Mill-Duty, Double-Acting Wiper

Series 317: Mill-Duty, Double-Acting Wiper

The 317 Series Mill-Duty, Double-Acting Wiper is a new design that is water resistant and eliminates internal corrosion associated with other designs. The aggressive profile includes a unique umbrella feature that wraps around the face of the cylinder to create an impenetrable barrier. It works particularly well in vertically mounted cylinders, where contamination collects or fluid splashes on top of the cylinder. The wiper is designed to exclude and protect the hydraulic cylinder in the harshest conditions.



Internal notches prevent pressure trapping

Designed to fit securely in the groove

Long service life

Easy snap-in installation

Available in large diameter up to 2100 mm



The 317 Series Mill-Duty, Double-Acting Wiper is used in severely contaminated, wet and abrasive conditions.

Typical Applications

  • Steel and aluminum processing
  • Cold and hot strip mills
  • Automatic Gauge Control cylinders


The 317 Series Mill-Duty, Double-Acting Wiper features MN76, a high-grade abrasion-resistant elastomer.
