It's hard to get a fillet of glue on the inside edge of a coupler assembly.
Apply a ring of glue on the inside edge of the coupler. Try to apply it a smoothly as possible. The glue will want to bead up, that's okay.
Then apply a second ring of glue on the outside edge.
Set the adapter ring on the glued edge of the coupler.
While the glue is still wet, TURN the adapter ring against the edge of the coupler.
This will smooth out the glue bead on the inside edge and give you a (fairly) smooth internal fillet.
Repeat for the other side.
Let dry sitting on the flat ring so the glue won't run.
It hurts to sit on the ring.
