Worked perfectly for my garden hose plastic quick disconnects. It sure beats buying the sets all over or. For just pennies, I can breath new life into the plethora of quick-disconnects around my yard. I fear I'd have to buy expensive brass fittings to get reasonable life from garden hose quick disconnects. Now, I've doubled their life for a couple of bucks and I have tons to spare. If you are in the same boat, you've GOT to get these.

Each one of these little circles of perfection represents everything I've ever dreamed of in an o-ring. I only needed one, but now am am rich with an over-abundance, having 99 extra for a nominal fee.

Worked great for my vape charms. Very sturdy and stretched like I needed them to. I will buy them again.

Packaged well and works as expected. Used a belts for my P20 scroll saw since the original ones are impossible to find now. This is a great bargain since one belt for the saw is typically $20. Thank you very much.

453 o-ring should have 12" ID per description, but it actually was more like 14". Had to return it. Could not order another since any replacement would have the same order number and likely the same problem.

I purchased this product for a particular application and they perform without a hitch. Buying these in bulk from this seller is far more economical than running down the local hardware store.

I used these on a paintball marker where I had been destroying lots of O-rings. These have lasted much longer than the factory rings plus they are significantly cheaper.
