ASSEMBLY STEPS
To achieve a good result, it is
essential to cut the pipe as clean
and perpendicular as possible
to its axis.
The pipe ends should be dry and
without grease, so that the plastic ring
will not slide on the pipe during expansion.
The size of the used expansion head must be the one corresponding to the pipe.

PEX-a ring without stop edge
Fit the plastic ring onto the pipe so that a
very small part of it (max. 1mm) is outside

loosely, expand the pipe end slightly without
the plastic ring.
Then put the ring back on
the end of the pipe sticking out
a bit (max. 1 mm).
PEX-a ring with stop edge or EVO-PLUS ring
Place the ring on the end of the pipe until the
pipe reaches the stop edge of the ring.

into the pipe, then push the trigger; the expander
head will expand and retract continuously while
the trigger is pressed. Each time the segments
retract, repeatedly and gently push the pipe inward
on the expander head several times (*) until the pipe
and ring are at level with the shoulder of the expan-
sion head. The expander head must not be pushed
inwardly of the pipe so as not to block the move-
ment auto-rotation. Finally, remove the pipe when
the segments retract and then release the trigger.

The joint can be pressurized after 30 minutes with
temperatures up to + 5 °. At lower temperatures, this
time increases according to the table below. The
maximum test pressure, which must not be excee-
ded, is 20 bar (2.0 MPa). At room temperature, after
about 6 hours, the joint will be as strong as the tube.
(*) The approximate number of expansions depends on the diameter of the pipe:
16 x 1,8: 4 16 x 2,2: 6 25 x 2,3: 8 25 x 3,5: 20
20 x 1,9: 6 20 x 2,8: 12 32 x 2,9: 12 32 x 4,4: DO NOT USE
DO NOT USE WITH PIPES 32 x 4,4!
