The SNI 39 u-ring is a single-acting rod seal with an asymmetrical design. A second seal lip supports the sealing function of the SNI 39 u-ring. Due to the synergy of the geometry and material, this design is exceptionally well-suited for extreme loads.

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 tool may be required.

Seals made of TPU are very robust and are particularly well-suited for applications in mobile hydraulics and especially in the area of earth moving machines.
