3.4.2
Bending pipes
Copper pipes in the sizes d 12, 15, 18, 22 and 28 can be bent cold with
commercially available bending equipment (radius at least 3.5 x d).
The pipe ends (a) must be at least 50 mm long so that the press con‐
nectors can be mounted properly.
3.4.3
Shortening the pipes
NOTICE!
Leaky press connections due to damaged material!
Press connections can become leaky due to damaged
pipes or sealing elements.
Observe the following instructions to avoid damage to pipes
and sealing elements:
– Do not use cutting discs (angle grinders) or flame cutters
when cutting to length.
– Do not use grease or oils (e. g. cutting oil).

Cut the pipe properly using a pipe cutter or fine-toothed hacksaw.
Avoid grooves on the pipe surface.

Deburring the pipes
The pipe ends must be thoroughly deburred internally and externally
after shortening.
Deburring prevents the sealing element being damaged or the that the
press connector cants when mounted. Use of a deburrer (model 2292.2)
is recommended.
