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.

Features

• Crush lip to provide extra interference
• Bead on the shoulder to keep contaminants out
• Ribbed ID to prevent pressure traps

Asymmetric rod seal designed with precision trimmed sealing lips to provide a dry sealing solution in light and medium-duty applications.

The Hallite 605 is molded in Hythane® 181, Hallite’s high-performance polyurethane, for easy installation and excellent low temperature performance.

Designed to have interference in the seal housing groove and has a secondary lip. The secondary sealing lip located behind the primary sealing lip improves stability of the seal in the gland.

The inner dynamic lip is shorter and more robust to improve sealing and compression set characteristics over conventional, symmetrical U-seals.

The seal can be considered for use in heavy-duty applications when used with a suitable full depth back-up ring. The sealing lips are precision trimmed at an angle to give optimal rod sealing performance.

• General purpose rod seal
• Robust design
• Excellent wear resistance
• Increase seal stability
• Performs well over wide temperature range and is extremely effective in low temperatures
• Primary lip protection
• Easy to install

Wear rings provide a hard-wearing surface that protects the cylinder walls and the piston rod from scoring and abrasion. By maintaining alignment and reducing side loads, these rings facilitate smoother piston movement and lower friction levels.
