FS-InvertedGraphite Rupture Disk

ZOOK’s Fluoropolymer Sintered Graphite Rupture Disk (bursting disk) offers enhanced features when compared to resin impregnated graphite disks. The Fluoropolymer coating is sintered at a high temperature onto a graphite blank. The durable coating seals the graphite material enhancing the corrosive capability and allows the disk to operate at sub-zero to elevated temperatures with minimal effect on the burst performance of the rupture disk (bursting disk).
