Flexible graphite, due to it's softness
seals great but can also break if bent too far. To make it easier to handle
we offer it with a 316 S.S. foil insert, tanged insert, or for easier cutting
- no insert at all. Available in a range of grades from automotive &
Industrial to Nuclear. |

In many applications when oxygen
is present and the temperature is over 850 F the ideal sealing material
Grafoil® flexible graphite cannot be used. Flexible graphite
or Flexible Graphite will coke at those elevated temperatures when oxygen
is present. An excellent alternative in many applications is Mica.
Some of the basics on Mica are shown below. As a gasket
material Mica can be very effective in sealing those high temp critical
applications with out failing due to the presence of oxygen. For

Die formed sets for valves in applications that require the lowest of leak rates. Now a standard in the valve industry because of it's effectiveness, Carbon yarn end rings with die formed flexible graphite center rings |
 |
Thermabraid Temp: 1200 F Steam, 0-14 pH A high temp packing good for most applications. Now available in this braided version that eliminates the need for dies. Great for high temp or chemical applications (non-oxidizing) that can not leak. When you have to have the leak rate near that of a Mechanical Seal in a pump this is the packing to use.
