Know your joint/connector size
The most common bong joint sizes are 10mm, 14mm and 18mm female connections. Smaller bongs tend to use 10mm or 14mm joints and the larger ones tend to use 18mm ones, but this isn’t always the case. Some larger bongs still utilize 14mm joints and vice versa.
A quick, easy and cost-effective to utilise your existing burners or vapes is a low-profile glass adapter that allows you to use a 10mm male joint in a 14mm female joint or a 14mm male joint in an 18mm female joint:
Some dab rigs have the less common 10mm, 14mm or 18mm male connections. You can use an adapter that accommodates both male and female joints:
Fortunately, most water pipe adapters have a tapered design which makes them compatible with the more common joint sizes. Always make sure your bong maintains an airtight seal with your device for optimal performance
