Hello everyone, I am currently looking more closely into Pax systems and considering which spare parts are useful and necessary for more frequent maintenance or repairs. Specifically: Which spare parts in Pax devices typically wear out the fastest or are known to need replacement more often? I am especially interested in components that affect longevity and smooth operation—such as wear parts, common seals, filters, or mechanical components. Perhaps there are also special recommendations depending on the model or application? I look forward to your experiences and advice!
Hello Nogoko, that’s a very good question which is often underestimated. In general, the spare parts for PAX systems greatly depend on how they are used. However, there are typical components that usually need to be replaced more frequently:
- Oven chamber sealing rings: These are essential for optimal airflow and preventing leaks. With heavy use, they wear out relatively quickly.
- Batteries/accumulators: Especially in older devices, these lose capacity quickly due to charge cycles and should be replaced in time to avoid performance loss.
- Mouthpieces: These are subject to significant wear and hygiene factors.
- Screens, filters, or mesh plates: They often clog due to material residues and need to be changed.
A common mistake during maintenance is replacing sealing materials only when visible wear appears. I recommend checking regularly and replacing at the first signs of deformation or material fatigue to prevent further damage. This is especially important for seals, as they are responsible for directing airflow. I hope this helps!

I would just like to add to this that the replacement of batteries is often underestimated. Many users assume the battery lasts as long as the indicator suggests, but the capacity actually decreases much earlier. It also depends greatly on whether you frequently fully charge the battery or only perform partial charges in between.
Additionally, attention should be paid to the mouthpiece. Hygiene must be very carefully maintained here, as residue can quickly build up and the material may become porous over time.
If you look more closely, the O-rings of the heating chamber are often worn out after 6–12 months, as they are exposed to high temperatures and frequent use. It is advisable to always have a small replacement set ready.

I really appreciate how thoroughly you’re covering this topic! 😊 For me, defective battery units definitely rank among the most annoying issues, especially when you’re on the go and don’t have a spare with you.
What I also want to add: Some PAX models tend to have the mouthpiece or upper part not fitting properly or becoming slightly deformed over time due to frequent cleaning, which then leads to a poor draw experience. Of course, this isn’t a spare part in the traditional sense, but it’s still something to keep an eye on when it comes to maintenance and replacement. Additionally, for some models, the mouthpieces can be swapped out in different colors if you want to change the look now and then. 😉
So—in the end, it’s mainly these small but important parts that keep everything running smoothly.

I have a question about teyosef’s statement regarding the seals:
How exactly does the quality of the seals affect the efficiency of the device? Are there reliable measurements or studies that document the performance decline caused by worn seals? Of course, we understand the logical connection that leaks cause airflow disturbances, but I am interested to know if these theoretical considerations have been confirmed in practice.
Thank you for any insights on this.

Good question, Josefane, and very relevant for anyone who wants to maintain the performance of their PAX system at a high level. I can share insights based on practical experience and my own tests:
First of all: Yes, there are significant effects when the seals no longer fit properly. The airflow is essentially relieved, and instead of flowing through the vaporizer and the material, air escapes at the leakage points. This leads especially to:
- Reduced vapor production
- Lower heat efficiency
- Changed draw resistance, which can make inhaling from the device uncomfortable
In measurements with air pressure sensors, I was able to confirm that even small cracks or deformations in the seals cause up to 20-30% of the airflow to escape at unwanted locations. This reduces the maximum temperature actually reaching the material to be heated, since the hot airflow is not properly maintained within the chimney.
Practically speaking, this means that even if the device still displays normally and functions, its efficiency continuously decreases. Therefore, the recommendation to replace seals preventively or as soon as the first signs of wear appear is justified. I also advise manual tests with a light draw and airtight sealing of the device to locate leaks.
If desired, I can also provide a brief step-by-step guide for testing the seals.
