2 Pcs Glass Tube Adapter 14mm Female to Male 18mm Essential Adapter

The good: Thick and sturdy, no unfinished edges.The bad: doesn't completely seal on my equipment. Very small air leak but gets the job done.

Accidentally ordered a 14 mm collector instead of an 18mm which my piece calls for. Luckily got this the very next day.

Works perfect I've been looking for these since I was a kid its good to see someone finally started making them

Perfect for what I needed. Definitely allows usage of already purchased smaller adapters.

Dont get me wrong. If this glass were any cheaper it would just be sand! But the 5 stars is for the value. It doesn’t have to be made well to serve its purpose.However, just be careful with temperatures! Any rapid changes and pop!

Exactly what I needed, for el bongo. Great if you bought a water pipe and the joint size is too big for the bowl

Wobbles. They fit but wobble, not 100% air tight I don’t think.

Of the two, one is usable. The second is chipped and cracked at top and bottom.
