Viton™ Fluoroelastomers for Automotive

High Performance Starts with the Smallest Components

Automakers are reducing the size of powertrains, engines, and engine compartments to cut fuel consumption, in addition to using advanced air management systems to improve fuel efficiency and to adopting new types of materials to meet the needs of electric vehicle components. These changes bring elevated temperatures and exposure to corrosive fluids and fumes, shortening the life and, in some cases, even destroying elastomer parts.

Hoses, seals, gaskets, high-voltage cables and O-rings made with Viton™ fluoroelastomers stay flexible and elastic in higher temperatures significantly longer than products made from other rubbers. When exposed to synthetic lubricants and harsh chemicals, including fuel and powertrain fluids, parts made with Viton™ fluoroelastomers maintain their properties and outperform products that are made with other fluoroelastomer materials (also called FKM).

That’s why automotive engineers specify the use of Viton™ fluoroelastomers in:

Air management systems

  • Air-intake manifold gaskets
  • Turbocharger hoses
  • Vent hoses

Fuel systems

  • Fuel hoses and seals
  • Fuel injector O-rings

Oil and grease

  • Axles

Electric vehicle systems

  • High-voltage power cables

Durability Is in Demand

Modern cars need longer lasting components. Improvements in engine design and onboard technology, combined with higher quality oils, are extending the time between service calls for most cars today. With longer gaps between scheduled visits, there are less inspections by mechanics—resulting in fewer opportunities to replace worn or damaged parts.

This is also true in electric vehicles, where the battery, motor and related electronics tend to require even less scheduled maintenance than their conventional counterparts.

Changes to car designs are placing more components in hard-to-reach or sealed areas, which means replacing a part that degrades or malfunctions can be time-consuming and expensive, both for the manufacturer and vehicle owner.

The growth of car-sharing services increases the potential for breakdown, as many vehicles are now operating consistently for several hours a day.

These fundamental changes in how automobiles are manufactured and used mean hoses, seals, gaskets, and O-rings must last longer, without being inspected or maintained. Components made using Viton™ fluoroelastomers have extended life due to their exceptional durability, superior quality, and core properties, including:

  • Ability to maintain strength and flexibility over time in extreme operating temperatures
  • Chemical resistance to fuels, exhaust, and other fumes
  • Permeation resistance to reduce the impact of evaporative emissions
