1
Cut stainless steel tubing only with an
approved stainless steel pipe cutting tool.
Cut the tube square using a displacement-
type cutter or fine toothed saw.
Warning!
Keep extremities and foreign objects
away from press tool during pressing
operation to prevent injury or
incomplete press.
2
Deburr inside and outside of the tube to the
proper insertion depths to prevent cutting
sealing element. Use a wire brush, Scotchbrite
pad, sand cloth, or sandpaper to remove loose
dirt and rust particles from the pressing area.
3
Check the sealing element, separator ring,
and grip ring for correct fit. Do not use oils
or lubricants. Use only Viega ProPress shiny
black EPDM for 316 or dull black FKM for
304 sealing elements.
4
Mark the proper insertion depth as indicated
by the Viega ProPress Stainless XL Insertion
Depth Chart. Improper insertion depth may
result in an improper seal.
5
While turning slightly, slide press fitting onto
tubing to the marked depth. End of tubing
must contact stop.
6
Press Viega ProPress Stainless XL fittings with
Viega ProPress XL-C rings and V2 ACTUATOR.

7
Open XL-C ring and place at right angles
on the fitting. Ensure that the XL-C ring is
engaged on the fitting bead.
8
With V2 actuator inserted into the press
tool, open the V2 actuator. Connect the V2
actuator to the XL-C ring. Look at insertion
depth mark on the tube to make sure that
the tube is properly inserted into the fitting.
For use only with Viega stainless steel tubing

Do not use rings intended for 2½" to
4" Bronze fittings.
9
Hold the trigger until the actuator has
engaged the XL-C ring.
10
Upon completion of the press, release the V2
actuator from XL-C ring. Remove the XL-C ring
from fitting. Remove product instruction label from
fitting to indicate that press has been completed.
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 and 316 stainless steel pipe 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.
Cut tubing a minimum of four inches
away from the contact area of the
vise to prevent possible damage to
the tubing in the press area.
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.
