Graphite Rupture Disks, the resulting material called “impervious graphite” is impermeable and is resistant to most corrosives, including alkalis, organic solvents, and most acids.

ZOOK is the first and largest company in the world committed to manufacturing quality impervious graphite rupture disks, through product innovations and superior service. ZOOK is the first graphite rupture disk manufacturer to earn the ASME Code UD symbol stamp and certificate of authorization. ZOOK is certified in accordance with the Pressure Equipment Directive (PED 2014/68/EU) and can provide CE marked graphite rupture disks. ZOOK has been certified to AS9100D:2016 (ISO9001:2015), meaning that our Quality Management System at our graphite manufacturing facility has been certified to the Aviation, Aerospace and Defense industry compliance standards. The AS9100 Standard includes the ISO9001 standard as its foundation, but is much more stringent in its requirements.

ZOOK graphite rupture disks protect capital equipment and personnel from the effects of overpressurization in static and dynamic pressurized systems. The disk is designed to rupture at a predetermined burst rating when installed. Each disk is made from a single piece of graphite, a high-purity form of carbon, which is resin impregnated. The  resulting material, called impervious graphite, is impermeable and is resistant to most corrosives.

Our graphite rupture disks:

• Are easy to install and maintenance-free
• Are tamperproof
• Have no springs or moving parts
• Mount directly between standard flanges 

Options and accessories are also available to increase the flexibility of standard graphite disks. Mounting sensors, special gaskets and stainless steel armor are also available. Spacer rings let you replace metal rupture disks without requiring piping modification.
