Original Hansen series ST

Original Hansen coupling with straight-through design

Original Hansen Rohr-Schlauch-Schnellkupplung – Serie ST

Straight-through hydraulic and pharmaceutical coupling

The ST coupling series is characterized by its extremely robust design. It is particularly eligible for applications where the flow must be guaranteed even with highly viscous media such as greases and a shut-off can be dispensed with.
