How to Shop for a Downstem

If you're interested in purchasing a glass downstem, there are some important things to consider prior to purchasing. Make sure you think about the following questions before adding one to your cart:

"What Downstem Size Should I Order?"

Generally, a bong downstem will have a joint size of 14MM, 18MM or even 10MM. The joint size must be a snug fit that keeps an air-tight seal while smoking. However, you should also consider the length of the bong downstem itself. Your downstem should be long enough to hit the water and produce bubbles upon inhalation. If it also hits the base of the bong, this is too long and you won't get the same effects from using the right size.

"Should I Order a Downstem Diffuser?"

A diffuser is optional, but it can attach to your downstem to produce smaller bubbles. These tiny bubbles create smoother draws, so you can enjoy each puff with less harsh results. 

"Can My Water Pipe Use a Downstem?"

If you have a pipe with a male joint, you cannot add a downstem. These will only fit into bongs with female joints.
