3.3.3 Clearance requirements for ProPress rings
Ensure that the space required for system pressing
tools is available if Viega ProPress fittings will be
executed immediately upstream and downstream
from ceiling penetrations.
3.3.4 Transition connections
Threaded connections
The Viega ProPress systems ½" to 4" can be
joined with off-the-shelf threaded fittings made
of non-ferrous metals.
In this regard:
1. The threaded connection is made first.
2. The press fitting is made.
This process avoids unnecessary torsion.
Flange connections
When using Viega flanges, bolt the flange end in
place prior to pressing the fitting to the tubing.
