Case 1346359C1 SPG piston seal is designed for reliable hydraulic cylinder sealing in heavy-duty construction machinery. Its composite sealing structure helps maintain stable pressure, reduce leakage risk, and support smooth piston movement in demanding working environments.
JIC-1346359C1 SPG piston seal is a hydraulic sealing component designed for inch-size piston applications. It combines a bronze-filled PTFE face ring with a square-section NBR energizer, helping provide reliable sealing performance, low friction, and stable operation in demanding hydraulic cylinder systems.
This piston seal is suitable for construction machinery replacement and maintenance applications. It helps prevent internal leakage, supports pressure retention, and maintains smooth piston movement under continuous working conditions. Its durable material combination makes it a practical choice for heavy-duty hydraulic equipment.
JIC-1346359C1 SPG piston seal provides an effective solution for hydraulic cylinders with leakage, pressure loss, or unstable piston movement. By combining a low-friction PTFE sealing surface with an elastic NBR preload ring, it helps improve sealing reliability, reduce wear, and extend maintenance intervals in construction machinery hydraulic systems.
