TODO NGXM Marine Breakaway Couplings, ATEX Approved


The TODO Marine Break-Away Coupling has been designed for loading and unloading hazardous liquids on ships and/or barges. The Marine version of TODO’s tried and tested Standard Break-Away Coupling has a more robust design and has been engineered to withstand harsh marine conditions. If excessive load is detected, the coupler closes the valves and then allows disconnection.

The TODO NGXM Series Break-Away again takes the principles of the engineered NGX Series and makes the product suitable for offshore applications. The addition of five load pins protects the break pins against lateral forces (i.e. tidal and wave movement), resulting in a high performance Break-Away that will only separate due to an overload in straight pull force.


  • High flow/low pressure drop
  • Designed to resist axial force so that disconnect only occurs
  • when subjected to straight pull forces
  • Operates independently of shut-off safety systems and does not require an external power source
  • Easy to re-set on site


  • Faster loading/unloading due to the optimised flow rates offered
  • Simple to retrofit onto Loading Arms
  • Easier to handle when loading/unloading
  • Reduced maintenance due to internal redesign and new seal placement
  • Easy to reset on-site, saving time, saving money
