This complete kit has everything necessary to outfit a brewing kettle or sparging vessel. 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.
