PLAINTIFF'S EXHIBIT Ta: All Salesmen and Frank Dill Lee Taylor Su^a: Change in PERMAF.LEX Gasket April 17, 1968 The 14" and 16" PEPdiAFLEE gasket will be modified per the attached drawing. This gasket has been extensively tested in our laboratory and plant, and it is felt that this design makes a good gasket an even better one. The amount of pressure needed to assemble is no more than the old gasket, and this gasket has even greater stability in the gasket grove. After field experience with 14" and 16", we may wish to modify the other diameter. ILT/rb CAPCO KIN 0000317 .&3Q /<*- ' /6>" GAsner /zsv/s/oss CAPCO KIN 0000318 CEMENT ASBESTOS PRODUCTS CO. RAGLAND.
