Keep moisture and debris out of your refrigerant with the Four Seasons A/C Accumulator with Hose Assembly / A/C Refrigerant Suction Hose (MPN 55278), a direct-fit replacement for the 1986-1993 Ford Mustang. This unit is listed under both part-type names — accumulator with hose assembly and A/C refrigerant suction hose. See the Buyer's Guide tab for engine-specific coverage.
The accumulator / filter drier works as a filter, pulling moisture and contaminants out of the air conditioning system — debris that a flush cannot remove, which is why this component is replaced whenever the system is opened.
Backed by over 50 years of mobile A/C experience from Four Seasons.

What vehicles does this fit?
It is a direct-fit replacement for the 1986-1993 Ford Mustang. Check the Buyer's Guide tab to confirm the application for your specific vehicle.
What does the accumulator / filter drier do?
It acts as a filter, removing moisture and contaminants from the air conditioning system using a desiccant bag — contaminants that cannot be removed by flushing.
Are gaskets and seals included?

Why replace it when servicing the A/C system?
A leaking or open system can saturate the desiccant bag within hours, making the unit ineffective. Replacement is also required to validate the compressor warranty.
