Rod Koppers are high-performance composite rod seals designed for dynamic sealing in hydraulic cylinder rod applications. The seal construction consists of a low-friction PTFE sealing element supported by an elastomer energiser, ensuring consistent sealing force, reduced friction, and stable performance under high pressure and speed.
This design delivers excellent wear resistance and smooth rod movement, making Rod Koppers suitable for demanding mobile and industrial hydraulic systems where reliability and long service life are critical.
