2.5.9 Rotating a Pressed Fitting
Once a ProPress Stainless 󶈵tting has been pressed, it can be rotated (not
by hand), but once rotated more than 󶈵ve degrees, the 󶈵tting should be
repressed to restore resistance to rotational movement.
If the 󶈵tting is re-pressed, care should be taken to align the 󶈶at sides on
the jaw with those on the 󶈵tting.
2.5.10 De󶈶ection
The pressing process can cause de󶈶ection (angular misalignment) to
occur. When pressing Viega ProPress Stainless 󶈵ttings in a system, the
deformation of the 󶈵tting is constant. This allows for a consistent leak-free
joint every time and is a result of the pressing technique.
De󶈶ection occurs in the same way for every 󶈵tting. The 󶈵tting being
pressed will move in the direction of the jaw or ring opening.
■ Since the 󶈵tting will de󶈶ect toward the opening of the jaw or ring, the
tube end will de󶈶ect in the opposite direction.
■ By counteracting the 󶈵tting movement, one can minimize the
de󶈶ection of the 󶈵tting and ultimately the tube.
■ When using strut and clamps, de󶈶ection is minimized and nearly
eliminated depending on clamp spacing.
2.5.10.1 Controlling De󶈶ection
De󶈶ection while pressing can be minimized by utilizing the following
installation practices.
Alternate Press Directions
▶ Press one end of 󶈵tting.
▶ Make second press on other end of 󶈵tting from the opposite side.
Site conditions permitting.
Push-Pull Method
▶ Rings = Push on press tool.
▶ Jaws = Pull on press tool.
The press tool can be feathered using the trigger as needed to apply
pulling or pushing force to control de󶈶ection.
