KLINGER
top-graph-2000
Basis
Sealing material, based on graphite
and synthetic fibres. Manufactured
using a revolutionary process which
provides the graphite gaskets with
totally new, previously unachievable
properties.

* Gaskets according to DIN 2690 are only
standardised up to PN 40

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

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 300°C is measured.
The indicated thickness decrease
at 300°C refers to the thickness obtained after loading at 23°C.

Properties
The material impresses with its good
handling in combination with its very
high level of load bearing capacity
and minimal embrittlement at
temperatures up to 300°C. These
properties offer the gasket a high
degree of resistance to damage
during fitting and under operation,
prevents the loss of bolt load and the
formation of cracks at high
temperature. The material is suitable
for use with steam up to 300°C. In
many other areas of application,
temperatures of over 500°C are
possible.
KLINGER ®top-graph-2000
combines the advantages of fibrereinforced gaskets preferred by the
experts with the key features of really
flexible graphite.

The really flexible graphite sealing material
with a high degree of inherent stability offers
reliability in handling. Thanks to its high load
bearing capacity and the low embrittlement,
KLINGER®top-graph-2000 is ideally suited for
use with steam and other sophisticated
applications.

properties or characteristics of
gaskets and gasket materials.
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
fluctuating load may significantly

affect the suitability of a gasket
in the application and must be
considered separately.
Always refer to the chemical
resistance of the gasket to the fluid.
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.

Surfaces
The standard surface finish of the
material is such that the surface has
an extremely low adhesion.

Tests and approvals
BAM approval in accordance with
UVV 28, oxygen (VGB 62) tested up
to 130 bar and 95°C for gaseous
oxygen.
KTW-recommended.
BS 7531 grade X.
DIN-DVGW-permit no.
NG-5123AU0381.
”TA-Luft”-certification (Clean Air Act).

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.
