear from contaminated refrigerant circuits

Installation Notes

Replace the receiver drier during major A/C service, especially after opening the system or replacing major components.
