Rod seals play a vital role in protecting a hydraulic system from contamination. These small but mighty pressure barriers stop fluid from escaping from a hydraulic cylinder while preventing dirt and other contaminants from entering the system too. They may seem like just a small part, but rod seals help to prevent costly and disruptive problems which can lead to poor performance, system failure and safety issues. Rod seals can be found in all hydraulic or pneumatic equipment, including highways tools and excavation and mining equipment.

Also known as gland seals or neck seals, rod seals are installed within the glands, or head, of a hydraulic cylinder. They function as a pressure barrier to regulate the operating fluid when a cylinder is in a dynamic motion. They seal the pressure from one side (a single acting rod seal) or both sides (double acting rod seal). To work at their best, rod seals are usually paired with a wiper, which also helps to prevent contaminants from entering the hydraulic system.

Rod seals come in a huge array of sizes to allow them to fit a range of hydraulic cylinders. You can also choose from a variety of materials, including rubber, plastic, polyurethane and elastomers. The choice of material usually depends on the temperature at which it will be expected to operate, the pressure and the working environment.

If a system leak does occur, the rod seal could be a potential cause and they may need replacing regularly to ensure the best performance.
