Is the LAUX 42 lever joint gasket, viton, KKG resistant to solvents containing ketones?

No. The LAUX 42 lever joint gasket, viton, KKG is explicitly stated as not suitable for solvents containing ketones. Although it is resistant to mineral oils, gasoline and most chemicals and operates from â30Â°C to +250Â°C, it should not be exposed to ketone-containing solvents.

Can the LAUX 42 lever joint gasket, viton, KKG be used with strong acids or alkalis?

No - the LAUX 42 lever joint gasket, viton, KKG is not recommended for use with strong acids or strong alkalis. The gasket is made of Viton and is resistant to mineral oils, gasoline and most chemicals, but Viton has limited resistance to highly concentrated acids and strong bases. It also is unsuitable for solvents containing ketones. Use chemical compatibility charts or consult the manufacturer for specific media and concentrations before exposure to strong acids/alkalis.

Can the LAUX 42 lever joint gasket, viton, KKG withstand prolonged exposure to gasoline and mineral oils?

Yes. The LAUX 42 lever joint gasket, viton, KKG is formulated from Viton and explicitly described as resistant to mineral oils and gasoline, and to most chemicals. Its operating temperature range (â30 Â°C to +250 Â°C) further supports suitability for prolonged use in typical fuel- and oil-exposed environments. Caveats: avoid contact with solvents containing ketones, as the gasket is not suitable for those. For specific service conditions (concentration, temperature extremes, fuels with additives or biofuels), verify compatibility with the fluid supplier or perform compatibility testing.
