FKM X-rings show great resistance to most chemicals, mineral oils, greases, fuels, ozone and aromatic hydrocarbons have great strength to FKM X-rings though
Viton or FKM X-rings offer more strength than any of the other elastomers to a wider spectrum of chemicals coupled with very good high temperature characteristics.
The quad rings of FKM we offer are the closest approach accessible to an universal elastomer for sealing in comparison with all other elastomers in use for fabrication of X-rings and other custom seals.
The small gas permeability of fluorocarbons makes them well suited for hard vacuum service and many formulations are self-extinguishing.
Hot water, steam, polar solvents, small molecular weight esters and ethers, glycol-based brake liquids, or warm hydrofluoric or chlorosulfonic acids are usually not recommended for use with FKM X-rings. They are are not consistent with organic acids and brake liquids especially when their molecular weight is low.
