TechData
Scope
This product specification designates the requirements
for Viega PureFlow PolyAlloy PEX Crimp fittings and
black copper crimp rings to be used as connections
for ViegaPEX tubing in ⅜", ½", ¾" and 1" sizes. These
fittings are approved for use with ASTM Standard F876
PEX tubing.
Materials
All PolyAlloy PEX Crimp fittings are manufactured from a
polysulfone/polyphenylsulfone blended polymer (Acudel).
The material is listed with NSF International for potable
water contact. PolyAlloy PEX Crimp fittings exhibit
excellent resistance to the corrosive effects of water
and are well suited for hot water applications. The black
copper crimp rings are manufactured from UNS C10200
or UNS C12200 copper alloy. Rings are annealed to
35-45 Rockwell 15T scale for ease of crimping. The black
coating is not a paint but a surface treatment which does
not add to the dimensions of the ring.
Marking and Certification
PolyAlloy PEX Crimp fittings are marked with the F2159
ASTM Standard and the NSF-pw mark indicating third
party certification by NSF International. Rings are marked
with SDR-9 and/or PEX, F1807 and manufacturer’s
mark. NSF conducts random on-site inspections of Viega
manufacturing facilities and independently tests PureFlow
PolyAlloy PEX Crimp fittings for compliance with physical,
performance, and toxicological standards.

PureFlow PolyAlloy PEX Crimp Fittings and Crimp Rings for ViegaPEX
and ViegaPEX Ultra SDR-9 Cross-linked Polyethylene (PEX)
Recommended Uses
PolyAlloy PEX Crimp fittings and black copper crimp
rings are intended and recommended for use in potable
water distribution systems with ViegaPEX and ViegaPEX
Ultra tubing meeting the requirements of ASTM F876 .
Maximum design temperature and pressure ratings are
160 psi @ 73°F and 100 psi @ 180°F. For information on
other hot and cold applications not listed here, consult
with your Viega representative.
Handling and Installation
PolyAlloy PEX Crimp fittings are corrosion and impact
resistant. However, they are still softer than metals and
must be protected from UV exposure and volatile organic
compounds (VOCs) 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.
