Wipers

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 | 2 in Nominal Inner Diameter

AN wipers are ideal for light duty and pneumatic applications. Its main purpose is to prevent dirt and contaminants from entering the hydraulic or pneumatic systems. Suffix “SH” designates slotted heel design, “V” designates fluorocarbon material, and “B” designates carboxilated nitrile material.

90A Durometer | Urethane Material | 4 1/2 in Nominal Inner Diameter

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 | 2 1/4 in Nominal Inner Diameter

AN wipers are ideal for light duty and pneumatic applications. Its main purpose is to prevent dirt and contaminants from entering the hydraulic or pneumatic systems. Suffix “SH” designates slotted heel design, “V” designates fluorocarbon material, and “B” designates carboxilated nitrile material.

90A Durometer | Urethane Material | 1 3/8 in Nominal Inner Diameter

Utilizing a sturdy metal case, these wipers are molded from the same high performance urethane used in our Heavy Duty U-seals. Built for severe service, these wipers are capable of surviving hostile environments.

92A Durometer | Urethane Material | 1 3/8 in Nominal Inner Diameter

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 | 1 1/8 in Nominal Inner Diameter

Utilizing a sturdy metal case, these wipers are molded from the same high performance urethane used in our Heavy Duty U-seals. Built for severe service, these wipers are capable of surviving hostile environments.

92A Durometer | Urethane Material | 4 1/2 in Nominal Inner Diameter

Molded in nitrile, this wiper features a double lip which prevents fluid that seeps by the rod seal from exiting the cylinder. It features a double-stepped shoulder to fit tightly in the gland throat.

90A Durometer | Nitrile Material | 30 MM 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 | 3/4 in Nominal Inner Diameter | Wiper

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.
