4 Reasons Why the Medical Industry Uses Viton O-Rings for Sealing Applications

08 August 2022

O-rings, also known as gaskets or washers, are mechanical sealing components that can remove the gap between two or more mating surfaces. The primary purpose of these components is to prevent leaks among objects while they are being utilised.

Many materials can be used in manufacturing O-gaskets. These materials include nitrile, neoprene, and ethylene propylene. Nitrile is often picked due to its resistance to silicone greases, hydraulic fluids, water, alcohols, and petroleum-based oils and fuels. Neoprene, alternatively, has moderate resistance to weather, a low compression set, and good resilience. Ethylene propylene, ultimately, has excellent resistance to water, steam, heat, alkali, ozone, mild acidic and oxygenated solvents, and sunlight.

While these materials can truly benefit many industries, one O-ring material that works well with medical sealing applications is Viton. Viton O-rings, which are made from fluorocarbon compounds, are being utilised by the medical industry due to the following reasons.

Exceptional Chemical Resistance

One of the reasons Viton O-rings are being maximised by the medical industry is they have superb chemical resistance. Many applications in the medical industry revolve around harsh chemicals, gases, and solutions, which can be damaging to many materials. Fortunately, Viton O-rings have excellent resistance to oils, acids, silicone fluids, glucose, oxygen, and carbon dioxide. Their capability to withstand the effects of these elements makes them perfect for sealing various medical equipment and tools.

Reliable Temperature Resistance

Another reason Viton O-rings are utilised by many medical businesses is they have reliable resistance to high temperatures. Viton itself can easily withstand temperatures ranging from -25 to 230 degrees Celsius without compromising its shape, flexibility, and mechanical properties. So, once used as the O-ring material, the medical industry can effectively attain and maximise dependable sealing materials during their high-temperature operations. Their resistance to extreme temperatures likewise makes them long-lasting and valuable.

Great Resistance to Compression

The resistance quality of Viton O-rings does not end with chemicals and temperatures. Medical sealing applications can also benefit from these gaskets since they can remain strong even under pressure and compression. Other gasket types like rubber tend to become brittle in the long run, especially if they are being utilised in applications that are always under pressure. Viton O-rings, alternatively, can resist compression regardless of the environment, preventing them from getting brittle or obtaining cracks.

Compliant with Industry Standards

One more reason why Viton O-rings are preferred by the medical industry for their sealing applications is they comply with industry standards. As long as they are generated by reliable manufacturers, Viton O-rings are expected to meet the strict sanitary standards of the regulatory authority. Some provisions of the standards include the manufacture of the gaskets in a cleanroom. They must also be quality tested and packaged properly to prevent contamination. With high-quality Viton O-rings, the industry can carry out its applications easily.

Viton O-rings can be effective in sealing leaks, valves, pumps, and other similar medical-grade tools and elements. To obtain these gaskets, you can contact us at Gasketech. We are a supplier of gaskets and sealing washers, extrusions, and mouldings for all industries.
