Rehau 281881-101 - PRO-BALANCE 1-1/4" 8 Station Brass Manifold With Gauges
A manifold for any application PRO-BALANCE manifolds make circuit balancing easy. You can visually check flow rates and adjust the circuits with the key that comes in the box. These manifolds look professional, which is important, since in most radiant heating, cooling or snow and ice melting projects, the manifold is the only piece of equipment that is visible. PRO-BALANCE manifolds provide all this and more.
