Rod seal nylon backup ring provides essential support to rod seals, preventing extrusion and improving sealing performance. These durable rings reduce leakage, enhance hydraulic system efficiency, and extend component lifespan. Ideal for improving the performance of hydraulic cylinders in heavy machinery.
Rod Seal Nylon Backup Ring is designed to work together with piston rod seals in hydraulic cylinders. It provides essential support to the rod seal, helping prevent extrusion when the system operates under pressure. By improving seal stability, it reduces leakage and supports efficient hydraulic cylinder performance.
This backup ring offers good chemical and wear resistance, helping extend the service life of the main rod seal. It cannot be used alone and must be matched with a piston rod seal. For high-pressure systems, PA material is recommended. Backup rings are available in integral and open/split types for different installation needs.
JSPSEAL provides reliable Rod Seal Nylon Backup Ring solutions for hydraulic cylinder maintenance and repair. By improving extrusion resistance and reducing leakage, these backup rings help extend seal life, lower maintenance costs, and improve equipment reliability. With flexible MOQ, fast delivery, and stable weekly supply, we support heavy machinery repair and industrial sealing needs.
