How to Use CapSealer™

Stopping bottle leaks is easier than you think. CapSealer™ works in just 3 simple steps — no tools, no mess, no ruined clothes.

Step 1 — Remove the Cap

Unscrew the cap from your bottle of shampoo, lotion, sunscreen, or any other screw-top toiletry.

Step 2 — Place CapSealer™ Over the Opening

Take one CapSealer™ seal and place it flat over the bottle opening. The flexible material wraps around the threaded top and molds to it, creating a tight, custom seal.

Step 3 — Screw the Cap Back On

Replace the cap and screw it back on as normal. As the cap tightens, it presses the seal firmly against the threads for a leak-proof fit. That's it — travel-ready!

Will It Fit My Bottle?

Each CapSealer™ seal is 2.5 inches (approx. 63mm) in diameter — larger than most standard bottle openings. The flexible seal extends over the threaded neck of the bottle and molds around it as the cap is screwed on, creating a tight, secure fit regardless of the exact opening size. It works with most standard threaded bottle necks.

How Long Does a Seal Last?

Because CapSealer™ molds to the specific threads of your bottle, it works best when kept on the same bottle. It is not designed for repeated reuse across different bottles. Over time and with repeated cap removal, the seal will wear and should be replaced. We recommend keeping a fresh supply on hand — that's why the 25-Pack and 50-Pack are such great value for frequent travelers!
