Not the best for Alembic Dome04/04/2020 ByThomas Draper The diameter of the “screw portion” of the connector is a lot smaller than the diameter of the Alembic Dome. There is too much play/space. On top on that the washer and gasket are JUST big enough to seal if you position it exactly correctly. Although you can make this work for Alembic Dome (why I gave it 3 stars) I would not recommend it to friend for this reason. Going another route with my build now.
