KLINGERSIL C-4106
Excellent conformity with flange
surfaces at low surface load
Basis
Synthetic fibres and cork,
bound with NBR.

Special high-pressure gasket for a wide
range of industrial applications,
also suitable for use with low bolt loads.

Klinger cold/hot compression
With this test method developed by
Klinger you can evaluate the cold/hot
compression of a gasket in cold and
hot condition.
Unlike the method acc. to DIN
52913 and BS 7531, the surface load
is kept constant during the complete
test so that the gasket is exposed to
much tougher conditions.
The thickness decrease at an
ambient temperature of 23°C and at
heating up to 200°C is measured.
The indicated thickness decrease
at 200°C refers to the thickness
obtained after loading at 23°C.

*Gaskets according to DIN 2690 are
only standardised up to PN 40 and
gasket thickness 2 mm.

The many and varied demands
made on gaskets
The successful operation of a gasket
depends upon a multiplicity of factors.
Many who use static gaskets believe
that the values quoted for maximum
admissible temperature and maximum
operating pressure are inherent
properties or characteristics of
gaskets and gasket materials.

Technical data

Unfortunately, this is not the
case.
The maximum temperatures and
pressures at which gaskets may be
used are influenced by a large
number of factors.
Therefore a definite statement of
these values for gasket material is not
possible.
So why does Klinger provide
pT diagrams?
For the reasons given the pT diagram
is not infallible: it serves as a rough
guide for the end user who often has
only the operating temperatures and
pressures to go on.
Additional stresses such as
greatly fluctuating load may
significantly affect whether a gasket is
suitable for the application.
Resistance to media must be
taken into account in every case.

The fields of decision
If your operating temperatures
and pressures fall within this field,
a technical examination is normally
unnecessary.
.
If your operating temperatures
and pressures are within this field,
a technical examination is
recommended.
If your operating temperatures
and pressures are within this “open“
field, a technical examination is
always necessary.

Important points to be observed
The selection of gaskets requires
expertise and know-how since ever
greater reliability coupled with the
lowest possible leakage rates are
demanded of gasket materials.
The exacting demands made on
the tightness of gasket materials (e.g.
Tightness class L0.01) mean that with
increasing internal pressure higher
surface pressures must be applied to
the gasket.
It must be shown that the flange
joint will tolerate the demands made
on it without being mechanically
overloaded. Furthermore, the surface
pressure applied to create the seal
should never fall below the required
minimum value since this will reduce
the life of the gasket. Highly stressed,
but not overstressed gaskets have a
longer life than understressed
gaskets.
If the gasket fitted will be
subjected to non-static loading, or
will suffer stress fluctuations during

discontinuous operation, it is
advisable to choose a gasket which
is not prone to embrittlement with
increasing temperature (e.g.
KLINGER ®graphite laminate or
KLINGER ®top-chem), especially for
steam and/or water applications.
For discontinuous operations in
water and/or steam applications,
we recommend as a general guide a
surface pressure of about 30 MPa.
In such cases the gasket should be
as thin as is practicable.

Rings and other finished gaskets
These gaskets are available in any size
and corresponding sheet thicknesses.
Function and durability
The performance and life of
KLINGER ®gaskets depend in large
measure on proper storage and fitting,
factors beyond the manufactor’s
control. We can, however, vouch for
the excellent quality of our products.
With this in mind, please also
observe our installation instructions.

For reasons of safety,
we advise against the re-use of
gaskets.
