Washers & Bushings for Transportation

High-performance solutions for the toughest sealing, wear or friction challenges

DuPont™ Vespel® polyimides provide time-tested reliability for transportation washers, bushings and seal rings.

Vespel® parts and shapes, both custom and stock, have been tested and proven effective in highly demanding applications around the globe. They are available in sheet, rod, tube, plaque, bar, disk, ring, ball and custom machined parts.

Vespel® is the material of choice for bushings, washers and seal rings that must perform in the extreme conditions of transportation applications. The wear-resistant, low-friction properties of Vespel® provide longer component life and higher performance in environments in excess of 315°C.

Plus, Vespel® makes lighter weight parts not only practical, but in many cases, better than standard metal, ceramics and other engineering polymers such as PEEK (polyether ether ketone) and PAI (polyamide-imide).

With design centers in Asia, Europe and the Americas, DuPont technicians collaborate with customers to combine materials science with design to produce high-performance parts and keep production running smoothly.
