Is the LAUX 42 Lever Joint Gasket, Viton, KKG compatible with solvents containing ketones?

No — the LAUX 42 Lever Joint Gasket, Viton, KKG is not compatible with solvents containing ketones. The product description explicitly states it is not suitable for ketone-containing solvents.

Can the LAUX 42 Lever Joint Gasket, Viton, KKG be used with steam or in high-humidity industrial environments?

The LAUX 42 Lever Joint Gasket, Viton, KKG offers excellent chemical and temperature resistance (–30°C to +250°C) and is well suited to many harsh industrial environments. Viton displays good resistance to steam at moderate temperatures and high humidity, so the gasket can be used in many steam-exposed or humid applications. However, prolonged exposure to saturated steam at high temperature or continuous condensate may accelerate ageing compared with dry service, and Viton is not compatible with ketone-containing solvents. For critical steam applications (especially saturated steam above ~150–200°C, continuous high-pressure steam, or where sterilization cycles are involved), validate compatibility with actual service conditions or consult LAUX technical support to confirm long-term suitability.
