Hitachi seal kits offer durable and reliable sealing solutions for heavy equipment. These high-quality seals prevent leaks, reduce downtime, and improve the performance of hydraulic systems. Ideal for maintaining and enhancing the efficiency of Hitachi machinery in demanding environments.
Piston Back Up Ring is designed to provide essential support for piston seals in hydraulic cylinders. It helps prevent seal extrusion under pressure, reduces leakage, and improves the overall sealing efficiency of hydraulic systems. This makes it a practical component for maintaining stable piston operation in demanding equipment.
With excellent chemical and abrasion resistance, the back up ring enhances the extrusion resistance of the main seal and extends its service life. It is widely used in hydraulic cylinders, industrial machinery, and heavy equipment where durable sealing support and reliable performance are required.
JSPSEAL provides reliable Piston Back Up Ring solutions for hydraulic cylinder maintenance and repair. By improving seal extrusion resistance and reducing leakage, these rings help extend seal life, lower maintenance frequency, and improve hydraulic system efficiency. We support flexible MOQ, fast small-order delivery, and stable weekly supply for customer requirements.
