The u-ring SNI 07 is produced in a compact design which guarantees good functioning at low pressures. The SNI 07 compact seal additionally has an integrated back-up ring which also prevents gap extrusion at high pressures on the side facing away from the pressure.

U-rings can be installed in both solid and split housings. Please note for a solid housing application a minimum width is necessary and suitable installation tools may be required.

The SNI 07 seal requires relatively small installation housings. Due to the compact fabric back, intrusion into the extrusion gap is prevented.
