IUIY type buffer seal is a high-performance hydraulic buffer ring specially designed for hydraulic cylinder piston rod assemblies. It is installed in front of the main rod seal to absorb sudden pressure spikes and impact loads during reciprocating operation. By releasing transient peak pressure, the IUIY buffer seal effectively protects the primary rod seal from shock damage and greatly extends the service life of the whole sealing system.
Manufactured from premium polyurethane material, IUIY buffer seal has excellent impact resistance, wear resistance and stable mechanical properties. Its optimized cross-section profile delivers outstanding anti-extrusion performance under cyclic high pressure, resisting deformation and extrusion failure under repeated shock conditions. It can operate stably at peak pressure up to 40 MPa, with working temperature ranging from -30℃ to 100℃.
Compatible with mineral hydraulic oil and most conventional hydraulic fluids, IUIY hydraulic buffer seals are widely applied in excavators, loaders, injection molding machines and other heavy industrial hydraulic equipment. It fits standard seal groove dimensions for quick installation and direct replacement. With reliable pressure buffering capability and low maintenance cost, the IUIY buffer seal offers an ideal shock absorbing sealing solution for heavy-duty hydraulic systems.
