18mm Female to 18mm Male glass adapters are especially useful for extending your setups when there isn't space to fit a bubbler on otherwise. They are particularly useful with setups like the HydroBrick Maxx by Sticky Brick as they allow hydrotubes like the Swiss Tree or Matrix Hydrotube to be mounted on top without blocking the storage pot hole.
