Fit Check for 55mm Openings: Reusable silicone water jug caps designed for most 2, 3, 4, and 5 gallon water bottles with a 2.16" / 55mm opening. Works with many standard, snap-top, and crown-top jugs, plus some screw-top bottles. Bottle neck styles vary, so measuring before purchase helps confirm fit

6 Pack for Multi-Jug Rotation: Includes 6 reusable water jug caps for homes, office break rooms, garages, RVs, refill stations, and backup water setups. Keep extras ready when some bottles are in use, some are in storage, and others are waiting for the next refill trip

Helps Reduce Spills During Refill Transport: The flexible silicone body, center plug, and wraparound sealing rim help reduce splashes and leaks when moving full jugs from refill stations, loading bottles into your car, carrying them indoors, or swapping bottles at a water cooler

Easier Than Hard Disposable Plastic Caps: Soft silicone and side pull tabs make these reusable caps easier to press on, adjust, and remove than rigid one-time-use caps. Useful for frequent bottle changes at home water coolers, office dispensers, grocery refill stations, RV setups, and storage areas

Works with Many Coolers, Dispensers & Bottle Pumps: The center opening supports water flow on many compatible top-loading cooler spikes and also works with many bottom-loading dispenser tubes and bottle pump tubes. Water flow may vary by dispenser design. Caps may arrive folded; simply unfold before installation
