Four Seasons A/C Accumulator with Hose Assembly,A/C Refrigerant Suction Hose P/N:55278
Keep your air conditioning dry and protected with the Four Seasons A/C Accumulator with Hose Assembly / A/C Refrigerant Suction Hose 55664. It installs as a direct-fit replacement for the 1989-1993 Ford Mustang — see the Buyer's Guide tab for engine-level fitment.
The accumulator / filter drier acts as a filter, removing moisture and contaminants from the A/C system that flushing cannot clear, which is why replacing it during service is essential. Moisture is absorbed through a desiccant bag; a leaking or "open" system can saturate that bag within a few hours and leave the unit ineffective.
Replacing the accumulator / filter drier is required to validate compressor warranty and should be done anytime the system is serviced. This part is listed under both names: A/C Accumulator with Hose Assembly and A/C Refrigerant Suction Hose.
What does this accumulator with hose do?
It acts as a filter drier, removing moisture and contaminants from the A/C system through a desiccant bag while routing refrigerant on the suction side.
Does it fit my vehicle?
It is a direct-fit replacement for the 1989-1993 Ford Mustang. Check the Buyer's Guide tab to confirm the application for your specific vehicle.

Yes. The necessary gaskets, o-rings and seal are included for easy installation.
Why replace the accumulator when servicing the A/C?
Contaminants and moisture can't be removed by flushing, and a saturated desiccant bag leaves the unit ineffective, so replacement is essential and helps validate compressor warranty.

It is produced in an ISO/TS16949 & ISO14001 certified facility with quality welds for a durable, leak-free design and high-quality desiccant for appropriate absorption.
