Hydraulic Piston-Rod Seals

Hydraulic piston-rod seals combine the functions of piston and rod sealing into a single compact design, typically used in double-acting cylinders. These seals prevent fluid transfer between chambers while ensuring that no external leakage occurs along the rod surface. Their dual-function structure provides superior control, longer service life, and reliable performance in medium to high-pressure environments. Manufactured from PU, PTFE, and engineered elastomers, piston-rod seals deliver excellent extrusion resistance and reduced friction. They are widely used in telescopic cylinders, industrial automation systems, mobile hydraulics, and heavy-duty construction machinery. Proper piston-rod sealing ensures higher system efficiency and reduced maintenance costs.
