ZOOK – Graphite Rupture Disks are made from a single piece of graphite which is impregnated in a patented resin. The resulting material called “impervious graphite” is impermeable and is resistant to most corrosives, including alkalis, organic solvents, and most acids.

ZOOK – Graphite Rupture Disks are easy to install and are maintenance free, tamperproof, have no springs or moving arts and mount directly between standard flanges. They are used in chemical, petrochemical, food, medical, and related processing systems around the world.

ZOOK is the first graphite rupture disk manufacturer to earn the ASME Code UD symbol stamp and certificate of authorization. ZOOK has also been certified in accordance with the Pressure Equipment Directive (PED 2014/68/EU) and can provide CE marked graphite rupture disks.
