Fike GD Series or Graphite Rupture Disc


Made from phenolic resin-impregnated graphite, Fike Graphite rupture discs offer excellent corrosion resistance.

GD Series

  • No holders (mounts between companion flanges) for easy installation.
  • Easily customizable to the customer’s exact specifications.
  • For GD Discs in vacuum service (GDV), a vacuum support will be required if the burst pressure is less than 20 psig.
  • GDI SERIES (inverted) rupture discs typically are supplied in higher burst ratings and are produced for Class 150, Class 300 and equivalent flange ratings.
  • GDL SERIES rupture discs extend corrosion resistance to highly oxidizing agents, halogens and virtually all other corrosives (except free fluorine), and are suitable for specified temperatures up to 430°F without insulation.
  • GDHT, GDIHT, GDLHT SERIES Insulated discs accommodate specified temperatures up to 700°F. They utilize fibrous silica and alumina, which is not suitable with liquid applications, and can be attacked by hydrofluoric and phosphoric acids and concentrated alkalis.

How Rupture Discs Work

A rupture disc is a non-closing pressure relief device used to protect industrial applications from overpressure- or vacuum-related events. Learn about how rupture discs work and what sets Fike apart in its rupture disc manufacturing process.
