Rod Seals

Rod seals are critical dynamic sealing elements primarily used in hydraulic cylinders. They are installed in the cylinder head to seal the reciprocating piston rod, preventing fluid leakage and contaminant ingress. These seals must withstand high pressure, extreme temperatures, and varying sliding speeds while maintaining lubrication. Common designs include single-acting lip seals, double-acting configurations, and sophisticated combination sets that integrate wipers to exclude abrasive particles. Manufactured from durable materials like polyurethane or PTFE composites, they ensure system efficiency, environmental protection, and extended component life. Proper selection and installation are vital for leak-free operation in industrial, mobile, and aerospace applications.
