JIC-G102288 inch piston seal is designed for hydraulic cylinders in construction machinery, delivering stable sealing, leak prevention, and low-friction performance for reliable replacement in demanding hydraulic systems.
The JIC-G102288 inch piston seal is a high-performance hydraulic cylinder sealing component, featuring a bronze-filled PTFE face ring pre-loaded by a square-section NBR ring. This design provides stable sealing during reciprocating motion, helping reduce leakage risks and improve hydraulic system efficiency.
This piston seal is suitable for replacement in European-brand construction machinery such as CASE, CATERPILLAR, and JOHN DEERE. It can also be used in single-acting applications. With excellent wear resistance, low dynamic friction, and high extrusion resistance, it is ideal for demanding industrial hydraulic environments.
The JIC-G102288 inch piston seal provides a reliable solution for leakage, wear, and pressure fluctuation issues in construction machinery hydraulic cylinders. Its PTFE composite sealing structure reduces friction, improves extrusion resistance, and maintains stable sealing under high-pressure reciprocating motion, helping reduce downtime and improve hydraulic system reliability.
