The G Pen Elite II Mouthpiece is a direct replacement part for the G Pen Elite II dry herb vaporizer — built from zirconia ceramic with an integrated filter screen and spiral vapour path that keeps your draws smooth and flavourful. If your original mouthpiece is clogged, cracked, or just past its best, this slots right in and brings the vaporizer back to factory performance.
The mouthpiece is the part of your vaporizer that takes the most abuse. It's in your mouth every session, it collects resin, and it's the first thing to show wear. A gunked-up mouthpiece restricts airflow, kills flavour, and makes your G Pen Elite II feel like a completely different (worse) device. We've seen customers come in convinced their vaporizer is broken when the actual problem is a clogged mouthpiece that just needs swapping out.
Zirconia ceramic is the material doing the heavy lifting here. It's the same stuff used in dental crowns — extremely hard, heat-resistant, and chemically inert. That last bit matters because it means the mouthpiece doesn't off-gas or impart any taste to your vapour, even at the Elite II's higher temperature settings (up to 428°F / 220°C). Compared to plastic or silicone mouthpieces on cheaper vaporizers, zirconia keeps the flavour profile of your herb clean and uncontaminated.
The spiral smoke path inside the mouthpiece is what separates the Elite II from simpler designs. Instead of hot vapour travelling in a straight line from chamber to lips, it winds through a helical channel. This extra distance cools the vapour down and gives particulates somewhere to settle before they reach your mouth. The result: smoother draws with noticeably less throat irritation. The built-in filter screen adds another layer of filtration, catching fine plant matter that would otherwise end up on your tongue.
One honest limitation: because of that spiral path, the mouthpiece does collect residue faster than a straight-tube design. You'll want to clean it regularly — a soak in isopropyl alcohol every week or two keeps it performing properly. If you let it go too long, the spiral channel gets restricted and you lose the cooling benefit entirely. That said, having a spare mouthpiece on hand means you can rotate between the two and always have a clean one ready.

Complete your setup: if you're replacing the mouthpiece, it's worth checking the condition of your G Pen Elite II screen filters too. A fresh mouthpiece paired with clogged chamber screens won't give you the airflow improvement you're after. The G Pen Elite II itself is also available if your unit has seen better days and you'd rather start fresh with a full vaporizer.
We get asked a lot whether replacement mouthpieces actually make a difference or if it's just a way to sell spare parts. Here's the honest answer: a clean, undamaged mouthpiece is the single biggest factor in vapour quality after the herb itself. The G Pen Elite II heats its ceramic chamber to your chosen temperature in roughly 30 seconds — that part works identically whether your mouthpiece is new or old. But once vapour leaves the chamber, everything depends on the mouthpiece doing its job.
A fresh zirconia ceramic mouthpiece with a clear spiral path delivers noticeably cooler, tastier vapour compared to one that's been in service for months without proper cleaning. The ceramic surface is smooth at a microscopic level, so resin doesn't bond to it as aggressively as it does to metal or plastic — but it still accumulates over time. Swapping in a replacement mouthpiece is the quickest way to get that "new vaporizer" feeling back without buying a whole new device.
The weight of the mouthpiece in your hand tells you something about the build quality. Zirconia ceramic has a satisfying density to it — it feels solid, not hollow. The filter screen is fine-mesh and sits flush inside the mouthpiece housing, so there's no rattling or loose parts. It clicks into the Elite II body with a firm, reassuring fit. No wobble, no air leaks around the seal.
The spiral vapour path is brilliant for cooling, but it does create more surface area for resin to collect. After every 5 to 7 sessions, remove the mouthpiece and soak it in 90%+ isopropyl alcohol for 15 to 20 minutes. Use a thin pipe cleaner or cotton swab to gently clear the spiral channel. Rinse with warm water and let it air-dry completely before reattaching.
If you vape daily, having two mouthpieces in rotation is the smartest move. While one soaks, the other is ready to go. You'll never have a session compromised by restricted airflow, and each mouthpiece lasts significantly longer when it's not being pushed past its cleaning threshold.
No. The G Pen Elite II mouthpiece is designed specifically for the Elite II and is not backwards-compatible with the original G Pen Elite. The housing dimensions and connection mechanism are different between the two generations.
With regular cleaning every 5 to 7 sessions, a single mouthpiece can last 6 months or more. If you notice restricted airflow even after a thorough isopropyl soak, or if the ceramic shows visible cracks, it's time for a fresh one.
Zirconia ceramic handles high temperatures without issue, but boiling water alone won't dissolve resin buildup effectively. Isopropyl alcohol at 90% concentration or above is the best option. Avoid using soap — it can leave residue that affects flavour.
Zirconia ceramic is chemically inert, meaning it doesn't release any compounds when heated and won't alter the taste of your vapour. It's also more durable than glass — you can drop it on a hard surface without it shattering — and more heat-resistant than most metals used in portable vaporizers.
The filter screen is integrated into the mouthpiece assembly and isn't sold separately. When the screen becomes too clogged to clean effectively, you replace the entire mouthpiece. Regular soaking in isopropyl alcohol extends the screen's usable life considerably.
