Water pipes & bongs
by EHLE
A silicone cleaning plug seals your bong's carb hole so cleaning solution stays inside the chamber instead of leaking out. The EHLE Silicone Cleaning Plug is a small, flexible stopper measuring 20mm across that fits carb holes from 12.5mm to 16.5mm — covering most standard water pipes without fuss. No more cupping your hand over the opening while isopropyl alcohol sloshes everywhere.

Pair this plug with EHLE glass bongs for a matched setup, or grab a bottle of bong cleaner to make the whole process quicker. A set of cleaning brushes rounds out the kit nicely — plug the hole, fill with cleaner, shake, brush, rinse. You can buy all of these items separately in the Azarius bong accessories category.
A silicone cleaning plug creates a compression seal that keeps cleaning solution locked inside your bong chamber, turning a messy two-person task into a quick solo job. Without plugging the carb hole, you pour in your cleaning solution, give it a shake, and half of it leaks straight out onto the table, your trousers, or worse — the carpet. We've watched it happen in the shop more times than we can count. Customers come back smelling of isopropyl and frustration.
This plug addresses that problem in about one second flat. The silicone is soft enough to compress into the hole and form a watertight seal, but firm enough that it won't pop out when you shake the piece. It weighs practically nothing — you'll barely notice it in a drawer — and because it's silicone, it won't scratch or chip glass. EHLE makes solid glassware, so it's no surprise their accessories are equally well thought out. According to the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA), harm-reduction practices include keeping paraphernalia clean, and a proper seal during cleaning makes thorough maintenance far more likely.
The honest limitation? It only fits carb holes between 12.5mm and 16.5mm. If your bong has an unusually large or small carb, measure first. A 20mm plug won't seal a 20mm hole — it needs to be bigger than the opening to create that compression fit. For standard EHLE pieces and most mid-range bongs, though, you're sorted.
Using the plug takes under a minute: press it into the carb hole, add cleaning solution through the downstem, shake, and rinse. Here is the full step-by-step process.
The single most common reason people let their glass get grimy is that cleaning feels like a hassle — we hear it daily at the counter. We've sold bongs since 1999, and a plug like this turns a messy job into something you can do solo in under five minutes. The best bong cleaning accessory is the one that removes excuses, and if you buy an EHLE silicone cleaning plug at this price point, there's really no reason not to have one in your kit.
Compared to using cling film and a rubber band (yes, we've seen it), a purpose-built silicone plug is tighter, faster, and doesn't leave sticky residue on your glass. Compared to cork stoppers, silicone won't crumble over time or absorb odours. We'd pick this over both every time. Order one alongside a bottle of EHLE cleaning solution and a brush set from the Azarius cleaning accessories category for the complete maintenance kit.
Yes, as long as your carb hole measures between 12.5mm and 16.5mm. Grab a ruler or caliper and check before ordering. Most standard bongs fall within this range.
Technically yes — it blocks the carb hole. But it's designed for cleaning. During a session, you want quick finger access to the carb for airflow control, which a plug slows down.
Warm water and a bit of soap. Rinse, air dry, done. Don't soak it in acetone or other harsh solvents — they can degrade silicone over time.
Silicone is durable and reusable. With normal use and gentle cleaning, one plug should last years. There's no expiry date on this thing.
This plug won't seal properly. You'd need a larger stopper — look for plugs in the 25mm+ range, or use a piece of food-grade silicone sheet cut to size as a temporary measure.
No. Food-grade silicone is inert and odourless. After rinsing your bong post-clean, there's zero residual taste or scent from the plug.
