This is the water inlet fitting that connects your PolarCool 36" Pro cooler's float valve to the water supply line. If your reservoir isn't filling right or you've got a leak at that connection, this is the direct-replacement part you need.
The Pro Water Inlet Assembly is a genuine PolarCool component built to handle continuous water flow in demanding environments — warehouse floors, outdoor cooling stations, and industrial air cooler setups. It's a direct-fit replacement, so you're not modifying anything to make it work; you're restoring the system to factory condition. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
