Fabricated out of pipes, the ASME B16.9 Type C Stub End is a fitting that could be used both with lap joint and slip-on backing flanges. The lap of C-type stub ends is flared over, while the lap thickness is 75% that of the connecting pipe WT. Type C stub ends have a short fillet outer radius, which has the ability to host any backup flange.
