What Is a Bong Downstem?

A downstem is a long tube of glass. It works as a connecting point, pulling together the body of the bong and the bowl with the product inside. When a person inhales, the smoke goes through the stem and permits the individual to take a hit.

There are many types of downstems. Some are fixed to the piece, meaning they cannot be removed. Others are detachable, allowing easier cleaning and swapping out of pieces users might not want.

There are also diffused downstem options packed with a diffuser. This item aerates the smoke and permits a smoother hit for the individual. Downstems are a vital part of the smoking experience.

Now that you know what one is, are they necessary for your experience? Do you need a stem to put your bong to work?

Do You Need a Downstem for a Bong?

Although a downstem isn’t the most exciting tool, it’s necessary for a water pipe. It’s a critical connection point between the mouthpiece and the bowl. Without it, there is no way for the smoke to drift upwards into the mouth portion for the best experience.

They also filter and aerate the smoke, working to create smooth hits for the user. They are necessary for purification and filtration processes, often overlooked by even the most experienced users.

Now that you’re hunting for a bong stem, what is the standard size for this product? What should you be looking for in a store if you want one everyone else invests in for their bong?

What Is a Standard Size?

There are many different sizes. You can purchase tiny versions or buy something longer for a quality experience. What is the standard size for downstems on the market today?

The most common size downstem is 14mm. This size is ideal for typical users, providing enough room to filter and aerate the smoke before it reaches the mouth of the user. Most options on the market are about 14mm, and that’s a safe place to start if you aren’t sure what to purchase for your product.

If you use a stemless bong, the standard size is different. It sits at 14mm to 18mm, a little longer to create the optimal experience. Consider these lengths if your bong does not have a stem.

No matter what size you use, you are sure to have an excellent experience. Now, let’s consider—what size do you need?

What Size Do You Need?

The size you select will depend on your preferences and the type of bong you own. Some pipes will only fit some sizes, while others permit more flexibility.

Measure your stem and bong to determine the proper size. We will review the measurement process for a downstem next to help if you need to replace one you already own.

How Do You Measure a Bong Stem?

It’s vital to have proper measurements if you are interested in a new downstem. However, some may struggle with understanding how to measure them. What’s the ideal measurement procedure for this tool?

If you want to measure your stem, you should:

  • Remove the bong stem.
  • Locate a measuring tool.
  • Measure the product from the tip to the end of the joint ground.
  • Note the measurement

This measurement will come in handy when it comes time to replace the downstem in your system. It’s vital to understand the ideal length for your bong.

Now that you know all about length, what are these stems made of? What are your options?

What Are Downstems Made Of?

What are downstems made of to create the best possible experience? They must withstand exposure to high temperatures and smoke over extended periods. Thanks to these requirements, they must be made of specific materials to ensure they remain in one piece.

There are two materials most downstems are made of:

  • Glass
  • Silicone

These allow for the best experience, ensuring the product does not melt or fall apart when heat is applied.

Let’s dive deeper into these materials to ensure you know the available options. It’s up to you to determine whether glass or silicone downstems are better for your needs.


Glass downstems are one of the most popular selections. The glass is typically borosilicate glass, a type made to withstand exposure to high temperatures.

A glass stem piece is an excellent choice if you want to invest a little more into your downstem and want an elegant appearance. Glass options are classy and effective.

It’s critical to note that glass is higher-end and breaks much easier than its counterparts. Care for them well to keep them in tip-top shape.

The other option is silicone, which will allow room for more creativity and customization. Let’s talk about this variety next.


If you want pink downstems or any colored options, silicone material is ideal. This product is colorful and flexible, permitting unique customization and use from the owner. They are much more affordable than their glass counterparts, and you will get a lot of use from them.

Although there are options for colored glass, they are much higher-end than the silicone version. Those who want affordability, portability, and a quality look will enjoy the silicone downstem.

Once you have your downstem, it’s time to swap out the stem on your current pipe. How do you complete this process?

How Do You Change a Bong Downstem?

When you have a bong, it’s critical to invest in a replacement every once in a while, to keep the system in optimum shape. If you’re interested in the best upkeep of your pipe, how often should you change it? When should you purchase a new downstream for your system, and how do you change it?

There is no set time for the lifespan of these stems, but each product should have an estimated lifespan on the packaging. It’s usually clear when it’s time to change your piece. It will be old, worn, and dirty.

Once you invest in a new stem, here’s how you can change the product in your system:

  • Gently lubricate the area where the stem attaches.
  • Pull it out
  • Take the new one out of its packaging.
  • Replace the old one with your new selection.

Everything will be good as new after this switch.

Ensure you test the system as soon as you make the switch to determine if it’s in working order. If it doesn’t work, you may need to make a tiny adjustment to put the stem in the ideal position.

Now, you know how to change one. How much can you expect to pay for one if you’re hunting for one on the market?

If you’re interested in this product, you might wonder—how much is a downstem? How much will it take from your pocket to invest in a quality version of this tool?

These stems vary in price. You will find some ranging from affordable to higher-end. Here are a few sample products and the price you will pay for each selection:

It’s up to you to determine which is the best product for your preferences.
