Fig. 1 Merkel Omegat OMK-S
Product description
Two-piece Merkel seal set for sealing
pistons consisting of one PTFE profile ring
and one elastomer profile ring as a pre-
load component. The seal set is designed
for heavy duty hydraulic applications.
Product advantages
The Merkel Omegat OMK-S can be
used where a piston has pressure on
both sides and is designed especially
for large diameters
Very high resistance to pressure
Design prevents twisting
Very good protection against extru-
sion
High resistance to abrasion
Good thermal conductivity
Low friction, free of stick-slip
High contact pressure due to elas-
tomer profile ring.
Application
Injection moulding machines, manipula-
tors, mills, steel hydraulics engineering,
marine hydraulics, presses, large cylin-
ders.

Design notes
Please observe our general design notes in → Technical Manual.
Gap dimension
The largest gap dimension occurring on the non-pressurised side of the seal in opera-
tion is of vital importance for the function of the seal. → Technical Manual.

The catalog details are based on the
experience of many years of research
in the development and production of
seals in the Freudenberg Group and
correspond to our current level of know-
how.
The sealing action of many catalog
products is, however, not only created
by the component itself. In many
cases – depending on the specific
application – it depends significantly on
the other parameters, such as installa-
tion point, counter surface, pressure,
operating temperature, media to be
sealed, lubrication, effects of vibration
and any ingress of dirt from outside.
These and other unknown factors in
practical use may noticeably influence
the functioning of the seals. Against this
background generalised statements
on the function of the catalog products
are not possible. Details in this catalog
merely represent general and non-bin-
ding reference values which make no
claim to be valid for every application.
We therefore recommend you to always
discuss specific applications with our
consultancy service. In the event of very
high and special loads, for example due
to aggressive media, the seal should be
selected in co-operation with us; trials to
check the functional reliability are often
indispensable.

The sealing action of many catalog products is, however, not only created by the component itself. In many cases – depending on the specific application – it depends significantly on the other parameters, such as installa- tion point, counter surface, pressure, operating temperature, media to be sealed, lubrication, effects of vibration and any ingress of dirt from outside. These and other unknown factors in practical use may noticeably influence the functioning of the seals. Against this background generalised statements on the function of the catalog products are not possible. Details in this catalog merely represent general and non-bin- ding reference values which make no claim to be valid for every application. We therefore recommend you to always discuss specific applications with our consultancy service. In the event of very high and special loads, for example due to aggressive media, the seal should be selected in co-operation with us; trials to check the functional reliability are often indispensable.
