Face Type-FF Full Face
FF-Full Face equal in JIS Standard structurally equal to Flat Face in ASTM standard. The Flat Face flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.
