Right-Angle Flow Rectangular Manifolds
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.
Stainless steel manifolds have the best corrosion resistance of all our metal manifolds. They can handle a wider temperature range than other plastic and metal manifolds. 316 stainless steel manifolds have better corrosion resistance than 303 stainless steel manifolds to handle fuel and gasoline in addition to coolant and other harsh substances.
Use a plug (sold separately) to close off any unused inlets and outlets.

Straight-Flow Rectangular Manifolds
Unlike other manifolds, which have an inlet on either end, these have one inlet on the opposite side from the outlets. This design allows fluid or air to follow a straight path, improving flow through your system. It also frees up the ends of the manifold, so you can mount it in corners and in narrow spaces. Manifolds are also known as headers. They have mounting holes, so you can mount from the top or side.
316 stainless steel manifolds have excellent corrosion resistance. They can handle fuel, gasoline, coolant, and other harsh substances.
Use a plug (sold separately) to close off any unused inlets and outlets.

Low-Profile Hex Manifolds
When you’re short on vertical space, these manifolds are a good fit—they have outlets on the side instead of on top, so they have a lower profile than rectangular manifolds. Use them to distribute air, water, or hydraulic fluid to five locations from a single supply source. Manifolds have mounting holes, so you can mount from the top.
