When to Choose Viton
Choose Viton when you need both chemical resistance and high-temperature performance in one gasket — it outperforms Buna-N on heat and chemical breadth. It costs more than standard elastomers, so reserve it for demanding chemical or high-heat service.
Viton Gasket FAQs
What is Viton gasket material?
Viton is a fluoroelastomer (FKM) with outstanding resistance to fuels, oils, acids, and aggressive chemicals at high temperatures — a premium material for demanding sealing.
How does Viton compare to Buna-N?
Viton handles higher temperatures and a much broader range of chemicals than Buna-N, but costs more. Choose Viton for heat and chemical breadth, Buna-N for economical oil sealing.
What chemicals does Viton resist?
Viton resists most fuels, oils, acids, and solvents. Its main weaknesses are ketones, hot water/steam, and low-temperature flexibility.
