| SPECIAL RECOMMENDATIONS |
|---|
| Special Recommendations | There are many other grades of Viton with modified properties; e.g. GLT for extra-low temperature (-40°C), VTR-4590 for high fluid resistance. Also, gasket manufacturers have their own designations. · All Viton formulations tested so far pass ECSS-Q-70-02 and have an Oxygen Index similar to that cited above. |
