Polyethylene (PEX)
Scope
This product specication designates the requirements for PureFlow Bronze PEX Press ttings and stainless steel
press sleeves to be used as connections for ViegaPEX, ViegaPEX Ultra, ViegaPEX Barrier, and FostaPEX tubing in
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 ttings are cast and machined from a solid Bronze alloy. This gives the tting high
corrosion and stress crack resistance. All PureFlow PEX Press ttings are precision made to tight tolerances for a
consistent t with ViegaPEX tubing. All PureFlow PEX Press ttings meet the rigorous requirements of ANSI/NSF-61
for lead extraction.
The stainless steel press sleeves are manufactured from 304 stainless steel that will not corrode, maintaining a clean
appearance for the lifetime of the system.
Marking and Certification
PureFlow Bronze PEX Press ttings and stainless steel sleeves are manufactured and certied to the requirements
of ASTM F877. PureFlow PEX Press ttings and sleeves are marked with the size, manufacturers mark, and required
marking(s) of third party certication 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 certication organizations conduct
random on-site inspections of manufacturing facilities and independently test PureFlow Bronze PEX Press ttings for
compliance with physical, performance, and toxicological standards.
Recommended Uses
PureFlow Bronze PEX Press ttings and 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. Maximum design temperature and pressure ratings are 160 psi @ 73°F, 100 psi @ 180°F and 80 psi @ 200°F.
PureFlow Bronze PEX Press tting system components are only available from Viega and are not interchangeable
