How it works
Three steps. No new bottle required.
1
Snap on
The flexible silicone cap fits many common 28mm beverage bottles. Press it on, twist a quarter turn.
2
Use the bottle
Squeeze, invert, hang, anchor, fill, or cut depending on the cap. The bottle does the rest.
3
Refit, refill, repeat
Pop it off when you’re done. The cap reuses on the next bottle. The bottle gets recycled.
Where it earns its place
The car, the bag, the campsite.
Six places CapTool gets used the most.
Beach
Sand off, before the car.
Rinse feet, gear, and dogs at the boardwalk so the back seat stays clean.
Pets
Muddy paws, handled.
One squeeze rinses paws after the trail before they hit the upholstery.
Camp
Camp dishes without a sink.
Quick rinse for dishes, hands, and gear when running water is two miles away.
Garden
Watering while you’re away.
The Drip cap turns a 1L bottle into slow-release plant care for the weekend.
Sports
Sticky hands at halftime.
Sideline rinse for orange wedges, cleat mud, and post-game cleanup.
Emergency
Hygiene when there’s no tap.
Three caps in a kit pouch. Hand rinse, water transfer, basic cleanup.
Honest fit
Fits many common plastic beverage bottles.
Every cap in the catalog uses the same 28mm beverage thread. We tested the most common US bottles. The full list is published and updated as new bottles get tested.
We don’t claim “universal.” The cap is built around the 28mm finish family with a flexible gasket that extends fit to nearby sizes. Test before regular use.

Common questions
Quick answers.
What bottles do CapTool caps fit?
Every cap in the catalog uses the same 28mm beverage thread. CapTool fits many common 28mm plastic beverage bottles, including most 16.9oz waters, 1-liter waters like Smartwater and Fiji, 2-liter sodas, and many sports drinks. The full tested list lives on our compatibility page. We don’t claim “universal” because bottle finishes vary by brand.
Is it safe to drink water that touches the cap?
The cap is made from food-contact-grade silicone, BPA-free, and meets FDA 21 CFR food contact requirements. Caps that contact water are designed for rinsing or controlled dispense, not for drinking through. The bottle itself is the drinking surface.
What does “the catalog grows” mean?
CapTool is built as a system. The 28mm bottle thread is the chassis, and we add new utility heads to the catalog every few weeks. Buy one cap. Come back for whichever next one solves a problem you have. The same bottles work across the whole line.
Can I use any cap for hot liquids, fuel, or cleaning chemicals?
No. CapTool caps are designed for water and standard beverage liquids only. Not for hot liquids, fuel, bleach, pesticides, hazardous chemicals, or pressurized contents. Each product carries its specific use guidance and safety language.
What’s your return policy?
30 days from delivery for any reason. Unused product in original packaging gets a full refund. Defects and damage covered with a prepaid return label and replacement. Full details on our returns page.
Do you sell wholesale to retailers?
Yes. Beach stores, pet retailers, garden centers, hardware, camping shops, craft retail, and emergency-prep distributors can request our wholesale packet with MOQs, lead times, and the full pitch deck.
For buyers and distributors
Built for shelf, kit, and gift.
CapTool fits beach, pet, garden, hardware, camping, craft, and emergency-prep aisles with one growing product family. Strong sell-through proposition, retail-ready packaging, full demo video library for in-store and online use.
