A-EIS-S WIPER SEAL
The Wiper type A-EIS-S is an extension to the A-EIS series, particularly suitable for larger rod diameters.
Firmly adhered contaminants are reliably removed from the piston rod by the A-EIS-S.
The elastic secondary lip prevents even the finest dust from entering the hydraulic cylinder.
