Distribute air or fluid to multiple locations from a single supply source with these manifolds. They are also known as headers. They have mounting holes, so you can mount from the top or side. Aluminum manifolds are the industry standard for the most common types of applications. They are lighter in weight than other metal manifolds and have good corrosion resistance. Anodized aluminum manifolds have a black finish and nickel-plated aluminum manifolds have a shiny finish. Use a plug (sold separately) to close off any unused inlets and outlets.
