In use

Slip the ring over the neck, wet the inside of the cap and press it on with a twist. To open, pull the ring. The caps fit snap, screw and crown tops with a 55 to 60 mm neck.

Check before you buy

  • The bottle neck measures 55 to 60 mm across
  • You refill your own bottles at a station or a store
  • Three caps or six: one for every jug you own

Pick another one if

Your bottle neck is narrower than 55 mm, as on most one-gallon jugs. These caps will not grip it.

What buyers say about the Silicone Jug Caps

    100% leak proof!

    Truly leak proof! I went through 2 other types of lids for my 5 gallon jugs, and these are the only ones that won't pop off or leak! They seemed a little pricey, but they are worth it! Don't waste your money on a cheap alternative, because this is the only one that works! I haul my jugs to the store to get filled almost every week and I no longer worry about them spilling in my car. You can hold a full jug upside down with this cap and not one drop will leak! They are so secure and actually take a little effort to remove. I have carpal tunnel and can still remove them, but it does take two hands for me. They are high quality and will last for years and years! Love them!

    Leaky loose fit, disappointing for storing water.

    Leaky. The caps do not seal and the 5 gallon bottle leaks at a fast rate. Disappointed in this purchase.

    Awesome water caps

    Don't fill bottles all the way to the top as there still is a little leakage if bottles are stored laying flat so leave a little extra room but overall the caps provide a snug fit. They have reduced water spill tremendously for me during transport from refill station.
