This brass ball valve is perfect for your mash tun, hot liquor tank or brew kettle, although you will need other fittings to make it work. It's 1/2 inch FPT (female pipe thread), and should work with any standard 1/2 inch fitting, although it's designed for use with brass piping. The manual action lever is easy to operate and allows you to control the flow in increments from completely off to fully on. It can easily handle hot or even boiling water or wort. This valve is lead free. If you need help finding the right components to assemble your own all-grain or basic brewing system, we're glad to give some free advice
