Vape accessories
by Arizer
The Arizer mouthpiece is a replacement glass stem that restores your portable vaporiser to full working order in seconds. Available in four variants — Straight, Curved, With Tip, and a dedicated ArGo stem — each one doubles as both vapour path and herb chamber, with a built-in glass diffuser that cools your draw before it reaches your lips. If you've chipped, cracked, or shattered your original, this is the exact same part Arizer ships with their devices.
| Variant | Length | Key Feature | Compatible With |
|---|---|---|---|
| Straight | 110 mm | Clear glass, built-in diffuser — the standard stem most people know | Air, Air 2, Solo, Solo 2 |
| Curved | 115 mm | Clear glass, built-in diffuser — angled for a more relaxed draw position | Air, Air 2, Solo, Solo 2 |
| With Tip | 70 mm | Shorter stem with screw-on plastic mouthpiece tip — more compact, pocketable | Air, Air 2, Solo, Solo 2 |
| For ArGo | Compact (ArGo-specific) | Designed to sit flush with the ArGo's body for maximum portability | Arizer ArGo only |
Quick rule of thumb: if you liked your original stem, order the same shape. If you found the Straight a bit awkward to draw from while the unit sits on a table, try the Curved — the 115 mm angled design lets you sip without tilting the vaporiser. The With Tip variant is the shortest at 70 mm and slips into a pocket more easily, though the shorter vapour path means slightly warmer draws. And if you own an ArGo, there's only one option — the ArGo-specific stem — since the standard Solo/Air stems won't physically fit.
Glass breaks. That's not a design flaw — it's the trade-off you accept for clean, flavour-neutral vapour. Plastic and silicone stems exist for other brands, but Arizer chose borosilicate glass for a reason: it doesn't off-gas at vaporisation temperatures, it doesn't retain flavours between sessions, and it's dead easy to clean. The downside? One fumble on a tile floor and you're out of commission.
We've seen it happen more times than we can count. Someone's Arizer Solo 2 is working brilliantly, they set it down on the edge of a desk, the stem rolls, and that's the end of the evening. Having a spare mouthpiece in a drawer turns a disaster into a 10-second fix. Some people even keep one Straight and one Curved so they can switch depending on whether they're sitting at a desk or lounging on the sofa. At this price point, there's no reason not to.
One honest note: glass stems do accumulate resin over time, and that actually affects draw resistance. A fresh, clean stem feels noticeably more open than one you've been using for three months without a proper soak. If your current stem still works but feels "tight," try cleaning it before buying a replacement — 90%+ isopropyl alcohol and 20 minutes of soaking usually does the trick. But if it's cracked, cloudy, or chipped around the lip, don't risk it. Micro-fractures can cause a stem to shatter from thermal stress mid-session.
Every Arizer mouthpiece variant includes a built-in glass diffuser at the herb-chamber end. This isn't a separate screen or filter — it's part of the glass itself, with small holes that serve two purposes. First, they stop ground herb from being sucked into the vapour path. Second, they create slight turbulence in the airflow, which helps cool the vapour fractionally before it travels up the stem. The Straight (110 mm) and Curved (115 mm) stems give the vapour the longest cooling path. The With Tip variant at 70 mm is noticeably shorter, so expect a slightly warmer draw — still comfortable, just different.
The glass-on-glass connection between stem and oven is what makes Arizer portables stand out. There's no silicone gasket degrading over time, no plastic threading to strip. You push the stem in, the herb sits in the glass bowl at the bottom, hot air rises through it, and vapour travels up through clean glass. That's it. According to research published in Current Therapeutic Cannabis Controversies, newer vaporiser models — including those from Arizer — produced effective decarboxylation of herbal material (Lanz et al., 2016), which speaks to how well this simple glass-stem design actually performs.

Complete your setup: if you're ordering a replacement stem, it's worth grabbing a second one in a different style. The Curved variant pairs well with the Straight as a home-and-away combo. And if your Arizer's screens or o-rings are looking tired, check out the Arizer accessory range — replacing small wear parts at the same time saves you a second order down the line.
No. The ArGo uses a shorter, device-specific stem that sits flush with the body. Standard Solo/Air stems are too long and won't seat properly. Order the "For ArGo" variant if you have an ArGo.
Functionally, they're almost identical — same glass, same built-in diffuser. The Curved stem (115 mm) angles the mouthpiece upward, so you don't need to tilt the vaporiser toward your face. The Straight stem (110 mm) is 5 mm shorter and more compact. Pick whichever feels more natural for how you hold your device.
It works well, but the shorter 70 mm length means vapour has less distance to cool. Draws are a touch warmer compared to the 110 mm or 115 mm stems. The screw-on plastic tip does add comfort on the lips. It's the best option if portability matters more than cool vapour.
If it's not cracked or chipped, you don't need to replace it at all — just clean it regularly. Most people break one every 6–12 months through normal wear and butter-fingers moments. A clean stem with no damage performs identically to a brand-new one.
Not directly — the stem diameter doesn't match standard 14 mm or 18 mm joints. Arizer does make dedicated water pipe adapters for the Solo and Air series. If you want water filtration, grab one of those instead of trying to jury-rig a glass stem into a downstem.
Resin builds up inside the stem and around the diffuser holes, gradually restricting airflow. A 20-minute soak in isopropyl alcohol (90%+) clears it completely. If you vape daily, clean the stem once a week to keep draw resistance consistent.
No. The built-in glass diffuser replaces the need for metal screens — the small holes in the glass do the filtering. You won't need to buy separate screens for these stems.
