This is the drain outlet kit for PolarCool 36" Pro portable evaporative coolers with the 2" drain opening — it replaces the threaded outlet, washer, nut, and cap so your reservoir empties fully and seals tight between service cycles.
The Pro 2" Drain Assembly is a genuine PolarCool replacement part built for the drain hardware on 36" Pro portable evaporative coolers. It's meant for facilities running these units in warehouse cooling, industrial HVAC support, and outdoor cooling applications where fast reservoir drainage during servicing matters.
