Jianuo Scientic Glass Tube Adapter, 18MM Female to 14MM Male Essential Adapter

Do not buy this 14mm male to 18mm female adapter. It didn't even last one session before it broke. Save your money

Shipped broken.Update*** new one delivered but the quality of this glass is still garbage. I am not happy. There must not be quality control at the factory.

Fits but the bulbous mid section cracks easy. It seems to be consistent throughout other reviews as well.

Works like intended to adapt my larger bowl to the smaller stem

Perfect glass piece now I can add all the extra pieces to my bong 😋😋I had to order it again I broke it after a few months of use still a great piece

Broke in half after 2 uses. Waste of money.

Fits as advertised, nice solid piece...

I received it quickly and was exactly what it was supposed to be
