PEX-AL-PEX Loop Fitting Assemblies Options
Optional Installation Accessories:

Loop End Cap
  • MA-ACT: Thermal Actuator for Rifeng Manifolds
    If you want to use your manifold to heat multiple zones, you can purchase return side actuators that work along side thermostats. The actuators act as zone valves to allow you to use one manifold to control the temperature in different rooms independently.
Supply/Return Adapter Options

Note: Bleeder valves that come equipped with Rifeng Manifolds are 1" BSP Thread (manifold inlet) x 3/4" BSP Thread (outlet). If your application requires you to connect to a garden hose, you will need to purchase a Mr. PEX Manifold End Cap w/ Swivel Fill-Drain Valve separately which is 1" BSP x 3/4" Hose Thread

Beware of faulty threading

Comments about 2-Loop Stainless Steel Radiant Heat Manifold:

This would be an incredible bang for you buck item but for the valve threading. Side to manifold fine (obviously very forgiving given that a gasket is employed). However, other side leaks. despite being tight enough and thread sealant properly applied a bothersome drip remains (both H/C valves). I noticed that replacement valve sets are backordered which makes me wonder if these things are irregular and folks have had to order replacement readily to replace stock sets (that come with the manifold). Then again at less that $40 for a set, perhaps you get what you pay for. Beyond the valves the manifold is well built and easy to install. Only other thing is that I think the direction are incorrect (typo) as H inlet flow adjust units in practice function opposite of the direction in term of what happens when turned counter vs clock wise.

      The manifold comes with inlet and outlet shut-off valves that each have a dial thermometer. They connect to the 1" BSP connections on the manifold, and have 1" female NPT thread for supply and return piping connections. The thread size is EK20 for the loop connections.
