A practical addition to a bong: an adapter made from high-quality borosilicate glass. This adapter, approx. 7.6 cm tall, converts a 14.5 mm joint to 18.8 mm, so an existing bong can be combined with a wider range of attachments and accessories.

The adapter is not only practical but also versatile. A special feature is that a screen can be fitted inside it (not included). This way the adapter can be filled with activated carbon, which filters and cools the smoke.
