Determining whether the joint size for the bowl slide on your bong is 14mm or 18mm can sometimes be tricky. For a lot of smoking products online the joint size of a bong is typically in the product listing. There are times however, when that is not always the case. Furthermore, it is not uncommon for companies to remove products listings since glass pipes and bongs are ever changing with new designs and colors coming out constantly. For that reason, it is always good to be able to tell for yourself whether the joint size on your bong is 14mm or 18mm. To do this is incredibly easy and all you need is a dime!
The pictures below show a simple and effective way to tell if your bong joint size is 14mm or 18mm. For 14mm bong joints, the dime will not fit in the joint at all. If you stand the dime upright, only a small portion on the bottom of it will sink into the bong. On the other hand, for 18mm the dime can actually fit inside the joint slot. If you stand it upright and put it in the joint slot the dime almost disappears. It is literally as easy as that to figure out the joint size of your bong!
You may be asking how you can tell the joint size from the bowl slide of the bong also. Well do not worry, we got you covered! If your bong down stem breaks and you need to figure out the joint size of your bong from the bowl, you can still do it easily with a dime. Like the method above, this is also very simple. You can tell from the bowl slide whether your bong joint size is 14mm or 18mm by how much area of the dime each size covers up. For an 18mm bowl, if you set the bowl on top of a dime the bowl will barely fit and you will only be able to see the edges of the dime. For a 14mm bowl slide, when you place it on top of a dime you can clearly see a lot more of the dime. The pictures below show the difference in coverage.
If you are still confused on the joint size of your bong, do not worry, you are not alone! Determining the joint size of your bong can take time to figure out. If you ever have questions about the joint size of your bong, we recommend contacting the retailer you purchased it from as they usually have that information readily available.
