Flat face (FF) flanges have a completely flat gasket surface and are commonly used in applications where the flange material is brittle, such as cast iron, or where low-pressure operations are involved. These flanges are suitable for non-metallic gaskets and are particularly effective in water treatment, pump suction flanges, and other low-pressure systems. With various material options available, including stainless steel, mild steel, aluminum, and copper, our flat face flanges offer flexibility in application and competitive pricing. Compared to raised face flanges, flat face flanges are preferred for systems requiring a wider sealing area and reduced torque on bolts.
