EHLE Funnel Bowl Turbo — The Bong Bowl Built for Bigger Hits
The EHLE Funnel Bowl Turbo is a wide-mouth borosilicate glass bowl piece that lets you pack substantially more flower than a standard cone or slide. Where most bowls top out at a modest pinch, this funnel bowl turbo EHLE design opens up to roughly twice the surface area, meaning thicker smoke and fewer reloads per session. If you've ever found yourself repacking mid-round while everyone waits, this is the fix. You can buy the EHLE Funnel Bowl Turbo in both 14.5 mm and 18.8 mm joint sizes to match your existing bong setup.
Which Joint Size Do You Need?
This bowl comes in two standard ground-glass joint sizes. Measure the opening on your bong's downstem — or check the specs that came with it.
| Variant | Joint Size | Fits |
|---|---|---|
| 14.5 mm | 14.5 mm male joint | Most mid-size bongs, smaller scientific glass |
| 18.8 mm | 18.8 mm male joint | Full-size bongs, larger beaker and straight-tube pieces |
Not sure? Grab a coin. If a one-cent piece sits inside the opening without dropping through, you've likely got an 18.8 mm joint. If it sits on top, it's probably 14.5 mm. Quick and dirty, but it works.

Complete your setup: A wide bowl like this pairs well with an EHLE glass bong or any scientific-glass water pipe with a matching joint size. If your downstem has seen better days, order a replacement diffuser downstem at the same time — better filtration means you actually taste what you're smoking instead of stale resin. Pipe screens are worth throwing in the basket too; they stop pull-through and keep your water cleaner for longer. A hemp wick is another smart add-on for corner-lighting a wide funnel bowl without butane taste.
Why the Funnel Bowl Turbo Beats a Standard Cone
The EHLE Funnel Bowl Turbo holds roughly twice the material of a typical cone piece, making it the better choice for shared sessions or solo smokers who dislike constant repacking. Standard bong bowls hold maybe 0.15–0.2 g of ground flower — a single personal hit. If you're sharing with mates, you're repacking every 30 seconds. The funnel shape on the EHLE Turbo opens the bowl diameter up significantly, letting you load a proper communal amount without building a precarious tower of herb that collapses into the water on the first pull.
The "turbo" part of the name refers to the airflow. A wider bowl with a well-placed hole means air draws evenly across the entire surface of your packed flower rather than tunnelling down the centre. The result: more complete combustion, thicker smoke, and less wasted green stuck to the sides. We've used narrow cones where half the bowl stays unburnt and you end up stirring it with a lighter corner like some kind of archaeologist. The funnel shape genuinely solves that.
Then there's the glass itself. EHLE is a German glassblower that's been making scientific-grade borosilicate pieces for years. Borosilicate glass handles thermal shock far better than soda-lime glass — the cheap stuff that cracks when you heat it unevenly. You can torch this bowl repeatedly without worrying about stress fractures. It's noticeably thicker in the hand than a no-name bowl from a bargain bin, and the ground-glass joint seats cleanly without wobble. According to EMCDDA harm-reduction guidance, using clean glass accessories and maintaining equipment regularly contributes to safer consumption practices.
How to Use the EHLE Funnel Bowl Turbo
Using this bowl correctly takes about 30 seconds of setup and makes a noticeable difference in smoke quality from the very first hit.
- Check your bong's joint size — 14.5 mm or 18.8 mm — and make sure you've ordered the matching variant.
- Grind your flower to a medium consistency. Too fine and it pulls through; too coarse and you get uneven burn. A metal or glass screen at the bottom of the bowl helps if your grind runs fine.
- Pack the funnel bowl loosely at the bottom and slightly firmer towards the top. You want air to flow through, not a compressed brick. Fill to just below the rim — overpacking defeats the purpose of the wide design.
- Seat the bowl into your bong's downstem. The ground-glass joint should create a snug, airtight seal with a gentle twist. No forcing needed.
- Light the edge of the bowl — not the centre — and draw slowly. The turbo airflow design pulls flame across the surface evenly. Corner-lighting extends the life of a packed bowl when sharing.
- To clear, lift the bowl from the downstem and inhale the remaining smoke from the chamber.
- After your session, tap out the ash and give the bowl a rinse with warm water. For deeper cleaning, soak in isopropyl alcohol and coarse salt for 15–20 minutes, then rinse thoroughly.
Keeping Your Funnel Bowl Clean
Regular cleaning after each session prevents resin buildup and keeps every hit tasting fresh rather than stale. Borosilicate glass doesn't absorb residue the way silicone or acrylic does, so a quick rinse with warm water goes a long way. For weekly maintenance, a 10-minute soak in 90%+ isopropyl alcohol dissolves resin buildup without scrubbing. Drop in a tablespoon of coarse salt as an abrasive, cover the openings, shake, rinse with hot water. The wide funnel shape actually makes this bowl easier to clean than narrow cones — you can get a finger or pipe cleaner right in there without awkward angles.
Avoid using boiling water directly on cold glass. Borosilicate handles thermal shock better than standard glass, but "better" doesn't mean "immune." Run warm water first, then increase the temperature gradually. Your funnel bowl turbo EHLE will last years this way.
Frequently Asked Questions
Will the EHLE Funnel Bowl Turbo fit my bong?
If your bong has a standard 14.5 mm or 18.8 mm ground-glass joint, yes. These are the two most common sizes in scientific glass. Measure your downstem opening or check your bong's specs. Silicone bongs with glass-on-glass adapters also work.
What's the difference between 14.5 mm and 18.8 mm joint sizes?
The number refers to the outer diameter of the male joint on the bowl. 14.5 mm is the smaller size, common on mid-size and portable bongs. 18.8 mm is the larger size, standard on full-size beaker bongs and straight tubes. They are not interchangeable — a 14.5 mm bowl will rattle around in an 18.8 mm downstem.
Do I need a screen with this funnel bowl?
Not strictly, but we'd recommend one — especially if you grind fine. A small glass or metal screen sits in the bottom of the bowl and stops material from pulling through into your water. Keeps your bong cleaner and saves you from inhaling ash.
How much flower can the Funnel Bowl Turbo hold?
Roughly double what a standard cone bowl holds. Expect to pack around 0.3–0.5 g comfortably depending on grind consistency and how firmly you pack. It's built for group sessions or for anyone who doesn't want to reload constantly.
Is borosilicate glass really more durable than regular glass?
Yes. Borosilicate glass contains boron trioxide, which gives it a much lower thermal expansion coefficient than soda-lime glass. That means it resists cracking from repeated heating and cooling. It's the same type of glass used in laboratory beakers and high-end cookware. It's not indestructible — drop it on tiles and it will break — but for normal use with a lighter or hemp wick, it handles the stress without issue.
Can I use this bowl with a dab rig?
This is a dry herb bowl, not a banger or nail. It's designed for flower, not concentrates. If you want to dab, you'll need a quartz banger or titanium nail in the matching joint size instead.
How do I clean resin out of the funnel bowl?
Soak it in isopropyl alcohol (90% or higher) with a pinch of coarse salt for 10–15 minutes. Shake gently, then rinse with warm water. The wide funnel shape makes cleaning easier than narrow bowls — you can reach the inside walls without specialised brushes.
Where can I buy the EHLE Funnel Bowl Turbo?
You can get the funnel bowl turbo EHLE right here at Azarius. We stock both the 14.5 mm and 18.8 mm variants and ship from the Netherlands.
