Why Buy Viton O-Rings?
Viton® O-Ring and seal performance cost benefit makes it the second most popular sealing material. Fluoroelastomer (Viton®, FKM) offers a wide range of resistance to chemicals, oil and heat, with situational service life above 200°C. The outstanding heat stability and excellent resistances are due to the high ratio of fluorine to hydrogen, the strength of the carbon-fluorine bond, and the absence of unsaturation. FKM compounds are widely used in chemical, automotive, aerospace and industrial applications. Fluoroelastomers are referred to generically as FKM polymers per the nomenclature noted in ASTM D1418. In the SAE J200 ASTM D2000 classification system for rubber materials Fluoroelastomers are documented as a “HK”.
Common Viton® Names:
FKM, FPM (Europe), Fluoropolymer, Fluoroelastomer.
Viton® Trade Names:
Viton®, Fluorel®, Technoflon®, Dai-El®.
Specialty Performance Polymer Types:
A, B, F, GLT, GFLT, XLT, ULT, ETP, TBR.
Features Of Viton® O-Rings:
- Situational service life above 200°C
- Excellent resistance to acids, fuels, mineral and vegetable oils and greases, aliphatic, aromatic and chlorinated hydrocarbons, non-flammable hydraulic fluids (HFD) and many organic solvents and chemicals.
- Excellent resistance to aging and ozone.
- Low gas permeability, low compression set.
Limitations of Viton® O-Rings:
- Ketones (MEK,and Acetone) and Skydrol fluids.
- Amines and Anhydrous Ammonia.
- Low molecular weight esters and ethers. Hot hydrofluoric or chlorosulfonic acids and low molecular weight organic acids (formic and acetic acids).
- Polar solvents, low molecular weight organic solvents and glycol-based brake fluids
Viton® Seal Temperature Range*:
-17°F (-27°C) to 437o F (225°C)
Specialty formulations, Low Temperature: -67°F (-55°C)
Specialty formulations, High Temperature: 450°F (232°C)
*Approximation for dry air service. Actual temperature range of a compound in an end-use application is highly dependent on part type, hardware configuration, applied forces, chemical media, pressure and thermal cycling effects, and other factors. Consult a Marco Engineer for more details.
