This complete kit has everything necessary to outfit a brewing mash tun. The valve and filter attach to opposite ends of the Bulkhead, allowing filtered fluids to flow from inside the vessel out the valve. Installing the bulkhead onto a container is easy. Just drill a hole 13/16″ to 7/8″ and screw on the seals and lock nuts. The entire assembly is made of durable stainless steel with high-temperature tolerant seals. And everything can be taken apart for thorough cleaning.
