Due to having a higher density, Viton has the widest temperature range of -40°F to over 400°F (-40°C to over 240°C) making it a perfect choice for higher temperature applications. Viton® also has the largest range of chemical resistance, i.e., it is resistant to silicone oil and grease, mineral/vegetable oil and grease, aliphatic, aromatic, and chlorinated hydrocarbons, non-flammable hydraulic fuels as well methanol fuels, and more.

The key advantage of silicone oil seals lies in their resilience and durability. Silicone, as a material, is known for its ability to maintain flexibility over a broad temperature range, from -100°C to 200°C. This makes it ideal for applications where extreme temperatures are common, such as in automotive, aerospace, and chemical processing industries. The oil component further enhances the seal's lubricating properties, reducing friction and wear on mating surfaces.
