The GF7700 packing has the words 100% GORE® GFO® on it to guarantee its authenticity.
The special technique used to encapsulate the graphite inside the ePTFE matrix is still something that differentiates it from other types of graphite-filled PTFE.
The perfect and homogeneous graphite distribution increases its heat distribution capacity when the seal is in service.
Together with the high toughness of ePTFE, this characteristic allows GF7700 GORE® GFO® to maintain excellent levels of performance.
