The 18″ Multi-Perc XL ST is a tall, heavy-hitting glass bong built for people who want extra-smooth pulls without babying their piece. At 18 inches (457mm) with stacked multi-perc diffusion and an 18mm joint, it’s made for daily drivers who like big chugs that don’t feel harsh. This one’s all about clean function, stable footing, and a splashguard that actually keeps the water out of your mouth.
Why You’ll Love It
-
Smoother, cooler hits — Halo popped hole percs break up the smoke into tiny bubbles so your lungs get less heat and more flavor.
-
Less splash, more stash — Built-in splashguard keeps the water line in check, even when you clear it hard.
-
Stays put on the table — Wide, colored foot gives you a solid base so you’re not stressing every time someone bumps the coffee table.
-
Easy to grip, easy to pass — Double Maria neck adds handholds so this tall piece never feels awkward when it makes the circle.
-
Dialed-in 18mm joint — Standard 18mm female connection plays nice with your favorite bowls, ash catchers, and bangers.
-
Looks as good as it rips — Color accents on the lip, waist, and base give it that “display piece” vibe instead of generic glass tube energy.
-
Built for real use — Thick glass and a reinforced design make it a legit daily driver, not a fragile shelf queen.
Best For
This piece is made for bong heads who actually care about function and not just height flex. If you’re running multiple bowls a night and want each one to feel smoother than a basic straight tube, this is your lane. It’s also a strong upgrade if you’re moving up from a smaller water pipe and want something that can hang with the rest of your smoke shop gear without coughing you into next week.
How to Use It
Fill the base with enough water to cover the halo popped holes on the percs, but don’t overdo it or you’ll lose the benefit of the splashguard. Load your favorite bowl or drop in an 18mm banger, and let the multi-perc stack do its thing as you pull—those extra bubbles are what make the hit feel softer and more controlled.
The double Maria neck gives you an easy grab point when you’re passing it or clearing a big snap, and the wide foot keeps everything planted. If you’re the type who runs a whole setup, park this on a nonstick dab mat so you’re not grinding glass on the table or dripping water everywhere.
When you’re done for the night, a quick rinse with warm water goes a long way. For heavier build-up, let it cool completely, then use isopropyl alcohol and a rinse to bring the glass back to clear. Keeping the percs clean is what keeps that smooth function going.

Fit & Compatibility
The 18mm joint makes this bong super flexible with your existing setup. Any standard 18mm male bowl, dropdown, ash catcher, or banger will plug right in without extra adapters. If you’re mostly into flower, pair it with your favorite slide and, if you want to baby the glass, consider adding a simple accessory like an ash catcher from your wider accessories collection to keep those percs cleaner longer.
FAQ
-
Q: Does this come with a bowl?
A: The product listing will show what’s included, but the joint is a standard 18mm female, so any 18mm male bowl you already own will work if you want to swap pieces around.
-
Q: Will this be too tall for everyday use?
A: At 18 inches (457mm), it’s definitely a full-size piece, but the wide base and double Maria neck make it easy to handle. If you’re used to smaller rigs or hand pipes, it’ll feel bigger—but the payoff is cooler, smoother rips.
-
Q: Can I use this as a dab rig?
A: Yes, just swap the bowl for an 18mm banger or nail setup. Plenty of dabbers like running a bigger bong for extra cooling, especially if they already use smaller dedicated nectar collectors for travel or quick hits.
-
Q: How do I keep the percs from clogging?
A: Change the water regularly and don’t let reclaim sit for weeks. When it starts to look hazy, rinse it, then soak with isopropyl alcohol, rinse well, and let it dry before you sesh again. Keeping those halo holes clear is what keeps the diffusion strong.
-
Q: Will an ash catcher affect how it functions?
A: An 18mm ash catcher will add a little drag but also helps keep the main chamber cleaner, which is huge with multi-perc pieces. Just be mindful of added weight on the joint and try not to overload it—especially if you’re also using heavier glass like thick concentrate jars nearby on the same surface.
-
Q: Is this hard to clean because of all the percs?
A: Multi-perc pieces always take a bit more patience than a simple beaker, but regular rinses and the occasional alcohol soak keep things manageable. If you’re already working with rosin or hash and using things like parchment paper, treating this piece with the same “clean as you go” mindset makes a big difference.
-
Q: Is the glass thick enough to feel solid?
A: The 18″ Multi-Perc XL ST is designed as a serious daily driver, not a thin novelty tube. The colored base and reinforced areas give it a stable, substantial feel so you’re not nervous every time someone sets it down a little too hard.
