The N25 u-ring has a symmetrical design which allows it to be used both as a piston seal or a rod seal.
The N25 can be installed in cut grooves starting from an inner diameter of 25 mm with the use of suitable installation tools. With smaller diameters or larger profile widths, we recommend axially accessible installation housings.
Seals made of TPU are very robust and are particularly well-suited for applications in mobile hydraulics, particularly earth moving equipment.
