15 Gallon 8 Port HiVis Manifold. Eliminate clutter by running just one air hose to your worksite and connect up to eight pneumatic tools at once. Equipped with a gauge to monitor working pressure and a 200 psi pressure relief valve to prevent excess pressure build-up. Top and bottom brackets allow for easy stacking or mounting to skids or other surfaces. Connect or stack multiple manifolds to handle the busiest worksites. Equipped with an excess-flow check valve which will shut air off to both tools in the event of a severed air hose or loose hose connection for additional safety.
