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 Size Downstem 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.

Downstems are a crucial part of most bongs. Although some bongs have an attached downstem, most models need a seperate downstem in order to function. The downstem is the part of the bong through which you pull the smoke into the bong water. Unfortunately, bong downstems sometimes break when cleaning a bong, when it falls off your kitchen counter or table. Bongify is your one-stop shop for replacement downstems, and best of all: they’re cheap!

Here you can find all bong downstems in our assortment. This includes glass downstems, metal downstems, diffuser downstems, cheap downstems and “inside cut” downstem adapters. We also offer “chillums” which are essentially a downstem and bowl in one piece.

What is a downstem?

A bong downstem, also known as a “downpipe”, “chillum” or “adapter”, is the little pipe in your bong through which the smoke is drawn into the bong and through the water. The downstem is a seperate component that fits into the bong. A bong bowl is mounted on top of the downstem. The herbs in the bowl are lit and the smoke is drawn through the downstem. A bong downstem is therefore not only essential, but it can also improve your smoking experience. A good downstem has a good airflow with enough space for the smoke to pass, fits into your bong perfectly and is made of strong and durable glass (borosilicate glass or “scientific glass” downstems). For drastically improved smoking comfort you should use a diffuser downstem.
