Composite gasket material formulated with mineral fibers, organic fibers, and inorganic fillers, bonded with an NBR binder system.
Versatile general-purpose grade ideal for low-pressure applications involving steam, water, oils, fuels, and inert gases in low-stress operating conditions.
Suitable – Material is typically compatible when chemical resistance requirements are met
Conditionally Suitable – Potential suitability exists but requires technical validation prior to use
Not Recommended – Strict technical evaluation mandatory before installation
