Upgraded Morsatie 3 & 5 Gallon Water Jug Cap, No Leaking & Popping Open, 10

These are awesome! Definitely worth the money! I have a deep well at home. I work for a very small company, so finding ways to save on money whenever we can is a plus. My well water is better than anything you can buy in the store. We have a machine that takes 5 gallon bottles. With the original caps, if I turned a corner too fast, and the bottle tipped over, the cap would pop off, and my car would turn into a swimming pool! With these, I don't worry about that happening anymore. The fit is snug over the opening and down the neck. They don't have to be removed to use the bottle. There is a hole plug in the middle, that when you flip the bottle over and place it on top, pops the plug up into the bottle to let the water out, but has a ring on it to keep it from going into the bottle to float around. Or if you have a bottom feeding system with a straw tube, you just push the tub into the bottle.

Fit my 5 gallon jug of primo water perfectly had a hard time finding this was perfect and a good price

This cap is a little tricky to install, but it gets easy after a few times. And it’s totally worth it because this thing works like a charm. I can literally hold the bottle upside down and shake it, and not only does the cap stay firmly in place, but not a single drop of water will escape as I transfer the bottle to the dispenser. Absolutely tremendous. I love these.

Initially frustrated, but works great once you know the trick At first I was very disappointed — these caps didn't seem to live up to the "watertight" claim shown in the Amazon video, where they're rolled and set on their side without leaking. I tried the caps both ways (inside out and right-side out), and both times my bottle leaked water all over my floor. Turns out the issue wasn't the product — it was a missing instruction. None of the videos mention this key step: you need to make sure the inner seal/ring is securely pushed into the bottle opening first. That's what actually creates the watertight seal. Only after that should you pull the silicone sides down over the opening. Once I did that, the leaking stopped completely and the caps worked exactly as advertised. My advice to other buyers: don't give up if it leaks at first — check that the inner ring is properly seated inside the bottle opening before folding the silicone over. Wish this was shown in the product videos, as it would've saved me a very wet floor and a lot of frustration!

true to their size. They fit perfectly in my 5gallon water . Worth the price

These are excellent for the 3 & 5 gallon jugs for water dispensers. It is leakproof even if you carry the bottles sideways and the hole-stopper has a tight fit. I have more than I need but it's always nice to have extras if one ever breaks. I've had them for about 4 months and the ones I use haven't failed yet.

Fits very tight and seals the spout well. Easy to put on and it locks on to the lip when you push it down.

These seal great! Fit perfectly and love how the centre pops down but dose not fall down into the bottle! Great value!

They pay for themselves the first time you use them

Perfect fit and easy to use.

Works great. We have a 3 gallon water jug we travel with to go camping. No need to worry about it spilling over anymore. We can lay the jug on its side now while we drive, we don’t worry about it falling over when taking corners.

It does the job as designed except the plug falls into the jug each time. For some reason the retaining ring doesn't seem to stay attached to the inside of the cap as it's designed. Other than that, it works as intended. Seals well. No water leaks out as you invert the jug.
