KOOTANS 1200Pcs Nitrile Rubber O Ring Kit 24 Sizes O Rings Assortment Kit Set Sealing Washer NBR Metric o-Ring Assortment for Plumbing, Gas, Automotive and Faucet Repair, Resist Oil and Heat O-Rings

Exactly what i needed!! Great variety of rings.

A lot of good o rings not much more to say.

Needed brings that would stand against diesel fuel. So far so good.

Nice o'rings perfect sizes

I needed a replacement rubber o-ring for my mini kerosene lighter. The original one dry rotted and fell apart so can’t have fluid oozing out so needed a replacement BUT, what size? LOL! After going back and forth looking at variety of options and still not knowing what size I need, I decided to go with this one and I’m glad I did. First, packaging was good. Container was rapped in bubble wrap securely. Everything inside the container was in place with zero loose ones drifting into other size slots. All the smaller o-rings starting with the 12x1.5 are in individual bags. The included tools came in handy and assisted me with getting the lil rascal on the lighter. Best part, I’ll probably won’t need to order another o-ring in my lifetime lol. I’m going to keep them in my cool dry basement along along with all my other tools and cool gadgets so they don’t develop dry rot. I have a lot of gadgets that use o-rings so this will be useful. Oh, I used the 11x1.5 size to fix my lighter issue in case you were wondering lol

good quality product

I thought that with 24 sizes I would be able to replace most worn rings at home. The first time I needed to do so, I discovered that yes, this kit had the diameter I needed, but the thickness was not right and with O rings, the thickness is probably even more important. If, like me, you are buying this kit to cover your possible or eventual needs, think again. To cover all sizes and thicknesses you may need, I cannot begin to guess how large a kit you will need.

I just received this O ring set and since I am very impressed I thought I'd leave a review. I cannot of course speak for the durability of the O rings over time because time has not passed, but they do appear to be of uniformly high quality.The set seems pretty comprehensive with everything I should need for decades. The 4 piece hook set included is of higher quality than similar hook sets I own! The case is also higher in quality than most organizer cases that are included with parts sets.It's a very nice touch that the smallest O rings come in bags. If the set gets spilled those bags will be a godsend.At currently $21 for the 1225 piece set I think the value is good too.I spot checked some compartments and the counts were correct. Thanks to the manufacturer for getting everything right with this set!
