Wipers

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 | 8 1/4 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

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 | 3 1/2 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

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.

Buna-N Material | 1 1/4 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

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.
