O-Ring, Kalrez® 4079, Size #009

O-RINGS, KALREZ® 4079

Kalrez® 4079 perfluroelastomer combines the elastomeric properties of Viton with the chemical resistance of PTFE, making it the best possible o-ring material available. Kalrez® 4079 should be considered for service in high temperature, corrosive environments such as:

· Polar Solvents such as Ketones, Esters and Ethers
· Strong Organic Solvents such as Tetrahydrofuran, Bensene, Dimethylformamide and Perchloroethylene
· Acids such as Hydrochloric, Nitric and Sulfuric
· Strong Oxidizing Agents such as Dinitrogen Tetroxide and Fuming Nitric Acid
· Metal Halogen Compounds such as Titanium Tetrachloride and Diethylaluminum Chloride
· Hot Mercury and Caustic Soda
· Chlorine-Wet and Dry
· Inorganic Salt Solutions
· Fuels such as JP-5, Aviation gas and Kerosene

Kalrez® 4079 exhibits exceptional thermal stability and is serviceable at long-term temperatures to 316°C and intermittent temperatures to 343°C. Kalrez® 4079 is not recommended for use in sealing applications below -5°C. For complete chemical resistance and fluid compatibility, see chart in the front of this catalog.
