Piping (T-Junction)
A three-way pipe junction.
It is one of the four shapes that take part in over-pressure failure, so the weakest plain pipe on a run, whether or not it is this junction, sets the burst rating for the whole thing.
A wrench cycles only the orientations valid in its cell; where the neighbours already decide it, there is nothing to cycle and it will not turn.
