Piston Seals

Piston seals prevent fluid leakage between chambers in hydraulic and pneumatic cylinders, maintaining pressure and system performance. Made from durable materials like NBR, HNBR, and PTFE, they resist wear, heat, and pressure. Commonly used in construction equipment, industrial hydraulics, and manufacturing systems for reliable operation.
