When you compress a Viton seal, it can conform to the shape it is compressed into even after it's removed. Viton and nitrile are the two elastomers most used for building O-rings, but Viton works especially well in high-temperature applications. . Viton Seal Temperature Range*:-17F (-27C) to 437o F (225C) Specialty formulations, Low Temperature: -67F (-55C) - 59 to 120. Low gas permeability, low compression set. Viton O-rings have an extremely wide temperature range -50C to +205/230C (-15F to +400/440F) Low compression set and low gas permeability Order Viton O-Rings from the worlds largest Viton O-Rings inventory network. In fact, one Viton o-ring can withstand temperature ranges from -13F to 446F. Some formulations are generally compatible with hydrocarbons, but incompatible with ketones such as acetone and methyl ethyl ketone, ester solvents such as ethyl acetate, amines, and organic acids such as acetic acid. Why O-ring Shelf Life Matters for Industrial Seals. Full operation at 450F will shorten parts lifetime more than full operation at -15F. Gas permeability is very low and similar to that of butyl rubber. There are many advantages to using an o-ring for your sealing needs, including their ability to hold a strong seal through a wide range of temperatures. Benefits. aromatic and also special chlorinated hydrocarbons. Below is a breakdown of these two categories and how the main o-ring material types stack up: As previously mentioned, o-rings provide a wide range of temperature variance where they will still provide a seal. The temperature range for a specific compound may not reach these maximum limits. Fluorocarbon (FKM) compounds combine high-temperature resistance with excellent chemical resistance. News With intense versatility and resistance properties, Viton is typically the right material choice for more heavy-duty applications. All of the designations stand for one single base material, which is fluoro rubber. Viton fluoroelastomers withstand extreme automotive underhood conditions. and Aromatic Hydrocarbon Process Fluid Chemicals. [2] It is commonly called fluorine rubber or fluoro-rubber. Subscribe me your email newsletter. . FKM, FPM (Europe), Fluoropolymer, Fluoroelastomer. Viton F-605C* fluoroelastomer is a new generation incorporated cure "F-family" terpolymer designed for compression and transfer molding of seals, gaskets, and O-rings that require excellent fluids resistance to today's automotive fuels. When a project or situation needs sealing, the vast majority of the time an o-ring does the trick. Consult a Marco Engineer for more details.

Download Viton 75 Information in PDF SPECIFICATIONS MET FKM is an abbreviation of Fluorine Kautschuk Material. The temperature ranges presented above are approximations for dry air service only and should not be used to determine design specifications or end-use temperature limits. Perfluoroelastomers (FFKM) are an extension of the Fluorocarbon FKM elastomers extending the compatibilities of the FKM while at the same time extending the upper temperature limits of the materials while compromising the lower temp limits. The low strength and poor abrasion resistance as well as high gas permeability, make them not compatible with the most petroleum fluids, ketones, water, and steam. This is a critical stage in development, as every rubber compound carries its own strengths, weaknesses and sealing capabilities.
Viton O-Rings | Global O-Ring and Seal Fluorocarbon elastomers are highly fluorinated carbon-based polymers used in applications to resist harsh chemical and ozone attack. Also known as Boss O-rings, these hard Viton fluoroelastomer O-rings are for use in tube fittings with a straight-thread connection. Temperature Range:-260F to 300F. Vito, Dai-El and Technoflon are brands for FMP polymers. A detailed list of fluids/chemicals with their compatibility ratings for use with the most common O-Ring materials. Worlds largest O-ring inventory network. Viton is a specific brand of Fluorocarbon (FKM) and is a registered trademark of The Chemours Company. 30. This popular o-ring material family comparison shows basic rubber material family properties and performance plastic properties. Amines (Ammonia)
For others type 60 to 90 Shore A are appropriate. See Popular Compounds list below for compound examples.

Ketones (MEK,and Acetone) and Skydrol fluids. The most practical way of determining an end-use temperature range is testing in the actual application conditions. Additionally, temperature highs and lows are often given in terms of prolonged functional abilities, which may raise the minimum or reduce the maximum this is important to remember, as your o-rings will not be used once or twice in quick bursts but will be counted on for extended time periods under these heat conditions. AED resistant, Norsok M710 and NACE T0297 tested Wide chemical resistance including H2S and Oxygenated fuels. While Viton is resistant to a long list of chemicals, it is not recommended for exposure to: In contrast with its high-temperature resistance, Viton does not retain flexibility at low temperatures, so it is not recommended for low-temperature applications.
