3.10 Viega ProPress for Stainless ½" to 2" installation
For use only with Viega stainless steel tubing
Read, understand and follow all
instructions for installing Viega ProPress for Stainless
fittings. Failure to follow all instructions may result in
extensive property damage, serious injury or death.
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 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.

1. Cut stainless steel tubing only with an approved
stainless steel pipe cutting tool. Cut tubing at right
angle to permit proper joining with the fitting.
2. Remove burr from inside and outside of tubing to
prevent damage to the sealing element.
3. Check seal for correct fit. Do not use oils or lubricants.
Use only Viega ProPress Shiny Black EPDM or Dull
Black FKM sealing elements.
4. Mark proper insertion depth as indicated by the Viega
ProPress Insertion Depth Chart. Improper insertion
depth may result in improper seal.
5. While turning slightly, slide press fitting onto tubing to
the marked depth.
Note:
End of tubing must contact stop.
6. Insert appropriate Viega jaw into the pressing tool and
push in, holding pin until it locks in place.
7. Open the jaw and place at right angles on the fitting.
Visually check insertion depth using mark on tubing.
8. Start pressing process and hold the trigger until the
jaw has engaged the fitting.
9. After pressing, the jaw can be opened again.
CAUTION
Leak 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 maximum.
Leak testing with air can be dangerous at
high pressures. When testing with compressed air the proper
pressure range is ½ psi to 45 psi maximum. Following a
successful leak test, the system may be pressure tested up
to 200 psi with air, or up to 600 psi with water, if required by
local code requirements or project specifications.
