AFM 34

AFM 34 is an asbestos free gasket material. It consists of aramide fibers, inorganic fillers and asbestos substitutes that are resistant to high temperatures. These are firmly bonded to high grade elastomers under elevated pressure and temperature to achieve exceptionally high gas sealability.

Service

For DIN and ANSI flanged joints, apparatus, pumps, fittings and pipelines in industrial plants
For fittings with very narrow sealing surfaces, e.g. in gas and hot water units, solarpanels, convection radiators and
couplings, etc.
For sealed joints in IC engines subject to high mechanical and thermal stress (oil filters, intake manifolds, water, fuel
& vacuum pumps, etc.)
For transmissions, gearboxes, refrigerating & air compressors, etc.
Since AFM 34 is physiologically safe, it is also suitable for use in contact with drinking water & foodstuffs, and for sealing highly
pure, pollutant- sensitive products such as paint bases, vitamins, etc.
