5.3 Viega PureFlow Tools
5.3.1 PureFlow Press Hand Tools
The Viega PureFlow Press connection must always be carried out with
the aid of a Viega PureFlow Press tool. The hand tool incorporates a
forced compression mechanism to complete a secure connection each
time. A ratchet inside the tool prevents the tool from being opened until
the proper force has been applied to the press sleeve. A safety release
screw allows the tool to be opened at any time, but any connection made
without full tool compression must be repressed. The tool handles are
color coded to match the PureFlow Press tool locater rings.
The reduced grip feature permits one-handed operation, making the
Viega PureFlow Press system ideal for tight spaces and awkward
locations. The compression of the tool also allows press connections to
be made in temperatures as low as -4° F.
5.3.2 PureFlow Press Power Tools
The Viega PureFlow Press connection may also be carried out with a
Viega power tool. These tools are designed to make the same consistent
press as the Viega PureFlow Press hand tools. The compression of the
tool also allows press connections to be made in temperatures as low as
23° F.
5.3.3 PureFlow Crimp Hand Tools
The Viega PureFlow Crimp connection must always been carried out
by a ASTM 1807 or ASTM 2159 compliant tool. There are multiple
con󶈵gurations of the Viega PureFlow Crimp tools that are o󶈴ered by Viega
and are ideal for tight spaces and awkward locations. The compression of
the tool allows for crimp connections to be made in temperatures as low
as -30° F.
A caliper (GO/NO GO gauge) is provided 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.
