A Rubber PU Rod Seal is a sealing component designed for use in hydraulic and pneumatic systems, particularly around the piston rod within cylinders. Made from a combination of rubber and polyurethane (PU), this seal is engineered to prevent fluid leaks and protect the internal components of the system by ensuring an airtight and fluid-tight seal. The combination of materials offers enhanced durability, wear resistance, and sealing performance under dynamic conditions.
