BOTTLIT カラフェ 1L シリコーンパッキン

I was worried the old seal would keep leaking, but this replacement is exactly 40mm across and fits perfectly. The silicone is a bit firmer than I expected, which actually makes the lid close more securely now.

Snapped this right into the cap after the old one started leaking, and it's a perfect fit. The 8mm height and silicone material seal the lid tightly now with no drips. Exactly what I needed to fix my carafe.

The original seal on my carafe started leaking, and this silicone replacement fits perfectly—snapped right into place with no fuss. At barely two grams, it’s lightweight and the precise 40mm diameter made for a secure seal on the first try. Now the lid stays tight, and no more spills on my counter.
