Wipers

Style ST-XL-PM wipers are molded from 55D polyester and are direct replacements for Style “ST”, “ST-XL” or “D” wipers. The polyester based material provides a tough abrasion resistant wiper for heavy contaminant environments. 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.

Features

• Molded from 55D polyester
• The outside diameter of the ring has a crush lip providing extra interference in the groove
• The inside diameter is ribbed to prevent pressure traps between the wiper and rod seal

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.

Features

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

A wide range of ST wipers are now offered in the slotted heel design. The slots in the heel allow excess hydraulic fluid to bypass the wiper, preventing wiper blowout.

9 1/2 X 10 1/4 X 3/8 D Wiper

STXE wipers are designed to retrofit the standard ST wiper groove while providing superior performance. The o-ring energizer limits dirt intrusion around the OD of the wiper. The energizer also makes this wiper more effective in applications with severe side deflections.

Urethane Material | 2 in Nominal Inner Diameter

Features

• Designed to retrofit the standard ST wiper groove
• O-ring energizer limits dirt intrusion around the OD of the wiper

Medium Duty Buna Wiper with a crush lip providing interference in the groove helping to eliminate contaminants entering through the groove.

Buna-N Material | 1 in Inner Diameter | Wiper

Each Seal Guard Wiper consists of two flexible bronze rings which are held in place by a nitrile cushion ring. The cushion ring absorbs side loads and energizes the wiper to maintain close contact with the rod. Particularly suited for hostile environments, seal guard wipers shave off sand, grift, slag, flux, paint, moisture, chips and slivers. Seal Guard Wipers are long-lasting, self-adjusting, and offer low friction. Seal Guard Wipers can be installed in standard Hercules® Sealing Products “ST” or “D” Style grooves by increasing the “F” gland dimension to the “F” Throat Diameter shown.

70A Durometer | 660 Bronze; Nitrile Material | 2 1/2 in Nominal Inner Diameter | Wiper

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 | 3 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
