98S32008050000 is a precision aerospace maintenance tool, compliant with AS9100D aerospace quality standards and FAA/EASA regulations, designed for commercial aircraft landing gear systems maintenance.

It functions as a specialized landing gear strut piston seal installation tool, used to install the piston seal into the landing gear strut during MRO work. It applies uniform, controlled force to seat the seal correctly without causing deformation or damage, preventing hydraulic fluid leakage that would reduce the strut's shock absorption performance, cause unstable aircraft taxiing or landing, or lead to structural damage to the landing gear.

Made from high-strength, non-scratching engineering plastic and corrosion-resistant aluminum alloy, it has a dedicated design for specific landing gear strut sizes, and an ergonomic non-slip grip. Weighing 0.78kg, it is portable for on-aircraft or hangar use, critical for landing gear system reliability.
