The YNF17348 Lip-Type Seal (OEM reference 150-5697) is engineered for the CAT 306E excavator bucket linkage system. This oil seal ensures reliable grease retention inside the pin joint while blocking external contaminants that commonly cause wear. Made with premium elastomer compounds, it provides long-lasting sealing performance under continuous movement and heavy-load operations.

• Direct replacement for CAT 306E using OEM 150-5697

• Lip-type sealing structure designed for dynamic pin movement

• Strong resistance to abrasion, high temperature, and dirt intrusion

• Helps maintain stable lubrication within the bucket pin joint

• Enhances equipment durability by reducing internal wear

• Flexible rubber formulation suitable for harsh working environments
