10. SEAPRESS (METRIC Cu-Ni-Fe) FITTINGS 15 MM – 108 MM
10.1 Tube Selection
Viega Seapress fittings are compatible
15mm through 108mm metric seamless
drawn tubes consisting of a corrosion
resistant copper-nickel wrought alloy
material.
All copper-nickel tubing that is to
be used with the Seapress copper-
nickel fittings must comply with the
requirements of DIN 86019.
10.2 Handling Instructions
Seapress components shall be free
from dirt, debris, scaling, or items that
may interfere with the sealing element
and the press connection.
Seapress sealing elements are to be
visually inspected prior to installation to
ensure the seal is intact and properly
located within the fitting.
10.3 Welding Near Seapress
Fittings
When welding near a Seapress
connection, the installer must remain
at least three feet away from the
connection to prevent damage to the
sealing element.
If three feet is not possible, the installer
should take precautions to keep
the Seapress connection cool while
welding. These include:
• Wrapping the connection with a cold
wet rag
• Fabricating welded connections prior
to installing the pressed fitting making
sure the tube has cooled before
installing the fitting
• Consistently applying “spray type"
spot freezing
10.4 Rotated a Pressed Fitting
Once a Seapress fitting has been
pressed it can be rotated (not by
hand), but once rotated more than
five degrees, the fitting must be
re-pressed to restore the resistance
to rotational movement.
