Each manifold is 72 in (183 cm) L with 24-outlets at 3 in on-center, except the 2 x 1 in manifold (Art. 250850) which has 18-outlets at 4 in on-center. Outlets are 2 in L as shown. Manifolds can easily be cut to length by cutting in the center between two-outlets. Do not exceed maximum flow rates listed above. Use with Rehau® fittings and valves to assemble complete manifolds for heating application.
