Practical tip

ST-FF is interchangeable within the ISO16028. Please note that ST-FF is not designed to connect against residual pressure. However if you can't avoid residual pressure in your hydraulic circuit please refer to our Seriess ST-3FF.

Benefits

ST-FF has been tested with 1.000.000 impulses and exceeds the market standard in wear resistance and working pressure.
