Blue Dew Cap Replacement (2Pk)

These are great!

We bought these caps to fit our glass 5 gallon carboy to keep the water from spilling out when we transport our water from the store to our home. The caps came super fast and they even wrote "Thank you Rosie" on our receipt which was a nice personal touch. The caps fit perfectly on our 5 gallon glass bottle and work well for what we needed them for.

The cap fits quite snugly, but if you are strong enough to wrestle a 5 gallon bottle of water you should have no problem getting the cap on and off. On the other hand when a nearly full bottle fell from our van to the pavement the cap stayed on the bottle and didn't leak. I am very happy with this cap.

These are an extremely, and I mean extreme, tight fit! Once you get them on, it is extremely difficult to get them back off again. They were even difficult to put on. But they work very well once you do it.

It doesn’t fit the standard 3 gallon bottles. It fits way too tight and removing the cap is insanely hard once you manage to put it on.

I needed something that would seal well and be removable. These fit the bill. They're a little tough to remove but have never popped off on their own. Never had a spill either. So they're perfect for my use. I bought more for new carboys after a couple of years of using 3 of these.

Doesn't fit my water bottle.

These work great for transporting your 5-gallon (or smaller size with same mouth opening size) bottles to refill. I used these to take my bottles to the grocery store and fill them up with filtered water at $0.39/gallon vs. paying almost $7/gallon from the water delivery company. The lids keep the water from splashing while in transit. Don't know if they would stay on if the bottle actually tipped over, but with the weight of the water I have never had to find out.
