Stainless Steel Stub End

We are manufacturer of stainless steel stub end and supplies A403 304,316,317 in place of welded flanges where rotating back up flanges are desired.

Feature

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