Bongs vs. Dab Rigs: A Buyer's Guide

They look similar enough to confuse — both glass, both full of water — but a bong and a dab rig are built for two different things. Here's what actually separates them, and how to pick the right one.

25 October 2026·5 min read

Walk past our paraphernalia case and it's easy to assume every water pipe in there does the same job. It doesn't. The water chamber, the downstem, the glass — all of that is shared. What's different is the piece on top, and that one difference decides what the whole thing is actually for.

So what's the real difference?

A bong is built for flower. You pack a bowl, light it, and inhale as the smoke bubbles through water on its way to you. A dab rig is built for concentrates — wax, shatter, rosin, diamonds — and instead of a bowl, it has a banger or nail that you heat first, then touch the concentrate to. The water chamber and downstem work the same way in both; the only structural difference is what sits on top, and that single swap is why you can't just drop a dab-friendly nail onto any old bowl piece and expect it to behave.

Dabbing is also just a few more steps than smoking flower. You're heating a nail with a torch (or letting an e-nail do it for you), waiting for it to cool to the right temperature, then touching concentrate to it and inhaling as it vaporises. A bong, by comparison, is pack-and-light.

What's actually in a banger, and does the material matter?

The banger (or nail) is the small bucket-shaped piece you heat and dab into. The material changes how it heats, how long it holds heat, and what it does to flavour:

On heat itself — a glass or quartz nail is typically heated to somewhere around 545–570°F, then given roughly 60 seconds to cool before you dab, since dabbing straight off the torch will just burn the concentrate. Titanium holds heat differently and only needs about 10 seconds. Lower temperatures (sub-500°F territory) tend to preserve more flavour; push past 570°F and you'll get a bigger, harsher hit instead. There's no single "correct" number — it's a trade-off between flavour and intensity, and most people land somewhere in the middle through trial and error.

Butane is the standard torch fuel here — propane burns hotter than nail materials are generally built to handle, and can damage glass or titanium over time. If you're buying a torch specifically for dabbing, a butane one is the safer long-term choice.

What does a percolator actually do?

"Perc" gets thrown around a lot without much explanation, so here's the short version: a percolator is an extra piece of glass inside the water chamber — a disc, a set of arms, a stack of slits — that breaks your smoke or vapour into smaller bubbles before it reaches you. Smaller bubbles mean more surface area touching water, which means more cooling and more filtration before you inhale. The trade-off is drag: more percolation generally means a harder pull, which is why some people who want a quick, straightforward hit skip percolators altogether and stick to a plain bong.

The common types you'll come across:

None of this is required to get a good hit — plenty of people are perfectly happy with a straight tube and no perc at all. It's a smoothness-versus-simplicity call, not a right-or-wrong one.

What does joint size actually mean, and why does it matter?

Every bowl, banger, or downstem has to physically fit the piece it's going into, and that's governed by joint size — the diameter where the two parts meet. The three sizes you'll see are 10mm (small rigs and mini bongs), 14mm (the most common size for both bowls and bangers — if you're not sure, this is the safe default), and 18mm (bigger bongs built for bigger hits). Joints also come in male (narrows and slides into the other piece) or female (wider, receives the other piece) — a female rig needs a male bowl, and vice versa — and at either a 90° or 45° angle, which affects how upright the bowl sits once it's in. Mismatched sizes aren't necessarily a dealbreaker: an adapter (commonly 18mm-to-14mm) can bridge the gap if you already own a piece in a different size to what you're buying.

How do you actually keep one clean?

Resin builds up in the water chamber and percolator whether you're smoking flower or dabbing, and it affects taste long before it looks bad. The standard home method: empty and rinse the piece with warm (not hot — hot water can stress the glass) water, fill it with isopropyl alcohol (91% or higher) and a coarse salt like sea salt, cover every opening, and shake gently for 30–60 seconds. For heavier buildup, let it sit for 10–30 minutes before rinsing again. A cotton swab or pipe cleaner handles any stubborn spots the shake-and-rinse doesn't reach. Rinse thoroughly afterward and let it dry fully before using it again — any leftover alcohol fumes are not something you want to inhale. Once a week is the general rule of thumb for keeping taste and performance from drifting.

So which one should you actually buy?

If flower is mostly what you smoke, get a bong — a dab rig gains you nothing there and just adds steps. If you're regularly working through concentrates (wax, rosin, or diamonds), a rig with a decent banger is worth the extra setup. And if you genuinely do both, it's worth knowing a bowl and a banger of matching joint size can often share the same base piece, so you're not necessarily buying two full setups from scratch. Where percolators fit in is really about how much drag you're willing to trade for extra smoothness — there's no wrong answer, just a personal one.
