Stub End

A stub end is mainly used with flanges in a piping system for allowing quick disconnection of the particular section involved. This metal fitting is generally installed in pairs and linked together with two lap joint flanges. Using our lap joint stub ends allows sections of the pipeline to be opened for cleaning, inspection, quick replacement and other operations without having to re-weld.
