Product Instructions
Viega Stainless IPS to CTS
Transition Coupling ½” to 2″
Viega Stainless IPS to CTS
Transition Coupling ½” to 2″
Viega products are designed to be
installed by licensed and trained plumbing
and mechanical professionals who are
familiar with Viega products and their installation.
Installation by non-professionals may void
Viega LLC’s warranty.
The IPS side of the coupling (the larger
side) must use MegaPress jaws/rings to
make presses and the CTS side of the
coupling must use ProPress jaws to make presses.
The Viega stainless IPS to CTS transition
coupling is for joining stainless steel pipe
only. It is not meant for joining dissimilar
metals such as galvanized to copper pipe.
The IPS side of the coupling must be used
with ASTM A312 pipe. The CTS side of the
coupling must be used with Propress Stainless
tubing. The pipe/tube must be smooth, free of
indentations, pits, and deformations and must be clean
and free of dirt, debris, rust, scale, oil, and grease.
-
Cut piping at right angles using displacement type
cutter or fine toothed steel saw. -
Keep end of pipe/tube a minimum of 4″ away from
the contact area of the vise to prevent possible
damage to the pipe/tube in the press area. -
Remove burr from inside and outside of pipe/
tube and prep to proper insertion depth using a
preparation tool or fine grit sandpaper. -
Illustration demonstrates proper fit of the
components inside the press hub. -
Mark proper insertion depth. Improper insertion
depth may result in an improper seal. The depth
marking shall be visible on the completed assembly

6 While turning slightly, slide fitting onto pipe/tube to the
marked depth. End of pipe/tube must contact stop.
Warning!
Keep extremities and foreign objects away
from press tool during pressing operation
to prevent injury or incomplete press.
To make an IPS press connection (larger side)
7 Viega MegaPress stainless ½” to 1″ fitting
connections must be performed with MegaPress
jaws. See pressing tool’s Operator’s Manual for
proper tool instructions.
8 Open the MegaPress jaw and place at right angles
on the fitting. Visually check insertion depth using
mark on piping.
9 Start pressing process and hold the trigger until
the jaw has engaged the fitting.
10 Viega MegaPress 1¼” to 2″ fitting connections must
be performed with MegaPress rings and V2 actuator.
See Operator’s Manual for proper tool instructions.
11 Open MegaPress stainless ring and place at right
angles on the fitting. MegaPress ring must be
engaged on the fitting bead. Check insertion depth.
12 Place V2 actuator onto MegaPress ring and
start pressing process. Hold the trigger until the
actuator has engaged the MegaPress ring.
To make a CTS press connection (smaller side)
13 Insert appropriate Viega ProPress jaw into the press
tool and push in, holding pin until it locks in place.
Warning!
Keep extremities and foreign objects away
from press tool during pressing operation
to prevent injury or incomplete press.
14 Open the jaw and place at right angle on the
fitting. Visually check insertion depth using mark
on tubing.
15 Hold trigger on press tool until press jaws have
fully engaged the fitting. Jaws will automatically
release after a full press is made.
16 After pressing, open the jaw and remove the
press tool.
17 Upon completion of the press, release the jaw/ring
from fitting. Remove product instruction label from
fitting to indicate that presses have been completed.
Pressure Testing with Smart Connect®
Unpressed connections are located by pressurizing
the system with air or water. When testing with water
the proper pressure range is 15 psi to 85 psi. When
testing with compressed air the proper pressure range
is ½ psi to 45 psi maximum. If testing with compressed
air, use an approved leak-detect solution. Following a
successful pressure test, the system may be pressure
tested up to 200 psi with air or up to 600 psi with water.
Testing for unpressed connections using
Smart Connect is not a replacement for
pressure testing requirements of local
codes and standards.
CAUTION!
It is the responsibility of designers of
piping systems to verify the suitability
of type 304 or 316 stainless steel piping system
and its sealing elements for use with the intended
fluid media. The fluid’s chemical composition, pH
level, operation temperature, chloride level, oxygen
level, and flow rate and their effect on AISI type
304 or 316 stainless steel must be evaluated by
the material specifier to confirm system life will be
adequate for the intended service. Failure to do
so may cause serious personal injury or property
damage. Contact Viega Technical Services for
questions and approvals.
