14mm Female to 14mm Male joint glass adapters are very useful for adding a little extra height to your setep.

This can be helpful when using certain glassware such as bottomless bangers with bubblers like the Mega Globe Matrix which doesn't have much room for such things.

• 1 x 14.4mm female to 14.4mm Male Adapter
