Marine Break-Away

The TODO NGX Marine Break-Away Coupling has been designed to eliminate spillage and damage associated with ship and/or barge movement when loading and unloading hazardous liquids.It also features the market leading flow rate versus pressure drop relationship.

The Marine version of TODO’s tried and tested NGX Break-Away Coupling has been engineered to withstand harsh marine conditions, and as such will only break and separate under a straight-pull force. Forces perpendicular to the line of flow will not affect the NGX Marine Break-Away

The coupler automatically senses an excessive straight-pull load, closes the valves and then allows disconnection.


  • High flow rate / 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 with
