5-Pack (Same Size) Solid Rubber Stoppers - Size #8-42mm (1.65in) x 32mm (1.25in) - 30mm (1.18in) Long - Black Lab Plug

I needed a stopper to replace one that belongs to the first of two hummingbird-water-mixing bottles I've owned for years. It has to resist water at near the boiling point and to fit snugly in the heavy glass bottle in which I mix the Secret Sauce. These stoppers met the need perfectly. And now I've got spares. Great little product.

Rubber stoppers, what's to say? No problems, size is as specified, they are indeed black.

No leaks. Would buy again.

These worked fine for my needs, although they are unusually heavy. Other than that, they fit tight, and served my purposes. Considering I didn’t have many choices for this size holes, I would recommend. But if you can find other plugs that fit your home size, I would probably not recommend these.

Good quality

I make my own soy milk and decided to store it in my collection of vintage milk bottles. I wanted a cap for the bottles (to prevent odor, and also so I could shake it) and these work perfectly.

Purchased the rubber stoppers to replace silicone stoppers that would not stay in my fermentation jugs no matter how firmly installed. Left 3 solid but drilled out the others to allow air locks to be installed.

They fit
