PureFlow Crimp Hand Tools
The Viega PureFlow Crimp connection must
always be carried out with the aid of a Viega
PureFlow Crimp tool. There are multiple
congurations of Viega PureFlow Crimp
tools that are ideal for tight spaces and
awkward locations. The compression of the
tool also allows for crimp connections to be
made in temperatures as low as -30°F.
A caliper (GO/NO GO gauge) is available
to check the calibration of the crimp tool.
A crimp is good if the GO gauge ts over
the ring and the NO GO gauge does not.
At least one connection should be
checked at the beginning and end of
each day to ensure proper crimps have
been made. Most crimp tools can be
recalibrated (refer to “Viega PureFlow
Crimp Hand Tool” on page 16).
