25213-61 ABSTRACT OF THE DISCLOSURE A method for preventing fluoroelastomer-related hydroly- sis of a gas stream comprised of a fluorine-containing substance, which gas stream is contained in an industrial system provided with at least one fluoroelastomeric article, includes the step of providing at least one fluoroelastomeric article comprised of a fluoroelastomer and lead oxide, the lead oxide content correspond- ing to a lead percentage in the fluoroelastomer ranging from 1 to 10 percent by weight. The fluoroelastomeric article may be a seal for the industrial system. Further, the fluorine-containing sub- stance may be selected from the group consisting of UF6, HF, BF3, SiF4, MoF6, WF6, halogen fluorides and mixtures thereof.
