A40 Wiper
A40
Wiper with a sharply-defined lip edge made from NBR 90. The A40 is a single function wiper. It is pressed against the descending piston rod wiping the dirt from the surface of the rod. The seals, their associated elements and the medium are protected from the dirt. Pads on the inner diameter support the correct functional fit by preventing additional pressure build-up in the back area which could press the wiper out of its housing.
