400 Pcs Rubber O-Rings Assortment Kit, 24 Sizes Rubber O-Ring Sealing Seal Assortment Set for Faucet, Hose, Automotive Repair, Plumbing, Gas, O Rings Kit

Looks like a good kit to have. many zises.

So far these 0-rings seem like a good product. They come in a nice array of sizes and thicknesses and have a little bit of flexibility so they are easy to apply use and create a good seal.

Worked great i bought to replace o ring on gas can and fit perfect and snug for good seal with no leaks. Good quality and great price for the variety of sizes

This o rings are so perfect and durable

I don't know what everyone else using them for- but they are great for threaded bbls. Put these on your firearms w threaded barrels and the muzzle device stays on snug!! All sizes for different ones!

I bought these to use as markers for my knitting projects, and they work perfectly, come in variety of ring sizes and the amount of rings in each size makes the value unbeatable. Some of the rings/markers that are marketed for knitting cost as much as 5.99$ for 10 rings, and the fancier ones are even more, so to have some in a variety of sizes could become quite costly. The plastic box they come in is well made and keeps everything organized! Although I can't testify to their original uses and how they perform as far stopping leakage. I highly recommend them as a gift for any knitter in your family!!

Exceptional Value! I needed a certain size O ring for a project. The hardware store sells them in packages of 1 for $1.01 plus tax! For 1 single tiny O ring! I purchased this assortment for about 9 bucks. Got a huge assortment that I can use for many projects. A fantastic deal!

Bought it thinking I could replace random orings I need to replace here and there... Wrong. They are all super thin
