The Smart Connect feature test
is not a substitute for local code
required pressure testing. The final
pressure test is to be carried out in

15.5 Press Connections
The pressing process provides a
simple, safe and reliable means of
connecting copper tubing for fuel gas
systems with ProPressG fittings as
shown in figure 15.2.
15.6 The Connection Process
The pressing process produces a
permanent joint between the press
fitting and the tubing in a matter of
seconds. For ProPressG fittings 1/2"
to 2", this is achieved by creatin g a
hexagonal indentation in front of and
behind the HNBR sealing element on
the press fitting. At the same time,
the pressing process reshapes the
fitting to encapsulate the sealing
element (Fig. 15.3). This technology
ensures a permanent connection.
