Stub Ends

Stub Ends are fittings used in place of welded where rotating back up are desired. They are also called Lap Joints and Vanstone Flared Laps. A rotating back up seats itself against the back surface of the Stub End. When bolts are added, the clamping action of the bolts presses the rotating back up against the back of the Stub End.

When bolts are added, the clamping action of the bolts presses the rotating back up flange against the back of the Stub End. The surface of the Stub End then presses against a and another surface providing joints like standard flange joints. The seal is made by the surface of the stub end alone, the flange only provides the clamping pressure on the joint.
