An 18mm to 14mm downstem features an 18mm joint to connect with the bong’s main body and a 14mm joint to connect with the bowl. This allows compatibility between bongs with an 18mm joint and bowls with a 14mm joint, ensuring a secure and seamless fit.
The 18mm to 14mm downstem is the most common downstem size, with over 90% of bongs on the market using this size. Sometimes, the 18mm to 14mm downstem is also referred to as **18mm by 14mm downstem** or **18mm/14mm downstem**. However, some brands and retailers may reverse these two numbers, but it actually means the same thing.
