Rod Seals prevent the leakage of fluid from within a hydraulic cylinder to the outside as the rod cycles back and forth (dynamic pressure sealing). Rod seals work together with wiper seals to protect a hydraulic system against external contaminants such as dirt and outside weather conditions.
Rod seals are static seals installed in the glands or housings. They maintain a seal with the piston rod in dynamic motion.
In heavier duty applications, a rod seal can be combined with a secondary buffer seal for a more robust sealing effect.
