What Features Make It A Better Choice?
Beyond its basic function, this downstem set includes smart design touches that solve common problems with standard bong parts.
How Does The Adjustable Length Work?
The downstem is made of several threaded parts. You screw them together to get the length you need, from a short 3-inch setup to a long 6-inch one. This design removes the guesswork of measuring and makes sure you have the right size, even for a new bong.
What Is It Made Of?
It's machined from a solid piece of aircraft-grade aluminum, a material known for its strength. The aluminum is then anodized, which creates a hard, non-porous, and food-safe surface. This process adds color, prevents corrosion, and makes the parts easy to clean, ensuring no metallic taste gets in the way of your session.
What Sizes And Colors Are Available?
This set is designed for wide compatibility. It works with common bong joint sizes, including 14mm and 18mm, often using a rubber grommet for a tight seal on acrylic or ceramic pieces. To match your style, the set is available in 11 different vibrant, anodized colors.
The mix of an adjustable fit, tough material, and a complete set of parts makes this a great all-in-one upgrade.

How Do I Clean And Maintain It?
Keeping your aluminum downstem and bowl clean is key for the best taste and performance. Aluminum is tougher than glass against drops but needs simple, regular care.
How Do You Clean An Aluminum Downstem?
For a fast clean, unscrew the parts and rinse with hot water. For a deeper clean, soak the pieces in a mix of isopropyl alcohol and coarse salt for about 30 minutes. Use a soft pipe cleaner or brush to gently scrub any residue from the inside and threads. Rinse well with hot water and let it dry fully before putting it back together. Do not use harsh scrubbers, as they can scratch the anodized finish.
Proper cleaning ensures a neutral taste and keeps the threaded parts working smoothly for years.

Our description is super discrete and would be nearly impossible for any nosy lookers to determine what the transaction was for. On the credit card statement, our transactions show up as "Bays Online."
What is THCa?
THCa is regular THC. It's not like delta 8 or any other synthetic cannabinoid. All the products on this site are naturally grown cannabis-hemp. Cannabis naturally grows THCa, and when THCa is heated up, it becomes Delta 9 THC. To further clarify, all weed that you get in a dispensary has high levels of THCa (20-30%) and almost no Delta 9 THC. Because THCa is the "live" version, and Delta 9 is the heated up version.
Will This Get Me High?
Yes. Now stop asking questions and get to smoking 😂 THCa is the same as what you find in a dispensary, but we can ship it to you nationwide. It's legally considered hemp.
How Is This Legal?
All these products are grown and tested in compliance with the 2018 Farm Bill. Even though this is all regular pack, and will get you high. The farm bill only measures Delta 9, and all our products are THCa, just like regular fresh cannabis. If you have more legal questions, consult a lawyer as this is not legal advise.
