8 Loop 1-1/4" Stainless Steel Manifold w/ Flowmeter & Ball Valve (Fully Assembled)

Note:This manifold requires 16 Loop Fitting Assemblies (please see below).

Mr PEX 1-1/4 Stainless Steel Manifold is made from high quality stainless steel, and is offered in 2 through 12 loop configurations. The manifold comes mounted on brackets and it is equipped with full port ball valves provided with thermometers, manual air vents and fill/drain valves. The branch Cv value is 1.38 and the manifold body accommodates flows up to 14gpm.

The SUPPLY (upper) manifold is fitted with balancing flowmeters with readable range of 0 to 2 GPM that allow flow adjustment of each individual loop. The flow meters have a brass body and the sight glass is made from temperature and impact resistant plastic material, all components are antifreeze resistant up to a 50% mix.

The RETURN (lower) manifold, has manual on/off valves that controls the flow for each individual circuit. The manual knob can be removed to accommodate the Mr PEX actuators (part# 5120700 & 5120701).

Supply and return mains can be connected from either left or right sides. The manifold comes ready for a left hand connection. Connection from the right can be done by removing the manifold body from the brackets and flipping them over.



This manifold requires (16) Loop Fitting Assemblies:

PEX Loop Fitting Assemblies Options

• 4310500: 1/2" PEX to EK20 Loop Fitting Assembly
  This fitting will connect 1/2" PEX to a loop of the Manifold
• 4310375: 3/8" PEX to EK20 Loop Fitting Assembly
  This fitting will connect 3/8" PEX to a loop of the Manifold
• 4310625: 5/8" PEX to EK20 Loop Fitting Assembly
  This fitting will connect 5/8" PEX to a loop of the Manifold

PEX-AL-PEX Loop Fitting Assemblies Options

• 2410500: 1/2" PEX-AL-PEX to EK20 Loop Fitting Assembly
  This fitting will connect 1/2" PEX-AL-PEX to a loop of the Manifold
• 2410625: 5/8" PEX-AL-PEX to EK20 Loop Fitting Assembly
  This fitting will connect 5/8" PEX-AL-PEX to a loop of the Manifold
  

Optional Installation Accessories:

Loop End Cap

• 3610003: Manifold Loop End Cap
  These allow you to cap off a loop of the manifold if it will not be used.

Supply/Return Adapter Options

• Supply/Return Adapters

Actuators

• 5120700: Thermal Actuator for Mr. PEX Manifolds (4 Wire)
  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.

Manifold Thermometer

• 3230001: Manifold Thermometer (Box of 2)
  These display the temperature of the supply and return sides of the manifold.
