Rubber sealing rings made of natural rubber and chalk
✔ 3 colours per purchase
✔ metallic colourants
✔ no plasticisers
Made in Germany
The rubber producer created a compounded rubber for Soulbottles that is free of all petrochemicals. Standard ‘natural rubber’ consist of 20% natural rubber and 80% plastics, while the Soulbottles sealing rings are 80% natural rubber and 20% non-harmful chalk, binding agents and pigments.
At present Soulbottles is working on finding a source for Fair Trade natural rubber, a process that is turning out to be more difficult than anticipated.
If you want different coloured sealing rings, we also have a set of pink, purple and red ones.
Do not allow the ring to come into contact with oils in order to prevent accelerated wear.
