Rupture discs are widely used in the pharmaceutical, pressure safety, chemical processing, oil and gas, and food and beverage industries, along with original equipment manufacturing (OEM).

Teksal Safety supplies a wide range of high-performance rupture / bursting discs for diverse applications in the oil & gas, mining and industrial sectors.

A rupture / bursting disc is a non-re-closing vent designed to open when exposed to a set pressure differential. The pressure relief device protects processes and equipment from vacuum or over-pressurisation.

Rupture discs can be manufactured from standard materials, including stainless steel, Hastelloy and nickel, as well as non-standard materials such as tantalum, Monel and Inconel.

We source our rupture discs from our global manufacturing partner, OsecoElfab. They focus on developing innovative product technology to maximise performance and fit-for-purpose design. This ensures we deliver the best solution for your application, to achieve optimal performance.

The OsecoElfab rupture / bursting disc range includes:

  • Reverse acting
  • Forward acting
  • Two-way
  • Sanitary
  • Railcar
  • Graphite

Teksal Safety proudly represents OsecoElfab in Australia.


OsecoElfab’s ‘design for manufacture’ approach means we have access to custom solutions for diverse applications and industries.

Common applications we supply overpressure protection for include flare stacks, compressor units, sulphur units, primary treatment units and heat exchangers, fire suppression equipment, gas generators and canisters, separators and distillation columns.

Using OsecoElfab’s innovation resources, we can develop the right technology to maximise your performance capabilities.

Whether you require a standard rupture disc, a complex one-off unit or a high-volume, price-sensitive OEM unit, we work with you to provide the most effective solution.

Technically Advanced

The OsecoElfab rupture disc / bursting disc range includes process discs, plugs and pressure relief assemblies. In addition to those listed below, it manufactures customised products.


  • Oseco Safety Cartridge
    Combines the traditional three components of a rupture disc into one hermetically sealed component for easy installation and to reduce leaks
  • Opti-Gard
    High-performance bursting disc that acts as a single-disc solution to help reduce stock costs
  • Safe-Gard
    Technically advanced rupture disc with cross-scoring for increased safety
  • Double Disc Assembly
    Enhanced environmental protection for processes using harsh chemicals, oil and gas
  • Arma-Gard
    A graphite disc to protect processes using corrosive media and where fragmentation is not an issue
  • Flo-Tel
    Non-invasive, reusable burst detector offers a practical, cost-effective solution for detecting when a rupture disc has functioned


  • Explosion panels
    Range of square, round, flat or domed explosion panels offer rapid venting to protect equipment during deflagrations
  • Electron-beam welded assemblies (OE5 and OE6)
    High-integrity, electron-beam welded disc and plug assemblies, particularly suited to harsh operating environments where superior leak tightness is required
  • PRD
    Designed for clean agent fire suppression systems, the PRD is used for both tank and bottle protection
  • Flo-Tel XD
    Dual-certified Exd/Exia/b, non-invasive and reusable burst detection for use in explosive dust environments, Flo-Tel XD is suitable for use in ATEX Zones 0, 1 and 2


Developed using the latest technology and design, process and manufacturing capability, these products embody the following characteristics:

  • High operational performance
  • Excellent leak tightness
  • Non-fragmenting designs
  • Fast lead-times
  • Two milliseconds reaction time to relieve pressure build-up
  • Cost-effective, maintenance-free designs
  • Electron-beam welding capability for the lowest leakage rate available
  • Flexible supply systems
