Within a hydraulic cylinder, immense force is generated to perform critical work—from lifting heavy loads to precise industrial automation. At the core of this force generation is a component that must be perfectly sealed: the piston. Piston seals are the unsung heroes responsible for containing this power, directly influencing the force, speed, and efficiency of your entire hydraulic system.

PEEK backup rings are widely used in ultra-high-pressure sealing fields with harsh working conditions. In petroleum and natural gas drilling equipment, they adapt to ultra-high pressure and high-temperature downhole working environments, protecting drilling tool sealing systems from medium erosion and pressure extrusion.

O-rings are the most widely used elastomeric sealing components in hydraulic, pneumatic, and industrial fluid systems due to their simple structure, low cost, and reliable static and dynamic sealing performance.
