【Upgraded】Morsatie Reusable 3 & 5 Gallon Water Jug Cap, No Leaking & Popping Open, Food Grade Silicone Replacement Cap for 55mm Standard/Screw/Crown Top Water Bottle & Water Pump Dispenser, 10Pcs

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.

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.

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

Great product! Easy to remove and re-apply! No more fighting and breaking nails with the hard plastic covers. No more painful cap removal. Thank you!

easy to use and good fit. defenetly recommad this and nice quality

Convenient, reliable and sanitary. Everything you could want in a reusable silicone jug cap. Going strong after years of use.

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.

I needed a topper that did not leak if the container was knocked over. This is the one. I have knocked over full 5 gal container and not a drop. Easy on and off.

First one leaked a little but that was us not fitting it on right. Now no issues whatsoever. Good product

These are fantastic! 100 x better than plastic caps. Easy to install and easy to remove. No leaks at all for me. I have a salt water tank due to evaporation I am pouring 2 to 4L of water into it daily - and it has to be reverse osmosis and chemical free water.

They work great!

Parfaitement étanche et s’adapte très bien au bouteille de 18 litres facile à installer

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.
