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.
