Normally, I would never purchase anything in an assortment pack as I know I'll likely never find a use for all the different sizes and types. Think assorted screws, nails, buttons and so on. However, I needed to replace the grommet for the mass airflow sensor for my 2007 Jeep JK as the original had rotted away. Just try and confidently find the right size. I got swayed into purchasing this assortment as I found I was constantly digging into my sons box of assorted shrink tubing I was needing for different projects. (I finally bought my own assortment as well as a replacement box for my son.) Maybe an assortment of grommets might be handy too.Some of the larger grommets are solid (but thin) in the center which makes them perfect for running wires from the engine compartment through the firewall into the cabin. They would have been handy when I installed my rock lights and CB, but that was years ago. We've got a lot of wiring to do on my son's old CJ so no doubt these grommets will come in handy in doing things properly.These grommets are soft and flexible, but stiff enough to remain well seated once installed and they appear durable. It's a nice assortment and I expect I'll find uses for many of the different sizes in the future rather than resorting to redneck engineering. My mass airflow sensor is now seated properly and I expect that new grommet will last just as long as the original.So, we have a large assortment of grommets many of which you may never use, but when you do need one it's certainly nice to go fishing in this assortment rather than having to go to the store or hunt online for what you need and then have to wait for it and hope it's the correct size.This is a nice assortment of quality grommets at a good price. I expect I'll find lots of uses for this assortment in the years to come.

Excellent O-ring assortment that made it possible to seal 2 leaks in the auto air-conditioning system and repair a leaking floor jack. A popular Amazon review states that these O-rings are for "faucets only", which is NOT TRUE ! There were no such markings on the compartmented plastic box OR the packaging that I received. They are made of HNBR, which is the CORRECT material for auto air conditioners, and are NOT recommended for faucets or water valves. The large assortment provides a good selection of sizes to fit your auto air conditioner, and will work perfectly for that task. Be SURE to select the correct SIZE for your application, and your vehicle's air conditioner will hold it's charge and keep you cool, even in the hot Southwestern desert climate.

These are great O-rings and come exactly as described. I was appreciative that the plastic container holds the O-rings nicely and has a label with the sizes on the container for easy and convenient use and storage.

Great o rings. Assorted in a convenient case and seem to be good manufacturing quality. I like the size assortment as it fits my needs (rebuilding paintball guns). Price was reasonable and quality is good. The reason I only gave four stars vs five was because the orings are very soft and the pictures of the orings on the top of the inside of the case show an angled oring instead of a flat one. This makes it annoying when I try to put an oring back in the case and want to quickly compare it to the picture on the chart to know what tray to put it back in. Not a big deal but something that could be improved upon. Overall, I would buy these again and recommend them to a friend!

It's a good idea to get these so you have some orings of different sizes on hand if you are working on your vehicle. Also the green color makes them easy to find if you happen to drop one
