Kaxite cork and nitrile rubber sheet is a blend of high-quality cork granules and nitrile rubber (NBR) binder, engineered for high resistance to oils, aromatic fuels and solvents. It is the grade specified when a gasket joint will see petroleum-based media. The H-series is supplied in eight standard thicknesses from 1/32" to 1/2" and five standard sheet sizes from 12"×12" up to 36"×36". Each grade can be certified to meet Grades A, B or C of MIL C 6183 B Class 1. The cork component preserves compressibility and recovery, giving reliable sealing under thermal cycling and repeated bolt-load relaxation. Custom thicknesses and sheet sizes are available on request.
