How to choose the right type and size of a bowl and downstem for your glass bong?


If you are a fan of glass bongs, you know how important it is to have the right accessories to enjoy your herb or tobacco. Two of the most essential parts of any bong are the bowl and the downstem. The bowl is where you pack your material, and the downstem is the tube that connects the bowl to the water chamber. Together, they create the airflow and diffusion that make bongs so smooth and satisfying.

But how do you choose the right type and size of a bowl and downstem for your glass bong? There are many factors to consider, such as compatibility, functionality, aesthetics and personal preference. In this blog post, we will guide you through the basics of bowls and downstems, and give you some tips on how to find the best ones for your bong.

What are bowls and downstems?

A bowl is a small cup-shaped piece that attaches to the top of a downstem or directly to the joint of a bong. Bowls come in different shapes, sizes, colors and designs, but they all have a hole at the bottom that allows the smoke to travel through the downstem. Bowls can be made of glass, metal, ceramic or silicone, and some have features like handles, screens or built-in ash catchers.

A downstem is a long tube of glass that connects the bowl to the bong. The downstem is inserted into the joint of the bong, which can be either male or female. The joint size determines what size of bowl and downstem you need. The most common joint sizes are 10mm, 14mm and 18mm. Downstems also have different lengths, which depend on the height and shape of your bong. Downstems usually have slits or holes at the bottom that create bubbles and diffuse the smoke in the water.

How to measure bowls and downstems?

To measure a bowl, you need to know its joint size and gender. The joint size is the diameter of the opening where the bowl connects to the downstem or the bong. The gender is whether the bowl has a male or female end. A male bowl fits into a female joint, and vice versa. You can use a ruler or a caliper to measure the joint size of your bowl or bong.

To measure a downstem, you need to know its joint size, gender and length. The joint size and gender are the same as for bowls, but you also need to measure how long the downstem is from the top of the ground joint to the bottom of the stem. You can use a ruler or a tape measure to do this, but make sure you measure from the inside of the joint, not from the outside.

How to choose bowls and downstems?

Choosing bowls and downstems depends on several factors, such as:

  • Compatibility: The most important thing is to make sure that your bowl and downstem match the joint size and gender of your bong. For example, if your bong has a 14mm female joint, you need a 14mm male bowl and downstem. If you have different joint sizes or genders, you can use adapters to make them fit.
  • Functionality: You also want to consider how your bowl and downstem affect the performance of your bong. Different types of bowls and downstems can change the airflow, diffusion, flavor and potency of your smoke. For example, some bowls have screens that prevent ash from getting into your bong, while some downstems have more slits or percolators that create more bubbles and smoother hits.
  • Aesthetics: Another factor is how your bowl and downstem look on your bong. You might want to choose bowls and downstems that match or contrast with the color, style and design of your bong. You can also find bowls and downstems that have unique shapes, patterns or themes that suit your personality.
  • Personal preference: Ultimately, choosing bowls and downstems comes down to what you like and what works for you. You might prefer a larger or smaller bowl depending on how much you want to smoke at once, or a longer or shorter downstem depending on how much water you want in your bong. You might also prefer glass over other materials for its durability and purity, or silicone over glass for its flexibility and portability.
