Four Seasons A/C Accumulator with Switch Port

The Four Seasons A/C Accumulator with Switch Port is a replacement air conditioning accumulator (also called a receiver drier or suction accumulator) that restores reliable cooling performance in your vehicle's A/C system. It is installed on the low-pressure side of the system. It protects the compressor by collecting liquid refrigerant and keeping it from reaching the compressor.

Key Features:

• Moisture removal: Contains desiccant that absorbs moisture in the refrigerant circuit. This helps prevent corrosion, freeze-ups and premature component wear.
• Compressor protection: Holds back liquid refrigerant and oil, then meters them back to the compressor as vapor.
• Switch port: Includes a port for the A/C pressure or cycling switch, so the original switch can be moved to the new unit.
• Replacement design: Built to match the form, fit and function of the original equipment part for a straightforward installation.
• Quality construction: Four Seasons is a well-known brand in the aftermarket A/C and engine cooling industry.

Replace the accumulator whenever the A/C system is opened for major repair, such as a compressor replacement. Doing so helps protect the new components and supports long-term system performance. Follow standard A/C service practice, including evacuating and recharging the system with the correct refrigerant and oil.
