Always verify compatibility using the machine model, serial number, and OEM part number before ordering, as sealing washers can vary in internal diameter, external diameter, thickness, and sealing material between machine models and production revisions.

IMPORTANT INFORMATION

Always confirm the correct OEM part number, machine model, serial number, and assembly specification before ordering, as sealing washers are manufactured to precise dimensions and sealing requirements. Installing the correct component is essential to prevent fluid leaks, maintain system pressure, and ensure reliable machine operation.

Common signs that a sealing washer requires replacement include fluid leaks around the joint, compression set, cracking, hardening, deformation, or damage caused during removal. When replacing the sealing washer, it is recommended to inspect the associated bolt or fitting, sealing surfaces, threads, and surrounding components for signs of wear or damage. Replacing any worn associated components at the same time will help maximise the reliability and service life of the complete assembly.
