2 Pack Original 5 Gallons Water Jug Cap, Fits 48mm|53mm|55mm Screw Tops|Threaded Tops, Reusable Universal Silicone Water Bottle Caps Non-Spill Top Lid Cover with Storage Box

Amazing fit like a glove over top of the 5 gallon water jugs and not to hard to take off also

These are great quality no leakage at all

I kept these case they are more flexible than the other product that I got and returned. Very easy to turn inside out like the instruction says to do. Except it is not completely leak proof. I still have to put a plastic Saran Wrap on my bottle, then the cap then this product over all of that.

These are great! I bought them hoping they would fit my 3 gallon glass water jug, and they do! I like that they are reusable and tight, but also easier to remove.

Currently rating it 3 stars, may go to 4 depending on its longevity. They take a little getting used to on install (yes, roll them inside out, place on jug mouth, then roll down the jug's neck), but turning a full 4 gallon jug upside down gave no leaks, not even a drip. I'm not a materials science major so I do not know the longevity of the material, especially in the dry environment of the American southwest (arid country). Will see if I need to upgrade the rating, let's hope.

Al fin hasta ahora encontré las que quería

Fit glass 5 gallon bottles perfectly

So I have a 3 rack for the 5 gallon jugs and all of them have the 48mm screw tops and all of them drip water since they lay on their side. The item description for these specifically say that it doesn't spill and it fits the 48mm tops but they don't work. Still drips and I've tried it with and without the screw top on. Frankly the design is specifically shaped for the snap tops not the screw tops so don't not buy these thinking they won't drip if you have the 48mm screw top bottles.

Stretchy but durable, and no leaks.
