Operating conditions:
Coupling nipple and coupling mechanism
must face coaxially each other before the
coupling process.
The base plates of both elements must be
guided about 2 to 3 mm before contact of the
sealing surfaces within the radial positioning
tolerance.
The coupling force between coupling nipple
and coupling mechanism resulting from
hydraulic pressure according to the formula
has to be compensated positively from the
outside.
The axially acting front seal areas must be
protected from contamination. Good results
can be archieved by rinsing and following
blowing-off with compressed air.
The sealing of the mechanism is done in the
drill base of the mounting hole. The required
surface quality in the drawing has to be kept.

Description:
Coupling elements are used to prevent leakage
when transmitting liquid or gaseous mediums
orvaccum. The coupling elements are special
compact parts, which can be installed directly
into a receiving housing. The system seal
(axial seal) between coupling mechanism and
coupling nipple acts axially. It is placed in the
coupling mechanism. This design makes it
possible to have positioning tolerances.
Depending on the seal material the coupling
elements are pressurised or depressurised
coupleable. The built-in elements are
particularly suitable for installation in
plates of multiple coupling systems.
Threaded-body elements can be directly
scewed into the fixture body, for example of
a tool change system. There, they are ideal
suitable as an interface for medium transfer.
Advantages:
£5 Space-saving installation in individual
receiving housing possible

gaseous mediums and vacuum
