Roots Glass Thick Tree Perc Ash Catcher

Description

★ The 18/90 variant has a 14mm female bowl joint with an 18mm male joint that plugs into your piece

Roots Glass Thick Tree Perc Ash Catcher

An ash catcher that does the dirty work so your bong doesn’t have to. The tree perc pulls your smoke through a second round of water filtration — cooling it down and stacking bubbles before it ever reaches your main piece — while it traps the ash and resin that would otherwise gunk up your bong.

Built thick. This one stands 7″ tall and weighs around 300g, so it feels solid hanging off your joint instead of flimsy. Thick borosilicate glass takes daily use and cleaning without you stressing about a crack.

Two ways to run it. The 14/90 sits at a 90° angle on a 14mm joint. The 18/90 steps up to an 18mm connection and includes a 14mm bowl. Match it to your bong’s joint size and you’re set.

• Tree percolator for extra filtration and smoother, cooler pulls
• Traps ash and resin to keep your bong cleaner, longer
• Thick borosilicate glass, built for daily use
• 7″ tall, ~300g — solid, not flimsy
• 14/90 or 18/90 (90° angle) to fit your piece

Frequently Asked Questions

What does an ash catcher do?

It catches ash and resin before they reach your bong and adds a second stage of water filtration. Your hits run cooler and smoother, and your main piece stays clean far longer between scrubs.

What’s the difference between a 14mm and 18mm ash catcher?

It comes down to your bong’s joint. If your bong takes a 14mm bowl, run the 14/90. If it’s an 18mm joint, the 18/90 plugs in with an 18mm male end and comes with a 14mm bowl. Match the catcher to your bong’s joint and angle.

Does this ash catcher use water?

Yes — the tree perc works with a little water, same as your bong. Fill it just enough to cover the perc. That water is what cools the smoke and grabs the junk.

Will it fit my bong?

If your bong has a 14mm or 18mm female joint at a 90° angle (most beakers and straight tubes do), one of these two fits. Check your joint size and angle, then pick 14/90 or 18/90.

How do I clean it?

Same as any glass — iso and salt, give it a shake, rinse well. Because it catches the gunk first, a quick regular clean keeps your bong from ever getting bad.
