This style is one of the premier gasketing materials available today. In addition to the excellent chemical and heat resistance normally associated with flexible graphite materials, Style 344-3 has the greatest crush resistance of almost any non-metallic gasketing material. This translates into uses at extreme temperatures and pressures.
