KLINGERSIL® C-4265

Basis
Mineral Fibres bonded with NBR.
Typical Applications
Suitable for a wide range of applications including oils, solvents and
gases. Excellent conformity with the
flanges at low surface loads.
Max. temperatures 250°C and max.
pressure 40 bar.
(The maximum temperatures and
pressures are dependent on the
thickness of gasket material, flange
conditions, bolt loading and service
conditions. Since the ability of the
gasket material to resist pressure is
dependent on the temperature the
maximum values do not apply simultaneously.)

Gasket for liquids and gaseous media
at lower pressures and temperatures and
low bolt loads.
Good resistance to oils, hydrocarbons,
refrigerants and other chemicals.

Klinger Hot and Cold Compression
Test Method
The Klinger Hot Compression Test
was developed by Klinger as a
method to test the load bearing capabilities of gasket materials under hot
and cold conditions.
In contrast to the BS 7531
and DIN 52913 tests, the Klinger
Compression test maintains a
constant gasket stress throughout the
entire test. This subjects the gasket to

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.
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.

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

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.
