Purge Pump Drain Kit & Adapter for Purge Pump (with Nylon Drain & Overflow Pipe) Use with Purge Pump to Reduce Mineral Build-Up In Evaporative Coolers. Replaces Adobeair SP200B
Fit perfectly in my csc641 Master Cool. Parts at the local stores did not. No issues thus far. Would be 5 stars but shipping was nearly as much at the part itself.
