1 1/4″ STAINLESS STEEL MANIFOLDS FOR UP TO 5/8″ PEX & PEX-AL-PEX TUBING, 2–12 LOOPS

MrPEX® 1 1/4″ Stainless Steel manifolds achieves the highest level of long term corrosion resistance by using a bright annealed high-grade, Type 304, stainless steel with high nickel content. This creates a stable material structure with low levels of ferrite and magnetism. To eliminate the possibility of contact corrosion. The manifolds are fully assembled, ready for mounting, The supply side feature adjustable flowmeters for flows up to 1.45 gpm per loop, and the return side has balancing on/off valves, in accordance with DIN EN 1264‑4. The adjustable flow meter allows for a positive shut-off and the manual plastic cap on the return valve can be removed to accommodate a valve actuator #5120700 or #5120701. The return balancing valve disc is designed to enable exact adjustments of small flows while still being able to handle large flow with minimal resistance. The branch Cv value is 1.38 and the manifold body accommodates flows up to 14 gpm. The supply and return manifold bodies both have wells to accomodate optional thermometers, and a multi‑function swivel End Cap allowing for Fill/Drain or Vent. Each inlet of the manifold has a G 1″ thread (BSP straight metric thread) allowing for easy connections of the supply and return mains. Use only “MrPEX® Manifold Option” adapters for appropriate connection. The branches have Eurokonus (EK 20) connections, and all MrPEX® EK 20 compression fitting assemblies (PEX to EK 20 or PEX-AL-PEX to EK 20) can be used to connect tubing to the manifold.
