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

Works great. I am happy with the quality of the product. They fit on the primo jugs perfectly and I have no problem refilling them and carrying them without water slipping out.

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

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!

Works very well, great product

They pick up a large amount of dog hair. Hair sticks to these like magnets. I made the mistake of dropping the box and had to hand wash them for 10 minutes to get all the hair off. Also, maybe it’s me, but no one is lifting 50 pounds of water to pour out of the little hole, it’s basically useless. I tried; it’s messy and stupid. It leaked when put on its side, but my car stayed dry when driving the mile back from the filling machine up the road. That’s all that matters, if it does fall over I have enough time to pull over to set it upright without the car getting an internal bath. Since that’s the reason I got these and they do their intended purpose I’d recommend them. Just keep them in a drawer where they don’t collect any dust or dog hair. They are well made and do stay on, even when just quickly placing and throwing in the garage upright we’ve had no issues.

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.

Work great, less spills, good value

Fit perfect on 5 gallon water bottles and if you use a pump to get water. Makes mine sit perfect on top.

Worked exactly as I expected. Sealed tight with no drips.

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.

Work great, haul water all the time and they never leak, easy to put on and off

These fit very well and are easy to remove for sanitising etc... seal very well. Also recosable for the next bottle of water.

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.
