Manifolds
Copper and Brass
Manifolds
Manifolds are used to transition from
supply/return piping to Onix. Mani-
folds are usually copper or brass bod-
ies, with brass branches attached to
the sides.
Factory Supplied Manifolds
A variety of pre-manufactured mani-
fold options are available from Watts
Radiant, each specifically designed to
meet or exceed any job specification.
Among the various options are:
Custom
Tubular (Copper and Brass)
Custom Tubular Manifolds are
custom fabricated to each pro-
ject s specifications with any
number of circuits in diameters
from 1" to 6".
CazzBrass
CazzBrass Manifolds are con-
structed of cast brass and come
in either 3 or 4 circuits and cou-
ple directly to each other to form
larger manifold sets. CazzBrass
manifolds come with the follow-
ing options: blank, with flow
meters, or with balancing valves.
Stainless Steel
Stainless steel Manifolds are
constructed of tubular stainless
steel and range from 2 to 12 cir-
cuits. Each pair comes with flow
meters, circuit balancing valves
and mounted brackets.
CustomCut
(copper)
CustomCut manifolds are pre-
made manifolds that come with
12 or 16 barbs. CustomCut man-
ifolds are then cut in the field to
the specific circuit number need-
ed for each zone.
Swedged
(copper)
Swedged manifolds are pre-made
manifolds with 3, 4, or 5 circuits.
One end of a Swedged manifold
is flared so it can directly couple
to another Swedged manifold.
For example, a 3- and a 4-branch
Swedged manifold can be field
coupled to form one 7-branch
manifold assembly.
For more information on the various
manifold options see our Radiant
Catalog, or visit us on the Web at
www.wattsradiant.com.
Field Constructed
Manifolds
Some installers prefer to build their
own manifolds on the jobsite. Copper
manifolds can be made of any size
copper water pipe tubing. Manifolds
from Watts Radiant are made of type L
copper for standard use, and if request-
ed, type K copper for underground
external applications.
Caution:
Use only Watts Radiant Parts.
Do not use clamps or Onix Barbs not
supplied by Watts Radiant.
Connections made with barbs or
clamps supplied by other companies
are specifically excluded from any
Watts Radiant warranty coverage.
There are three main ways to field
construct a manifold.
1. CustomCut Manifolds:
Manifold sticks from the factory
designed to be used with any Onix
barb. Installers can purchase prefab-
ricated CustomCuts or base branch
manifolds and field solder various
combinations of barbs and mini-ball
valves as the job demands.
