PureFlow® Bronze PEX Press Fittings with Attached Stainless Steel
Press Sleeves for ViegaPEX
and FostaPEX
Scope
This product specification designates the requirements for PureFlow bronze PEX Press fittings with attached
stainless steel press sleeves and tool locator ring to be used as connections for ViegaPEX, ViegaPEX Ultra,
ViegaPEX Barrier, and FostaPEX tubing in 5/16", 3/8", 1/2", 5/8", 3/4", 1", 1-1/4" and 1-1/2" sizes as available.
The connections are to be completed with the aid of a PureFlow PEX Press Hand Tool or PureFlow PEX Press
Power Tool.
Materials
PureFlow bronze PEX Press fittings are cast and machined from a solid bronze alloy. This gives the fitting highcorrosion and stress-crack resistance. All PureFlow PEX Press fittings are precision-made to tight tolerances for a
consistent fit with ViegaPEX tubing. All PureFlow PEX Press fittings meet the rigorous requirements of ANSI/NSF-61
for lead extraction.
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 manufactured out of recycled plastic. (Stainless
steel locator rings are used for solder adapters.)

Marking and Certification
PureFlow bronze PEX Press fittings with attached stainless steel sleeves are manufactured and certified to the
requirements of ASTM F877. PureFlow PEX Press 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 PureFlow
Bronze PEX Press fittings for compliance with physical, performance and toxicological standards.
Recommended Uses
PureFlow bronze PEX Press 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 and multipurpose residential fire sprinkler systems per NFPA 13D with ViegaPEX Ultra
Black (sizes 3/4" to 2") meeting the requirements of ASTM F876 and UL 1821 (130 psi @ 120°F). Maximum design
temperature and pressure ratings are 160 psi @ 73°F, 100 psi @ 180°F and 80 psi @ 200°F. PureFlow Bronze PEX
Press 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
PureFlow bronze PEX Press fittings are cast and machined from a solid bronze alloy and precision-made to
tight tolerances. Use of these materials in hot and cold water distribution systems 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.
