311 Series: Dirt Wiper – Double Acting
The 311 Series Double-Acting Snap-In Wiper is a popular upgrade to the tradition single-lip wiper designs.
311 Series
The 311 Series Double-Acting Wiper is a popular upgrade to the traditional single lip wiper designs. It offers enhanced performance and can be easily retrofitted into existing wiper grooves. The double acting design ensures maximum resistance to contamination, while working in tandem with the rod seal to maximize performance. The internal wiping lip is notched to prevent pressure trapping between the wiper and the rod seal. The wiper is designed to exclude and
protect the hydraulic cylinder in the harshest conditions.
