FS-V Inverted

ZOOK’s Fluoropolymer Sintered Graphite Rupture Disk (bursting disc) 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 disc).

  • Sizes 1-1/2” (38 mm) thru 10” (254 mm) diameters
  • Burst ratings up to 30 psig (2.07 barg) (Use FS Inverted Type for higher burst ratings)
  • 0% manufacturing range is standard
  • Carbon steel armor standard, 316 optional
  • Furnished complete with set of PTFE gaskets – attached
  • Extended temperature range: –290°F to +500°F (–143°C to +260°C)
