The WEH® TSA1 H2 Breakaway coupling offers additional safety for your car fueling station. The breakaway is installed between the dispenser and the filling hose or dispenser and filling/venting hose.

In the event of unexpected tensile forces, e.g. a vehicle driving away with a connected fueling nozzle, the breakaway separates the connections between dispenser and hose(s) in a controlled manner while sealing both ends. Damage to the vehicle‘s receptacle, the fueling nozzle and the dispenser can thus be prevented as far as possible. The breakaway coupling can be reused after a functional test. The integrated filter cleans the hydrogen from dirt ingress and can be cleaned easily and quickly during maintenance.

The WEH® TSA1 H2 Breakaway coupling consists of a coupling body, a receptacle insert and, depending on the version, of a gas recirculation with check valve. A dispenser mounting is available as an accessory. For fueling nozzle with data interface, the TSA1 H2 is also available with a data cable that can be mounted on the mounting.

Refueling kits are also available. They consist of a filling nozzle, hose set, tear-off protection, fuel pump holder, and data cable.
