Style ST wiper rings are precision molded from 90A durometer urethane. Flexible enough to easily snap into a groove yet tough enough to handle difficult rod wiping applications. “V” tagged wipers are constructed of fluorocarbon.

90A Durometer | Urethane Material | 5 3/4 in Nominal Inner Diameter

Features

• Flexible enough to snap into a groove
• Wipers are constructed of fluorocarbon

Wipers are installed in hydraulic cylinders to prevent dirt, dust, and moisture from entering the cylinder as they retract back into the system. A hydraulic wiper prevents contamination that could damage wear rings, seals, and other cylinder components.

90A Durometer | Urethane Material | 6 in Nominal Inner Diameter

Features

• Installed in hydraulic cylinders to prevent dirt, dust, and moistures
• Hydraulic wiper prevents contamination that could damage wear rings, seals, and other cylinder components

Style ST-XL wipers are molded from premium urethane and are direct replacements for Style “ST” or “D” wipers. The outside diameter of the ring has a crush lip providing extra interference in the groove. A bead on the shoulder stops contaminates from entering through the groove. The inside diameter is ribbed to prevent pressure traps between the wiper and rod seal.

94A Durometer | Urethane Material | 5 3/4 in Nominal Inner Diameter

Features

• Crush lip to provide extra interference
• Bead on the shoulder to keep contaminants out
• Ribbed ID to prevent pressure traps

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.

Features

• Include a dust lip to prevent contaminates from entering through the groove
• Ribbed inside diameter for low friction operation
• Prevent pressure traps between the wiper and rod seal
