Screen Notch Bowl by EHLE — The Fix for Screens That Won't Stay Put
The Screen Notch Bowl is a borosilicate glass bowl piece by EHLE that uses a precision-machined groove to hold a standard flat pipe screen firmly in place. If you've ever had a screen pop loose mid-light and sent a hot ball of ash straight into your water pipe, you already know why this exists. Available in 14.5 mm and 18.8 mm joint sizes, it drops straight into any standard ground glass bong or water pipe for an airtight, wobble-free fit.
Which Joint Size Do You Need?
Measure the female joint on your water pipe — that's the opening the bowl slots into. A 14.5 mm joint is roughly the diameter of your little finger; an 18.8 mm joint is closer to your index finger. Still not sure? Pull out your current bowl piece and check the stamp on the joint. Most standard-size bongs from EHLE, Weed Star, and similar brands use 18.8 mm. Smaller or more portable rigs tend to run 14.5 mm.
| Variant | Joint Size | SKU | Best For |
|---|---|---|---|
| 14.5 mm | 14.5 mm male joint | HS1227 | Smaller bongs, bubblers, compact rigs |
| 18.8 mm | 18.8 mm male joint | HS1228 | Full-size bongs, beaker bases, straight tubes |

Complete your setup: grab a pack of Steel Pipe Screens in the right diameter so you've got spares on hand — screens wear out faster than you'd think, especially if you're cleaning with a lighter flame. If your water pipe could use a general refresh, a set of Bong Cleaning Plugs and some Isopropyl Cleaning Solution will have the glass looking brand new in minutes. You might also want to browse the Bong Bowls and Accessories category for downstems and adapters that pair well with EHLE glass.
Why a Screen Notch Bowl Solves the Loose Screen Problem
A screen notch bowl addresses the single most common frustration with standard glass bowls: screens that shift, tilt, or pop out during use, letting ash and herb pull straight through into your water pipe. Here's how that problem usually plays out.
Standard bowl pieces have a flat bottom with a hole (or a few holes). Drop a screen in and it sits there loosely. Poke at your herb with a lighter or a poker tool and the screen tilts. Pack the bowl a bit too firmly and the screen gets wedged at an angle. Over a few sessions, the screen warps from heat and stops sitting flat altogether. The EHLE Screen Notch Bowl addresses this with a single design change: a machined groove that the screen edge clicks into. The screen stays level, stays centred, and doesn't shift when you're loading or lighting. It's a small detail, but it's the kind of thing that makes you wonder why every bowl piece isn't built this way. According to harm-reduction guidance from the EMCDDA, using proper filtration and well-maintained equipment is a basic step toward reducing the intake of combustion byproducts when smoking through water pipes.
One honest note: this bowl doesn't come with screens included. You'll want to pick up a set of flat brass or stainless steel pipe screens in the correct diameter. The groove is designed for standard round screens — nothing proprietary, nothing expensive. Also, because the notch holds the screen so firmly, you might need a poker or paperclip to pop the screen out when it's time for a swap. That's the trade-off for a screen that actually stays where you put it.
How to Use the EHLE Screen Notch Bowl
Using the screen notch bowl takes about 30 seconds to set up and requires no tools beyond a standard flat pipe screen and your water pipe. Follow these steps.
- Select the right joint size — 14.5 mm or 18.8 mm — to match your water pipe's female joint.
- Take a standard flat pipe screen and press it into the bowl. You'll feel it click into the notch groove around the inner rim. The screen should sit flat and level without any wobble.
- Dry-fit the bowl into your bong's joint. It should slide in smoothly with a slight twist. A proper ground glass joint creates a near-airtight seal — no rubber grommets needed.
- Load your herb on top of the screen. Because the screen is locked in place, you can pack with a bit more confidence than usual without worrying about pushing it sideways.
- Light and draw. The screen filters particulate while staying firmly seated — no ash shooting through into your water.
- To clean, soak the bowl in isopropyl alcohol for 20–30 minutes, then use a poker or paperclip to pop the screen out of the notch. Rinse with warm water and let it dry before reassembling.
