Pax Flat Mouthpiece

PAX Flat Mouthpiece — Spare Parts for Your PAX 2/3 Vaporizer

The PAX flat mouthpiece is a low-profile replacement mouthpiece designed for the PAX 2 and PAX 3 portable vaporizers. This pack includes 2 flat mouthpieces, so you've got a backup for your backup. If you've ever fished around in coat pockets or sofa cushions trying to find that tiny piece of silicone, you already know why spares exist.

Why You Need a Spare PAX Flat Mouthpiece

The flat mouthpiece is the part of your PAX that takes the most handling. You pop it off to load the oven, you pocket the vaporiser with it attached, you toss it in a bag. It's small, it's smooth, and gravity does the rest. We've seen plenty of customers come in saying they lost theirs at a park, a party, or just somewhere between the kitchen and the sofa. It happens.

The flat version sits flush against the top of the PAX body, which means it doesn't snag on pocket lining or collect lint the way the raised mouthpiece does. If you carry your PAX in a trouser pocket or a small bag, the flat mouthpiece is the better choice — it keeps the whole unit sleek and compact. The trade-off? The raised mouthpiece gives you a bit more lip comfort during longer sessions because it protrudes slightly. Both work identically in terms of vapour delivery; it's purely a form-factor preference.

Buying a 2-pack now means you're not stuck waiting for a delivery when one goes missing. At this price, it's the kind of thing you throw in the basket and forget about until you actually need it — and then you're very glad you did.

Flat vs Raised PAX Mouthpiece — Which One to Pick

The flat mouthpiece sits level with the top of the PAX, adding zero extra height. The raised mouthpiece sticks up about 5mm and gives your lips a more defined contact point. Here's how they compare:

We'd pick the flat mouthpiece for daily carry and the raised one for home use. If you only want one style, the flat is the more versatile of the two — it does everything the raised does, just with a slimmer profile. That said, some people genuinely prefer the feel of the raised version against their lips, and that's a perfectly good reason to go the other way.

How to Replace Your PAX Mouthpiece

1. Turn off your PAX and let it cool completely — the mouthpiece area gets warm during use, and you don't want to handle hot silicone.
2. Grip the current mouthpiece and pull it straight up. It's held in place by a magnet, so it should pop off with light force. No twisting needed.
3. Check the mouthpiece well for any herb residue or buildup. A quick wipe with a pipe cleaner or cotton bud dipped in isopropyl alcohol keeps the connection clean.
4. Drop the new flat mouthpiece into the well. The magnet will pull it into place with a satisfying click. Make sure it sits flush — if it's slightly raised on one side, just press it down gently.
5. Draw through the mouthpiece before loading the oven to confirm airflow is unobstructed. If the draw feels tight, check that the oven screen inside isn't clogged.

From Our Counter

We've sold PAX vaporisers since they first landed in Europe, and the mouthpiece is the single most-replaced part. Not because it breaks — the build quality is solid — but because it's roughly the size of a 2-euro coin and weighs next to nothing. People set them down while loading the oven and forget to put them back. One customer told us he'd lost 3 in a single festival weekend. The fix is dead simple: buy a spare pack, keep one in your PAX carry case, and you'll never be stuck.

One thing worth mentioning: the flat mouthpiece picks up less pocket fluff than the raised version, but it's still worth giving it a wipe before you use it if it's been rattling around loose in a bag. A bit of lint in the vapour path isn't harmful, but it's not exactly pleasant either. The PAX oven holds roughly 0.25g of ground herb (or up to about 0.35g packed tight in the PAX 3's deeper oven), so keeping that airpath clear makes a real difference to each session.
