PEX Manifolds are an important part of hydronic floor heating systems. They're used to direct the water supply to individual branches. Radiant heating manifolds can be used in a range of installations including concrete slabs and baseboard radiators. Both supply and return manifolds are used in most systems and are available with 2 to 12 branches. All of our PEX manifolds are manufactured and tested to ensure superior performance. Component features include manual valves for balancing flow and adding indicators, air vents, drains and temperature gauges.
