What Is an 18mm to 14mm Downstem?
An 18mm to 14mm downstem (also written as 18/14mm downstem, 18mm by 14mm downstem or 18mm 14mm downstem) features a 18mm male joint that fits into your bong, while the other end holds a 14mm female joint for your bowl. This type of downstem is often used to reduce joint size so you can use a smaller bowl or accessory with a larger water pipe.
