Honest fit

Compatibility list.

The bottles we’ve tested with CapTool Rinse. Updated when new bottles are added or removed.

Last updated: May 2026. CapTool is built around the 28mm beverage finish family with a flexible silicone gasket that extends fit to nearby sizes. Test fit before regular use. We don’t claim “universal”; bottle finishes vary by brand.

A note on “universal.”

We don’t use the word until testing supports it across every common bottle finish, and even then only after legal review. The list above reflects current testing. New bottles get added as we test them. If a bottle you use isn’t listed, tell us and we’ll add it to the queue.

Reporting a fit issue.

If a bottle on this list doesn’t fit yours, batch variation may be the cause. Email support@trustncredibility.com with the bottle brand, size, and a photo. We’ll replace the cap or refund.
