TechData
Scope
This product specification designates the requirements
for Viega PEX Press Polymer fittings with the Smart
Connect feature and attached stainless steel press
sleeves with tool locator ring to be used as connections
for ViegaPEX, ViegaPEX Ultra, ViegaPEX Barrier, and
FostaPEX tubing in ⅜", ½", ¾", 1", 1¼", 1½" and 2" sizes
as available. The connections are to be completed with
the aid of a Viega PEX Press Hand Tool or Viega PEX
Press Power Tool.
Materials
Viega PEX Press Polymer fittings are molded from
Radel® R polymer. All Viega PEX Press fittings are
precision-made to tight tolerances for a consistent fit
with ViegaPEX tubing, exhibit excellent resistance to
the corrosive effects of water and are well suited for hot
water applications. Zero Lead throughout this publication
mean products meeting the requirements of NSF 61-G
through testing under NSF/ANSI Standard 372 (0.25% or
less percent maximum weighted average lead content). A
few states already mandate meeting those requirements
for plumbing fittings used in cooking and drinking water
systems and federal law taking effect January 1, 2014,
will make the requirements applicable to all states.
The stainless steel press sleeves incorporate three (3)
view holes and are manufactured from 304 stainless steel
that will not corrode, maintaining a clean appearance
for the lifetime of the system. The tool locator rings are
color-coded to match their appropriately sized PEX Press
hand tools and are what hold the PEX press sleeve to the
fitting, allowing it to be removed and/or replaced in the
unlikely event the sleeve is damaged during handling or
shipping (replacement sleeves and locator rings available
separately).
Marking and Certification
Viega PEX Press Polymer fittings with attached
stainless steel sleeves are manufactured and certified
to the requirements of ASTM F877. Viega PEX Press
Polymer fittings and sleeves are marked with the size,

manufacturer’s mark and required marking(s) of third-
party certification organizations. Fittings also meet the
requirements of ANSI/NSF-61 for health effects and are
suitable for contact with potable water. NSF International
and other certification organizations conduct random
on-site inspections of manufacturing facilities and
independently test Viega PEX Press Polymer fittings for
compliance with physical, performance and toxicological
standards.
Recommended Uses
Viega PEX Press Polymer fittings with attached stainless
steel press sleeves are intended and recommended for
use in potable water distribution systems with ViegaPEX,
ViegaPEX Ultra and FostaPEX tubing, and for hydronic
heating, snow melt and cooling systems with ViegaPEX
Barrier and FostaPEX tubing meeting the requirements
of ASTM F876. Viega PEX Press Polymer fitting system
components are available only from Viega and are not
interchangeable with components and tubing from
other suppliers. For information on other hot and cold
applications not listed here, consult with your Viega
representative.
Handling and Installation
Viega PEX Press Polymer fittings are corrosion and
impact resistant. However, they are still softer than metals
and must be protected from UV exposure and volatile
organic compounds (VOC’s) which can damage them.
Use of these materials in hot and cold water distribution
system must be in accordance with good plumbing
practices, applicable code requirements, and current
installation practices available from Viega. Contact a
Viega representative or the applicable code enforcement
bureau for information about approvals for specific
applications.
