If the tube is angled, the straight edge of the tube lead-
ing up to the beginning of the curve's radius must be at
least twice as high as the box nut.
– Push the box nut and the profile ring onto the
tube.
– Press the tube against the stop on the connection
sleeve and tighten the box nut until the profile ring
surrounds the tube.
The tube must not turn during this process.
This may easily happen due to a significant
increase in force.
– Tighten the box nut a 1/2 turn beyond the resist-
ance point.
– Check the notch on the cutting edge:
A visible raised shoulder must fill the space in
front of the front surface of the profile ring. The
profile ring can turn, but may not shift axially.
Final assembly
– Fit the pre-assembled tube in the well-greased
threaded connector.
– Tighten the box nut until the resistance point is
felt, then do a further 1/2 turn.
Important:
hold the threaded connector using a
spanner!
Repetitive assembly
– After each time the profile ring bolt connector is
loosened, the box nut must be re-tightened until
the resistance point is felt, before receiving a fur-
ther 1/2 turn.
Important:
hold the threaded connector using a
spanner!
Unsealed profile ring connector
If the connector is not sealed, it is necessary to first
loosen the box nut until a small amount of oil flows out,
then re-tighten as directed.
The discrepancies in tightening values reduce the
resulting nominal pressure and the lifespan of the bolt
connector. This leads to leaks and tube slippage.

Taper fittings on hydraulic lines
Installation:
– Apply some oil to the O-ring on the sealing cone.
Tighten the union nut a third of a turn beyond the
point where resistance is felt.
Important:
Back up the threaded joint with a
wrench!
Any deviating tightening torques reduce the rated
pressure resistance and the service life of the screw
fitting. This results in leaks and the tube slipping out.
