For engine applications that require durable, long-lasting performance, DuPont™ Vespel® parts provide high dimensional stability and perform well even in poorly lubricated or dry environments with high PV limits.
Vespel®, with its ability to operate continuously at high temperatures with low friction and low wear, is an exceptional material for engine components, including:
• Crank shaft thrust washers
• Timing belt tensioner bushings
• V V T (variable valve timing) seal rings
• Timing chain guides
Plus, Vespel® offers excellent resistance to engine oils.
