Features

• Double-stepped shoulder

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.

Style AN-M2 scrapers conform to MS28776-M2 sizes and are manufactured in brass. The scrapers are suitable for extreme environments with aggressive contaminants. The unique spring-loaded construction and ductile material result in close rod contact even when coping with rod ovality and helix grinding patterns.

Single-lipped, snap-in rod wiper is designed to fit D-style housings.

The ST-XLF wipers are designed to fit the standard ST wiper groove. 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. Developed specifically for use in harsher environments with heavy contamination, such as in agriculture, off-highway, and forestry equipment.

Urethane Material | 4 1/2 in Nominal Inner Diameter

Features

• Precision trimmed wiping lip
• Retrofits most ‘D’ wiper housings
• Especially effective in vertically mounted cylinders
• Designed to follow the rod deflection caused by side loads
• Interchangeable with Hallite 520 wiper
• Sharp wiping lip scrapes heavy contamination from rod protecting sealing system
• Umbrella Wiper Technology™ protects housing from contamination and reduces moisture ingress

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.
