Rod seals are the most important seal within any hydraulic sealing system, which are used to prevent leakage of hydraulic fluid to the outside of the sealing system. Rod seals should be paired with an appropriate wiper and gland housing design to ensure correct operation. Rod seals are often the critical factor in ensuring that a hydraulic cylinder operates at peak performance. Leakage through the rod seal can lead to environmental damage and accidents, which is why it’s crucially important to select the correct seal for your application.

JST Seals manufactures rod seals of a comprehensive range of designs including lip seal, cap seal, compact squeeze seal and application–specific designed seal made from high-performance elastomers and engineering plastic materials to offer maximum durability and sealing performance.

Our rod seals can be cured or CNC machined to specified sizes. Plus, we can help to restore the original performance of used equipment, as well as provide components for new build designs. Our standard rod seals can be rapidly manufactured in a variety of different materials, depending on your application. We also stock standard products for immediate shipment if your requirements are particularly time critical. Our engineering team also developed a new process-molding for PTFE rod seal with high performance and less friction. They are hot sale in these years.
