do these have seals inside? I am looking to replace caps on Lifefactory 9oz glass bottles because their caps often leak as they haven't a rubber seal

They don't but on the Dr. Brown bottles they don't need them to seal completely. Not sure how they fit on other brands though.

No, they are solid with no removeable parts. They do not have a seal. I love these caps!!

The liters do not have seals on them. The 8.5 oz size have a A little tape seal. I know as a seller I tape down every bottle we ship to prevent leackage. Hope that helps.

I don't dsee why not. They have the regular canning seal caps. Seem they would be airtight. I believe these are the same design as any of their "canning" jars except that they are pretty light blue instead of clear glass.

No, they do not have caps to cover the spout. They also leak horribly! I returned mine...

Hi Chris, These doesn't have any seal just twist top. For the seal one you can purchase these ones: http://www.amazon.com/gp/product/B00CJWTN5U These tins have plastic/silicon kind seal in inside and it's water/air proof.

Not personally... even after many drops to hard surfaces, the rubber efficiently protects the glass.I highly recommend Lifefactory bottles!

Mine had lids as in the picture but did not have caps that would seal them closed.

YES ! The lids have an excellent seal ; BUT one of our containers came with a bad seal. Evidently at the factory the seal was not installed properly and was in a position to only seal about 60 percent of the lid. I could not find away or anyone who would take back the individual canister and replace it. They wanted the whole set ( once I found someone to commit to customer satisfaction ) so I just fixed it myself. No big deal. I would highly recommend this product, they do seal and are great to look at.

Yes, the seal does break just like regular caps. They may not break if the cap is placed on a bottle that is not the correct size, with the mouth being either too small in diameter of too small in height.

I've had good luck so far and not noticed any leaks from the threads. I put soy sauce, peanut oil and olive oil into them. As mentioned by others these did not come with caps.

Yes they do. But they are expensive. If you are not worried about the bottles being tampered with you can reuse the caps. I even use pop bottle caps and have not had one fail yet. The Mr. Beer caps will work just fine, but this is another way to save money. That was one of the reasons I started making my own beer. That, and the beer is superior to store bought beer.

Hello Nancy, I have good news for you. I just checked and they are the rubber seals. Great question I never even thought about that before I purchased them. They are also well constructed, You should be satisfied with the quality. I hope this helped you out. Have a Great Day!

Sean, sorry, it was quite a long time ago and I don't remember if there was a seal or not. Probably there was but I can't swear to it, and now I don't know if there was a manufacture date or use-by date on the bottle. Who knows if those little seals work or not, they aren't vacuum seals. And once you take off the seal, oxygen flows into the bottle. I assume the manufacturer is mass producing millions of capsules per week, and that the cartons of bottles are warehoused for up to 6 months or longer, as most everything is.

Yes, they do. I have 8 oz. glass bottles and 4 oz. plastic bottles and these caps fit all of them perfectly.

Yes there was a seal under the cap on the regular bottle that I purchased. However, there is no seal under the cap on the free bonus bottle of 30 that I received.

Yes, but I wouldn't recommend these. We bought two sets, and they all leaked every time. Not just a little leak, fluids stream out of them. We tried them with the life factory bottles & other glass bottles. All leaked terribly from the bottoms of the caps, & the spouts.

I have been feeding the capsules to our dogs, who have been doing well on them. I ordered another 3 bottles and they also did not have seals over the mouth of the bottle. It is bothersome that they do not have a method of protecting the contents of the bottles, but they are the same company which our Vet provided, so I have some confidence that the contents are safe.
