28mm Poly Seal Screw Caps [Bag of 12]

These are fantastic. Fit my 2 1/2 oz. French square bottles wonderfully. They are solid and strong. Also fit some larger sample bottles I have for trading whisky. Cannot beat the price. More than happy. As long as you know the exact size you need, they are great. Most of the private sellers wanted $8-13 to ship. This is a win win through prime.

I bought these caps to go with my amber boston bottles for my home made Kombucha. I got these in the event that I lost a cap or two and they are awesome quality. They are heavier duty then the caps that came with the bottles themselves and the cone really keeps in the carbonation well. I would reccomend.

I have a bunch of the 38mm “Poly Seal” caps for my 64 oz growlers and they fit and work just fine. I read through the details, questions and answers, saw 2 answers that said it would fit a half growler and took a gambled.Nope they don’t fit, solid plastic, feels nice, but they don’t fit the growler I got them for 😅. The 28mm measurement is the outer diameter of the cap and the outer diameter of the mouth of my growler is 28mm, I’m now thinking the 33 mm should fit my growler. I did ask if the outer diameter of the cap was 28mm but I didn’t wait for the answer. I’ll figure out something to do with 12 plastic caps 😅 it fits a standard 2liter soda bottle.Hope this helps someone 🤘🏽

They do the job on 1/2 and Gal Jugs Just be care full not to over tite and by 2 bages you will be glad you did I use them onMississippi Mud Bottles BobaneroBrew

I did lots of research before purchasing these and from what I gathered they would work for hot-fill-hold processing. That was NOT the case. All EIGHTEEN bottles I put up spoiled almost immediately. The conical seal separates from the cap very easily, and did on at least half of the bottles I had to pour out. I am so incredibly disappointed in this product. This cap may be ok as purely a "cap" but definitely not effective as a seal of any sort.

The ones that work work. About 25% of them break while twisting them on. That makes me think the other 75% may not last long. I’ll be looking for another supplier.

I needed replacement caps for my 16 ounce amber bottles. They fit perfectly.

I use these for all my cider bottles, great seal.
