The SharkBite 5 loop radiant heating manifold is designed to optimally distribute heating fluid throughout circuits in a closed loop heating system. The manifold ensures that flow to each circuit is precisely regulated and also controls the shut-off, venting of air from the system. The fluid is heated by a water heater or boiler and distributed by the manifold throughout the different PEX tubing circuits. The manifold has a 1 In. FNPT inlet and features integrated 1/2 In. SharkBite connections on the loop ports. The SharkBite connections make connecting the loops to the manifolds significantly easier and faster than alternative connection methods.
