2. Swedged Manifolds:
Pre-assembled manifold sections
that sweat together as needed.
3. 1’’
× 1/2" × 1’’ Reduced T-Fittings
can be soldered together forming a
complete manifold. Onix Barbs are
then soldered into the 1/2’’ fittings.
For each of the assembly options, the
smallest trunk size used must be at
least 1’’.
Other methods exist to construct mani-
folds, such as T-Drill machines or even
a standard drill press.

Mini Ball Valve
Maximum flow rate for a manifold is determined by
the velocity of the fluid. Maximum design velocity
for manifolds should be between 4
–6 ft./sec.
