Maximum Safety During CNG Refueling
Unexpected situations can easily arise during everyday CNG refueling – for example, when a vehicle drives off with the fueling nozzle still connected. Such tension loads often result in damage to the dispenser, fueling nozzle, or vehicle receptacle. This is exactly where WEH® CNG Breakaway Couplings come into play: they automatically and safely disconnect the connection, instantly seal both line ends, and prevent costly repairs. Whether for passenger cars, fleet vehicles, or commercial trucks – a suitable solution is available for every application.
Low Maintenance & Ready for Use – Even After Disconnection
The well-engineered design of WEH® Breakaway Couplings allows for easy integration into existing CNG systems. Many models can be reused immediately after a functional check – without costly factory refurbishment. This saves time and minimizes downtime. Optionally integrated filters clean the natural gas during refueling, protecting the fueling nozzle and vehicle components from particles and deposits. Ideal for fueling stations that prioritize maximum availability and low maintenance.
