Acocony 1 1/4 Inch Rubber Cap (31.75 mm) Round Black Pack of 12

I use these to cover the electrode plates on my Ryobi 18v One+ battery packs. They fit snugly but are not difficult to get off. Keeps dust, dirt, oversprays off the plates and keeps them pristine. Worth every penny and not expensive to begin with. I will purchase again.

Bought these to cap off my dust collector pipe. Works great

Bonne qualité j'adore mes nouveaux capuchons

Though the caps worked perfectly for what I needed, I am somewhat disappointed in the order. The picture on Amazon shows two different sizes in the bag, the one that I wanted and a smaller version for a different application. I was planning on receiving both sizes because that is how it is advertised.

I was really surprised of the quality and the size. It's of true size, and easy to install. There's nothing to it. It was a perfect fit.
