Lap Joint Flange

Description: The lap joint flange is practically identical to a slip-on except that it has a radius at the intersection of the bore and flange face. This radius is necessary to have the flange accommodate a lap joint stub end, The stub end is mated with the lap joint flange and used together in piping systems. There are many uses for this type of assembly, from saving costs to creating joint systems.
