Ideal for low-pressure systems and brittle materials (cast iron, PVC), FF flanges feature a flat sealing surface to prevent over-stressing components. Made from stainless steel, carbon steel, or alloys (ASME B16.5/EN 1092-1 compliant), they ensure leak-tight connections in water treatment, HVAC, and general piping. Optional rubber/gasket inserts available for enhanced sealing. Custom drilling patterns and sizes up to DN2000.
