In the world of industrial sealing, material quality can make the difference between a reliable, long-lasting system and one prone to breakdowns, leaks, and costly downtime. As industries demand higher operating temperatures, more aggressive chemicals, and improved efficiency, gasket materials must meet increasingly rigorous performance standards. This is why Viton® gaskets, known for their exceptional durability and chemical resistance, have become a preferred choice across demanding applications. At Midwest Gaskets, we specialize in manufacturing precision-engineered Viton gaskets that meet these modern challenges with reliability you can trust.

What Is Viton?

Viton is a family of fluoroelastomer (FKM) rubber materials originally developed by DuPont (now Chemours). Unlike standard elastomers, Viton features a fluorinated molecular structure, which gives it unique characteristics not found in common gasket materials such as nitrile (NBR), silicone, or EPDM. This specialized composition provides exceptional resistance to heat, chemicals, fuels, and environmental exposure — making Viton one of the most robust materials available for sealing applications.

Key Performance Advantages of Viton Gaskets

Because of its superior material properties, Viton stands out as a premium choice for applications where failure is simply not an option. Midwest Gaskets utilizes high-grade Viton compounds to ensure every gasket delivers reliable, consistent performance. Some of the most important advantages include:

1. Exceptional Chemical Resistance

Viton is specifically designed to withstand a wide range of harsh chemicals that quickly degrade traditional gasket materials. It performs especially well when exposed to:

• Fuels — including gasoline, diesel, and aviation fuels

• Engine oils, hydraulic oils, and other lubricants

• Solvents and aromatic hydrocarbons

• Many industrial chemicals used in processing and manufacturing

This comprehensive chemical compatibility allows Viton gaskets to maintain their integrity in environments where standard rubber materials soften, swell, or break down. For facilities handling fuel mixtures, aggressive solvents, or chemically reactive compounds, Viton is often the only material capable of providing long-term sealing stability.

2. High Temperature Resistance

Industrial processes increasingly push temperature limits to improve efficiency and performance. Viton gaskets are engineered to withstand continuous temperatures up to 200°C (392°F), with certain grades tolerating short-term spikes up to 250°C (482°F). This far exceeds the capabilities of many traditional elastomers, which begin to fail or deform at significantly lower temperatures.

Because of this temperature resilience, Midwest Gaskets’ Viton components are widely used in:

• Automotive and aerospace systems

• High-temperature chemical processing

• Oil and gas production

• Power generation equipment

• Industrial machinery and manufacturing lines

When elevated temperatures are a constant factor, Viton provides the reliability needed to maintain a tight, long-lasting seal.

3. Low Compression Set and Long-Term Stability

A gasket’s ability to maintain shape and sealing force over time — known as compression set resistance — directly affects system longevity. Viton excels in this area, retaining elasticity and sealing power even after prolonged exposure to heat and pressure.

This reduces the likelihood of leaks, minimizes maintenance demands, and allows systems to operate for longer intervals between gasket replacements. For industries where downtime is expensive or disruptive, this durability is a critical advantage.

4. Resistance to Weathering and Environmental Degradation

Viton’s fluorinated structure also provides excellent resistance to external environmental stressors such as:

• Ozone

• UV radiation

• Oxidation

• Outdoor weather conditions

This stability makes Viton gaskets ideal for long-term outdoor use, as well as applications involving exposure to atmospheric contaminants or changing environmental conditions. Unlike many elastomers, Viton will not crack, harden, or degrade prematurely when exposed to sunlight or harsh atmospheric environments.

5. Ideal for Demanding and Specialized Applications

Thanks to its combination of heat resistance, chemical durability, and long-term flexibility, Viton is used in some of the most demanding industries, including:

• Automotive and aerospace: Fuel system seals, engine components, and high-temperature connections

• Chemical processing: Pumps, flanges, mixers, and tank seals exposed to aggressive chemicals

• Oil & gas: High-pressure systems, refinery equipment, and fuel transport lines

• Pharmaceutical and food processing: Systems requiring consistent, contamination-free sealing

• Vacuum systems: Due to Viton’s low gas permeability and heat stability

Wherever conditions are extreme — whether in temperature, pressure, or chemical exposure — Viton remains one of the most trusted materials available.
