Wipers

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.

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.

• Ribbed ID to prevent pressure traps

The Hallite 820 single-lipped, snap-in rod wiper is designed to fit North American D-style housings and has been developed specifically for use in harsher environments with heavy contamination, such as in agriculture, off-highway, and forestry equipment. 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.

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.
