Making a PureFlow Crimp Connection
Viega products are designed to be
installed by licensed and trained plumbing
and mechanical professionals who are
familiar with Viega products and their installation.
Installation by non-professionals may void
Viega LLC's warranty.

the lead free requirements of NSF 61-G

or less maximum weighted average lead content).

The tubing should be cut squarely and evenly
without burrs. Uneven, jagged or irregular cuts
will produce unsatisfactory connections. The inset
diagram shows a correctly cut tube compared
with an incorrectly cut tube.
2
Slide the crimp ring onto the tubing.

Position the ring ⅛" to ¼" from the end of the
tubing and insert the fitting into the tube to the
shoulder or tube stop
4
The ring must be attached straight. Center the
crimping tool jaws exactly over the ring. Keep the
tool at 90° and close the handles completely.
CAUTION!
Do not crimp twice.
5
When checking crimp connections with a
caliper (GO/NO GO gauge), push the gauge
STRAIGHT DOWN over the crimped ring.
NEVER slide the gauge in from the side. Do not
attempt to gauge the crimp at the jaw overlap
area. The overlap area is indicated by a slight
removal of the blackening treatment. A crimp
is acceptable if the GO gauge fits the ring and
the NO GO does not. A crimp is unacceptable
if the GO gauge does not fit the ring or the
NO GO gauge does fit. An incorrect crimp must
be cut out of the tubing and replaced. If you
check the crimp connections with a micrometer or
caliper, use the dimensions shown in the table.
Crimp outside diameters should fall within
the dimensions listed in the table below
when measured with a micrometer or caliper.
