Technical Data Sheet 126 (previously TDS 122)
Edition: 08/2015, supersedes all prior editions.
Please see the latest issue at www.reinz-industrial.com |
|
Material
|
AFM 26 consists of a tanged and galvanized steel core. An
asbestos-free soft material compound
containing aramide fibers, inorganic fillers and high-grade binder elastomers is applied to both sides of the core.
|
Properties
|
In spite of the metal reinforcement that gives the material the required mechanical
strength plus good stress resistance, AFM 26 exhibits
excellent compressibility and recovery. Consequently, AFM 26 conforms very well to
sealing surfaces, and compensates even major surface irregularities.
The
moderately priced material is resistant to oils and fuels, etc. It is also
suitable for sealing hot water and steam up to approx. 200 °C in stationary
applications and with an installation surface pressure of at least 50 N/mm². In such
cases, AFM 26 outperforms conventional fiber gaskets.
Compared with graphite gaskets, the material is easy
to assemble and handle. Please consult us if you have a specific application.
|
Application
|
- for sealed joints that are subjected to high mechanical stress, e.g. intake
manifolds, cast iron oil pans, valve covers, transmission flanges and
high-pressure pumps
- for irregular sealing faces and/or lightweight components with low pressure and
relatively high thermal stress
- for sealing hot water and steam in pipeline flanges up to outer diameters of
500 mm.
|
Surfaces
|
For special applications, full-surface or partial coatings are available, e.g. a non-stick coating on a PTFE basis (also
possible on materials in roll form) or a silicone-based coating that
improves micro-sealing (only available as a finished gasket). Screen printing
with various elastomers is also possible.

The data quoted above are valid for the material "as delivered" without
any additional treatment. In view of the countless possible
installation and operating conditions, definitive conclusions cannot be
drawn for all applications regarding the behaviour in a sealed joint.
Therefore, we do not give any warranty for technical data, as they do
not represent assured characteristics. If you have any doubt, please
