The purge valve is the component at the bottom of the air dryer that expels moisture and contaminants every time the compressor reaches its cut-out pressure. Over time, the internal seals and moving parts wear out, causing constant air leaks or failure to purge. This kit contains the parts needed to rebuild the purge valve and restore proper air system drying, which helps prevent water from damaging brake valves and air lines.
