Hydraulic piston rod wipers in marine hydraulics are essential seals that prevent contaminants like water, dirt, and debris from entering the hydraulic system. They ensure smooth rod retraction and protect internal components from corrosion and wear. These wipers are designed to withstand harsh marine environments, enhancing system longevity and performance.
