Extensive testing has shown Vespel^® SP-2515 improves the performance of transmission seal rings and attributes that are beneficial more broadly, such as in hydraulic valves, thrust washers and bushings in powertrain applications

Please visit us online at tryvespel.dupont.com to order a sample thrust washer and to see how Vespel® SP-2515 can deliver:

• low coefficient of thermal expansion to better match metal for great leak control in seal rings and protection against vibration and seizure in bearings.;
• excellent wear properties that invite use of light-weight aluminum without costly inserts … and protect mating surfaces from contamination particles to help your component run longer.
• low coefficient of friction for improved efficiency; significantly reduce measured torque loss … more than a 50% improvement versus commonly used seal rings.
• high thermal conductivity to help remove heat from critical surfaces.
