FSGGRG - Graphite Rupture Discs

The FSGGRG Graphite Rupture Discs are replaceable and designed for mounting on either graphite holders (rated for pressures up to 10 bar g) or metal holders (up to 15 bar g). These highly versatile discs cater to a wide range of applications and are particularly efficient in handling aggressive fluids while exhibiting low sensitivity to temperature variations at bursting pressures. Constructed from ultra-pure graphite, the discs are impregnated with phenolic resins, which enhance their impermeability. When ruptured, they provide a complete opening while fragmenting into manageable pieces. For rupture pressures below 1.7 barg, vacuum support is necessary; however, these discs are self-supporting at higher pressure calibrations.
