Qualities that Make Viton “A” Ideal for Automotive Gasketing24 July 2018
The best synthetic gasketing materials have plenty of company. They’re originally manufactured as single-solution rubbers and plastics, but then the chemist gets into a fine-tuning “groove.” Before long, different variants are keeping the original product company. And so it is with Viton “A,” a fluoropolymer-based synthetic elastomer. A core member of the main Viton product group, this synthetic rubber seems like it’s found a match-made-in-heaven relationship with the automotive industry.
Resists Lubricant Attack
Oily streams course all throughout a car’s internal combustion engine. Viton “A” is the go-to gasketing product here because the material incorporates a potent lubricant resistance feature. Attacked by the many oils and greases that are carried in automobile conduits, the gaskets won’t deteriorate when they’re in contact with these potentially aggressive fluids.
A Hydrocarbon Hero
Next up, the petrol, gasoline for our American cousins, used to fuel cars is based on a complex soup of combustible hydrocarbons. Like the lubricants in the engine, that fuel was created when it was processed in some faraway oil refinery. At any rate, hydrocarbons are known for their gasket-abusing aptitudes. Well, thanks to a set of qualities that clearly targets these refined fluids, Viton “A” gaskets tolerate hydrocarbons very well. Imagine a lesser rubber seal in there, one that was deteriorating because of the fuels solvent-like features. Fuel leaks cannot be allowed, which is why this fluoropolymer-based synthetic is seen as the de facto solution in car fuel systems.
Enduring the Combustion Cycle
A mistreated car issues a bang and pulls off to the side of the road. Another car is suffering, too. It’s still running, but a strangely coloured smoke trail is pouring from the exhaust pipe. Everyone knows great internal energies are being consumed everytime a car engine starts. As the car ages or gets prematurely aged by a speed-enthusiast, its gaskets become brittle. Happily, Viton “A” is a robust elastomeric product. It withstands the high temperatures and pressure differentials that spike when engines are pushed to their limits. Frankly, the gaskets in the cylinder heads and engine block should never be perceived as a machine weak link, and A-type Viton exists to reinforce that mandate.
Emissions regulations are now incredibly stringent in the automotive sector. Furthermore, there are many, many fuel variants coursing below petrol station islands. They have special additives and exotic engine cleaners. Even if a tough gasket was specifically designed to contain regular petrol streams, there’s no way the same could be said when these exotic mixes are used. Well, thanks again to Viton “A,” whatever the fuel or oil formulation, a fluoroelastomer-gasketed vehicle will continue performing at its best, with no leaks.
