ST-XLFT Wiper Rings
The ST-XLFT was developed for hard environments, particularly longwall mining. These wipers include a dust lip to prevent contaminates from entering through the groove. They also have a ribbed inside diameter for low friction operation and to prevent pressure traps between the wiper and rod seal.
