A153 U-ring rod nutrings, that have shorter inner sealing lips, are produced for only rod applications.

They leave lower oil film thickness due to the their second dynamic sealing lip. At the same time, they prevent the entry of unfavourable particles into the cylinder.

POM back up rings offer high resistance to extrusion.
