Know your joint/connector size
Once you’ve found a water pipe attachment for your vape, you’ll need a bong that’s compatible with it. The most common bong joint sizes are 14 mm and 18 mm female connections. Smaller bongs tend to use 14 mm joints, and the larger ones tend to use 18 mm ones, but this isn’t always going to be the case. Some larger bongs still utilize 14 mm joints and vice versa.
Other bongs, mostly old-school dab rigs, might have the less common 14 or 18 mm male connection. Stay away from those, unless you have an adapter that accommodates both male and female joints, or if you don’t mind using an additional female-to-male adapter.
Choose bigger bongs
Larger bongs tend to be heavier than the smaller ones. In addition to being more stable, there are other benefits to using a bong with some size to it. If your bong is too small, it’s not going to have a huge impact on your vape sessions. From my experience, the larger percolator-style bongs tend to work better because they provide more noticeable bubbling action. Smaller bongs are more portable, but if you want the full experience, then bigger is always going to be better. Besides, who walks around with a bong in their bag all day anyway?
Another tip to consider when buying a bong is the angle at which the adapter sits. A lot of bongs tend to have the downstem sitting at an angle, which is not ideal, especially for portables. Bongs meant for dabbing tend to be stemless, so that’s one less glass part to worry about.
Don’t overfill your bongs
Fill your bongs with water before attaching it to your vape. Inhale through the mouthpiece, and if any excess water comes up, then pour some out and repeat. If there is too much water in the bong, it could get into the adapter or the vape itself. This could potentially ruin your flower or, even worse, your device.
