- Filters the A/C system: removes moisture and contaminants that flushing cannot clear, which is why replacing the drier is essential whenever the system is serviced.
- Desiccant bag: absorbs moisture from the refrigerant circuit; a leaking or "open" system can saturate the bag within a few hours, leaving the drier ineffective.
- Installation hardware included: ships with the necessary gaskets, o-rings, seal and plug for the job.
- Quality welds: for a durable, leak-free design.
Replace the drier anytime the A/C system is opened or serviced, and note that many compressor warranties require that a new drier be installed. Backed by Four Seasons' 50-plus years of mobile A/C experience.
