Automotive Connectors For Hotter, Harsher Applications
As emission regulations become more demanding, Vamac® and Viton® are helping automakers hit the mark.
DuPontTM Vamac® and Viton® have been used in automotive hoses and connectors for over 25 years. Today, we are providing higher performance for a new generation of engines and drivetrains that run hotter and use harsher fuels and lubricants.
Chosen for heat and oil resistance, several grades of DuPont™Vamac® ethylene acrylic elastomers are available for specific applications that provide either low oil swell, high viscosity, high or low temperature, and no post-cure or for extrusion.
For emission control components and other underhood applications, Vamac® is used for heat and oil resistance in parts ranging from hoses, dampers and boots to seals and gaskets.
Extreme Heat and Chemical Resistance
Viton® has been the fluoroelastomer of choice for over 50 years. With temperature resistance up to 250°C and resistance to the most aggressive chemicals, Viton® has been used in automotive fuel system components, as well as high-performance parts in the engine and powertrain, for years.
Cost is optimized with high-performance emission hose and connectors when a Viton® veneer is used inside the component made of Vamac®, instead of using Viton® for the entire structure.
