1 SSTTRREESSSSSSTTRREESSSSThe new Flexitallic LSI spiral wound gasket reflects over 80years experience in high-performance static sealing technolo-gy. This dynamic leadership is is backed up by ISO certifica-tion, comprehensive engineering support and knowledgeablecustomer service, in short, Total Quality other company knows more about spiral wound gaskets , infact, Flexitallic invented the spiral wound gasket. Now we vetaken this technology to a higher BOLT STRESS -REDUCED FUGITIVE EMISSIONSF lexitallic recommended minimum bolt torque figuresfor use with the LSI gasket on flanges.*NPS (IN.)
