A manifold is a wide or big pipe, or channel, into which smaller pipes or channels lead. It is a pipe fitting or similar device that connects multiple inputs or outputs to ensure efficient use of all equipment and systems. DK Hardware offers a broad selection of manifolds to meet your variety of needs. MEC Manifold Block is designed to connect two cylinders. The check keeps the two tanks equalized and allows each tank to be changed without disrupting the propane to appliances. Zurn’s EcoVantage water-conserving valves lead the industry with the highest performance levels while maximizing water savings. The Apollo PEX Manifold Ball Valves provides a single-point flow control over each outlet. These manifolds are designed for implementation within home-run type PEX piping systems eliminating the need for additional fittings or connections between the water source and the point-of-use fixture.
