    • Worked well and the case is handy to have
Style: 270pc O-Ring Kit (HNBR)
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

    • You may not need them all right now, but it's nice to have the assortment when you do need one.
Style: 125pc Rubber Grommet Kit
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. ... show more

    • Great value
Style: 180pc O-Ring Kit (Viton)
Some of the O-rings were in the wrong compartments which is pretty minor, one was split. QC doesn't seem "A" level, but the dimensions and material seem proper, so perhaps "B" level. Definitely a really good value for something that seems adequate.

    • Probably a lifetime supply if I need them
Style: 270pc O-Ring Kit (HNBR)
For the price you get a nice assortment. For my situation I needed some 0-rings for a replacement of a hydroboost on my 05 Tahoe lines. The old orings were black rubber, I was able to match up a close fit and so far no leaks. I don't know if in my lifetime I will go through more than just a handful of these but it's nice to know when you need them, you got a bunch! ... show more
