Aerospace Engine Oil System Seals
General
High-heat and fuel-resistant aircraft engine seals
DuPont materials provide time-tested reliability for aircraft engine, washers and bushings to minimize unscheduled downtime and reduce operating costs.
DuPont™ Vespel® is the material of choice for bushings and washers that must perform in the high-temperature environment of aircraft engines. Components from variable vanes to torque box/bell crank linkage arms can benefit from the wear-resistant, low-friction properties of Vespel®. The key benefits of Vespel® include:
• High performance in environments in excess of 315°C
• Longer component life
• Weight savings over metal
• Lower friction than metal
