About Stub-in Branches
A stub-in branch is distinguished from a branch fitting because the stub-in branch does not contain any solid fitting part. The pipe solid parts of a stub-in branch intersect and are trimmed. The stub-in branch is either equal to or smaller in diameter than the main pipe, and can be created at an angle to the main pipeline, or offset from the top or bottom of the main pipe solid part.
