Operating temperature
Teplotní odolnost grafitu je ovlivněna jeho čistotou - čím vyšší čistota, tím nižší oxidace (úbytek materiálu) za vyšších teplot.

Non-standard pressure
Vysekávaná těsnění jsou standardně dimenzovaná pro použití do 40 barů (v závislosti na typu spoje). Pro vyšší tlaky doporučujeme kovová těsnění nebo aplikaci konzultujte.
