ARIETE* Fork Seals are manufactured using XNBR* Rubber compound and Stainless Steel metal inserts with Steel tension springs.
XNBR* Carboxylated nitrile rubber is an improved version of NBR* type rubber
It combines the technical properties of nitrile rubber NBR* but with an increased strength, higher abrasion resistance and a tolerance to chemical additives which are used in fork oils.
Seal lips are Fine Ground Finished, which offers complete control of varying internal pressures during extension and compression of the Fork.
