TruFLOW™ Manifold System
This larger-capacity manifold is an Uponor-exclusive, designed specifically for meeting the higher flow demands of commercial and snow-melting applications.
The TruFLOW Sr. manifold is made of highly reliable extruded brass and features a modular concept design to allow greater flexibility for any application. The manifold comes in 2-, 3-, 4-, 5- and 6-loop manifold segments, and is available in three versions — with balancing valves, with isolation valves and valveless.
The manifold features o-ring sealed nipples, manifold connections and end caps to ensure a leak-resistant and secure connection. It also offers a heavy-duty manifold bracket, which allows the installer to meet any site requirement with ease.

Highly reliable extruded brass body

O-ring sealed connections

Extension kits available for greater flexibility

1 1/2" NPT or copper sweat connections

1 7⁄8" i.d. for superior flow characteristics

High-loop Cv for lower pressure drops at higher flows
Connecting the Manifold
Connect the manifold with either 1 1⁄2" NPT or 1 1⁄2" copper sweat. The loop connection features an R25 thread to accommodate 5⁄8" or 3⁄4" PEX or Uponor multi-layer composite (MLC) tubing (formerly MultiCor®) fitting assemblies.
The internal diameter (i.d.) of the manifold body is 1 7⁄8" and easily
allows up to 41 gallons per minute (gpm). The loop outlets have a flow
coefficient (Cv) of 7.4 gpm.
In addition, each manifold segment comes with an insulation kit to help protect the manifold and to reduce heat loss at the manifold.
