The facing on the RF flange has a concentric or a spiral phonographic groove with a controlled surface finish.

Sealing is achieved by compressing a flat, soft, or semi-metallic gasket between mating flanges in contact with the raised face portion of the flange. Flat face (FF) - Typically these flanges are used on pump facings or on fiberglass flanges where the torque of compressing the gasket will damage the flange body.
