Current hydraulic cylinder designs mainly use O-Rings or O-Ring/Back-up Ring combinations as static seals. In applications with pressure pulses or where ingress of dirt is a concern, Dualseal is the preferred solution. The single piece geometry is resistant to twisting during installation and operation and is an ideal solution for automatic assembly processes. High-specification Zurcon® material, combined with an innovative design, extends service life and increases reliability in fluid power applications.
