Questions about the DAY OFF TUMBLER 900ml silicone ring
- What is the DAY OFF TUMBLER 900ml silicone ring for?
- It is a replacement part for your tumbler. The silicone ring helps maintain a secure fit for your drinkware, so it is the part to check when the lid no longer sits as it should. It is made from BPA-free silicone and comes in white.
- Which size do I need, small or large?
- The ring comes in two sizes: small at φ60 x H5 mm (approx. 4 g) and large at φ70 x H7 mm (approx. 6 g). The supplied information does not state which size fits which tumbler model, so measure the ring you are replacing and match the diameter and height to the closest size before ordering.
- How do I check that the new ring fits?
- Compare the old ring with the new one before fitting. The diameter and height should match the size you ordered, and the ring should sit in its groove without stretching or bunching. If it does not sit flat, stop and recheck the size rather than forcing it.
- Can I use this ring on other Kinto tumblers?
- The supplied information names the DAY OFF TUMBLER 900ml and does not confirm compatibility with other models. Treat it as a part for that tumbler unless the product listing states otherwise, and check the measurements against your own lid.
- How should I care for the silicone ring?
- The supplied information confirms only that the ring is made from BPA-free silicone and is white. It does not include washing, boiling, dishwasher or replacement-interval instructions, so follow the care guidance that came with your tumbler and avoid guessing at heat or chemical limits.
- When should I replace the ring?
- Replace it when the ring no longer sits properly or the lid stops holding as it should. The supplied information gives no fixed replacement schedule, so judge by the condition of the ring rather than a set number of months.
- Where is the ring made?
- The ring is manufactured in China and is available in a clean white color option.
