Total Flow Control Manifold. Kit includes 1 piece 1/2" modular manifold, 5 piece 1/2" in-line valves. Distribute coolant from one inlet to multiple outlets. Number of outlets can be changed simply by popping T fittings in or out of the assembly. Adding valves to a modular manifold creates the total flow control manifold. Regulate the flow from each line independently. Shut off any unnecessary lines. Made of acetal copolymer.
