U-ring rod seal A154-090/6 PU 90x98x12 PU92 Alp
A154 U-ring rod nutrings have shorter inner sealing lips and are intended for use in rod applications only in medium duty hydraulic cylinders.
Their second dynamic sealing lip ensures lower oil film thickness and prevents the entry of unfavourable particles into the cylinder.
Material: PU92
