ShanghaiProduct Description
HRX Metric Hydraulic Rod Seal is a high performance rod seal designed for hydraulic cylinders operating under demanding conditions. Combining a wear-resistant polyurethane sealing element with a reinforced backup ring, it delivers reliable sealing performance, effective pressure relief, and enhanced protection for the primary sealing system.
Its specially engineered outer lip features pressure-relief grooves that efficiently release trapped back pressure, helping prevent damage to the main rod seal. With excellent wear resistance, impact resistance, and anti-extrusion capability, this PU rod seal for hydraulic cylinder applications is ideal for heavy-duty equipment, including excavator cylinder rod seal systems, where durability and long-term reliability are essential.
