1/2" PEX adapters are included by default. For other size adapters (free upgrade - 3/8" PEX, 5/8" PEX or 1/2" PEX-AL-PEX) make a note at checkout.
8-branch Deluxe Radiant Manifold Set. Brass body and components with nickel plated finish.
The following components are included in every set:
(1) Supply side radiant manifold w/ (8) flow indicators and (8) outlets for PEX tubing.
(1) Return side radiant manifold w/ (8) manual balancing valves and (8) outlets for PEX tubing.
(2) 1" threaded shut off valves w/ 1/4-turn handles - one for supply and one for return manifold (red & blue).
(2) Temperature gauges - one for supply and one for return manifold to monitor supply and return water temperatures.
(1) Float-type air vent to eliminate air from the system (air vent caps included for pressure testing purposes).
(2) All-in-one drain & fill valves with 3/4" garden hose (drain hose) connection and a cap - on each manifold.

4-branch Brass Radiant Heat Manifold Set w/ 1/2" PEX adapters The manifolds arrived quickly and were well packaged. I compared these to some of the more expensive manifolds on the market and I have to say I made the right choice. The fit/finish is very good and overall I feel a great value. Let's face it once setup your going to forget about it. I have already installed them in a on slab concrete floor and they are working very well.

Ask a Question
I'm putting in Radiant Heating in a slab on grade. It is at the long beach Wa area andwant to know if I should use a SS or a Brass Manifold. I'm on a well with soft water.
There is no significant difference between the SSM (stainless) and BSM (brass) PEX manifolds other then the material and thickness of the manifolds. The stainless steel manifolds are more appropriate for applications where water quality is under question and therefore, are more popular. Brass ones have thicker walls, more heavily-built and are overall better looking.

Can these be used with cast iron radiator heat (hot water)?
They can, if the supply temperature does not exceed 158F. Also, we strongly recommend you install a fine mesh strainer on the supply side of the manifold to prevent accumulation of sediment and rust particles (from radiators) inside the manifold. For radiators, we also suggest using 5/8" PEX instead of typical 1/2".

What's the maximum pressure these manifolds can be air tested?
General guidelines is x3 times the maximum operating pressure but no greater than 100 psi and at least 40 psi. Duration is 30 minutes minimum, 2 hours recommended. Note that initially the pressure may drop somewhat due to flexibility of PEX, but the system should become balanced within the first 30 minutes and there should be no pressure drop afterwards if there's no environment temperature change.

will these work with wirsbro 1/2 hepex
Yes, these manifolds work with all PEX and PEX-AL-PEX tubing types.
