O-rings and seals are critical components of any fluid system. They play a significant role in preventing leaks, equipment failure, and safety hazards in industrial processes of all sizes and scopes. Choosing a suitable o-ring/seal material for your operation’s processes is a crucial choice, helping to extend equipment life, reduce unexpected downtime, and eliminate hazards for your equipment and workers.
Since 1977, Hy-Lok has been a leading Canadian manufacturer and distributor of industrial fluid system components, offering one of the most expansive inventories in North America. Today, we’re proud to add Viton seals as an option for our range of check valves. Read on to learn more about Viton’s properties and uses cases, as well as Hy-Lok’s complete selection of check and relief valves.
Viton: Properties and Applications
Viton (also known as FKM by ASTM International standards and FPM by ISO 1629) is a fluorocarbon-based elastomer initially developed by DuPont. Like many fluorocarbon elastomers, Viton has an exceptionally large operating temperature range (-46ºC to 230ºC, depending on material grade), combined with an ability to resist a wide variety of chemicals and fluids, including:
- Mineral oils and greases
- Aromatic and chlorinated hydrocarbons
- Gasoline and diesel fuels
- Silicone oils and greases
- High-vacuum operating environments
Thanks to its wide operating temperature range, chemical compatibility, high density, and excellent resilience and durability, Viton has become an industry-standard seal in many applications, including:
- Chemical processes and petroleum refining
- Semiconductor manufacturing
- Food & pharmaceutical
- Analysis & Process Instruments
