- High flow rate and low pressure drop
- Durable breakaway marine construction and reliable after prolonged use
- Designed to resist axial forces found at sea
- Operates independently of shut-off safety systems
- No external power source required
- Easy to reset on site
The TODO NGX Marine Breakaway coupling is engineered as a high‑safety break-away coupling specifically for marine and offshore environments. It is designed to eliminate spillages and prevent damage to equipment aboard ships during loading and unloading of hazardous liquids. The durable breakaway marine construction ensures safe disconnection when excessive straight‑pull load is applied.
Like TODO’s standard NGX Break-Away coupling, the Marine version offers market‑leading flow rate and low pressure drop for efficient transfer operations. Its design withstands tidal motion, vessel movement and the demanding conditions found in offshore transfer.
Ranges & Variants
The NGX BreakAway Marine comes in 2-4” sizes and is shipped with 3mm pins as standard. However, it can be configured according to a customer’s specific needs. See the table below for a full list of possible end connections and O-ring grades.
