The YNF17151 PU-C307 Seal (246×267×15) is a heavy-duty hydraulic oil seal designed for large-diameter shafts and housings in construction and industrial machinery. Made from high-performance polyurethane (PU) material, this seal offers excellent wear resistance, high load capacity, and superior sealing performance under harsh operating conditions. It effectively prevents oil leakage while resisting abrasion and deformation, making it ideal for hydraulic cylinders, gear cases, and large rotating or reciprocating components.
