How Can I Be Sure I Need an 18mm Ash Catcher?

Not sure if your bong uses an 18mm bowl? You’re not alone. The easiest way to confirm size is to measure the outer diameter of your joint (if it’s male) or the inner diameter (if it’s female). A true 18mm joint often measures about 18.8mm, but this is typically rounded down to 18mm.

Just know that we also stock a great lineup of 14mm ash catchers for smaller bong bowls, so no matter the size of your glass bong, you can tap into the ash catcher benefits. 

Also - our expert team is here to help you confirm compatibility and make the right call so you can avoid the guesswork and stress of buying an 18mm ash catcher. So what are you waiting for? Shop now or get in touch with our customer service staff!

Frequently asked questions

What’s the right ash catcher size for my bong?

Measure the diameter of your joint and check whether it’s male (inserts into the ash catcher) or female (receives the ash catcher). Be sure to match both the joint size and angle (typically 90° or 45°).

What’s the difference between ash catchers and percolators?

An ash catcher is an external attachment that traps ash and adds filtration before smoke enters your bong. A percolator is typically built into the bong itself with the main goal of improving diffusion for smoother hits. Both are great, but they serve totally different purposes. 

What type of 18mm ash catcher is best?

That depends on your setup and preferences. A showerhead perc is great for reliable diffusion. A recycler ash catcher offers continuous water movement and extra filtration. Go for something minimal if you want fewer bubbles and more flavor.
