1. Remove the silicone cover
Loosen the silicone cover around the USB-C port, then take a firm grip of the silicone cover and slowly but firmly drag it up.
2. Adjust the top part
- Take a really firm grip of the top part and try to get it loose. You can use some force to do this.
- Check if any of the o-rings looks misplaced and if so - adjust them and lubricate with neutral vaseline or grease and place them back.
- Then fix the top part as hard as you can again (it does not need to be opened again so you can use some force here).
3. Thats it!
Well done! If airtightness has not improved, please check the other steps in our FAQ or contact us.
