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.
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.

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.
Anodized 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. These manifolds are anodized for a black finish.
316 stainless steel manifolds have excellent corrosion resistance and can handle fuel, gasoline, coolant and other harsh substances.

Straight-Flow Junction Blocks
Use these junction blocks to organize and separate multiple lines in your system. They have threaded holes that allow air, water, or hydraulic fluid to flow straight through the block. They have mounting holes, so you can mount from the side.
Anodized aluminum junction blocks are lightweight with good corrosion and wear resistance.

Shatter-Resistant Sights
The window and body are made from a single piece of plastic, making these sights more shatter resistant than sights with a glass window. They are not rated for pressure.

Pressure Test Fittings
Check pressure without permanently installing a gauge. Fittings have an NPT male connection for installation in your pipe or tank. Wrench-tighten the fitting onto your equipment, then insert the gauge adapter (sold separately) into the fitting. Connect gauge adapters to gauges with 1/4 pipe size NPT male threads.
