Sakagami GPY- Piston Packings made from high-grade NBR (RN919) are engineered for superior durability, wear resistance, and long service life. Designed for hydraulic and pneumatic cylinders, these packings provide excellent sealing performance even under demanding pressure and temperature conditions. Their increased cross-sectional design compared to SKY-Packings ensures greater stability, protection from extrusion, and extended operational efficiency. With optional standard or high-pressure back-up rings, GPY Packings can handle higher pressures while preventing backflow damage, making them ideal for industrial machinery, heavy equipment, manufacturing automation, and hydraulic systems.
