Function
The SNI 73 u-ring is produced in a compact design which guarantees good functioning at low pressures and guarantees a particularly long service life. The SNI 73 is a single-acting rod seal. The second seal lip strengthens the sealing function and the semi-active back-up ring on the inner diameter prevents gap extrusion on the side facing away from the pressure.
