Adapters for Bongs – Connecting Joint Sizes
Adapters are the small problem-solvers of your setup. They connect different joint sizes and make accessories compatible that wouldn't normally fit together. Whether you want to use an NS-14.5 bowl on an NS-18.8 bong or connect a vaporizer to your glass – with the right adapter, it's possible. We manufacture our adapters from thick-walled borosilicate glass with precisely fitting joints.
Why do you need an adapter?
- Connect joint sizes – e.g., NS 14.5 to NS 18.8, so your accessories fit.
- Connect a vaporizer – with a glass adapter, you direct the vapor through your bong.
- Integrate activated carbon – activated carbon adapters provide additional filtration and cool the hit.
How to find the right adapter
Two values are crucial: What joint size does your bong (or downstem) have, and what joint size does the part you want to connect have? An adapter bridges precisely these two. Also, pay attention to the direction – they exist depending on whether you want to go from small to large or vice versa. If you're unsure, just tell us what you want to connect.
Frequently asked questions about adapters
What is a bong adapter good for?
It connects two different joint sizes so that accessories fit that wouldn't otherwise go together – for example, an NS-14.5 bowl on an NS-18.8 bong.
What joint sizes are there?
The common ones are NS 14.5 and NS 18.8. An adapter usually bridges precisely these two.
Can I connect my vaporizer to the bong?
Yes – with a suitable glass water filter adapter, you direct the vapor through the water of your bong. This cools and softens the hit.
What is an activated carbon adapter?
An adapter with an integrated activated carbon function that filters out some of the harmful substances and additionally cools the hit.
What material are your adapters made of?
From thick-walled borosilicate glass, handmade with precisely fitting, precision-ground joints – so everything fits snugly.
