Replace the standard push-button type spigot on a Rubbermaid cooler with this sturdy ball valve. No modifications to the cooler are necessary - simply remove the old spigot, install the kit in the stock hole, and tighten the coupler on inside of cooler. Allows you to use cooler as a mash tun or hot water tank. 3/8" outlet barb is perfect for directly attaching tubing to perform transfers. Ball-Valve and all hardware is made from stainless steel and sealing o-ring is made from high-temp, food-grade rubber. This is for replacement of Rubbermaid Cooler's stock spigots only.
