Great O Ring Assortment
I liked the fact that it was a variety pack, and it had the size I needed, at a great price. I needed a couple of small O rings for the hose and wand on my pressure washer, and this product work great. The O rings appear to be not very firm but durable, they are a made of 70 durometer Butna rubber, and not as firm as the (90 durometer nitrile rubber). So far no leaks, and would recommend.

Great set for a good price
I needed to fix my 20 year old power washer. My father in law bought if for me from some discount store years ago and it’s some kind of knock off so I couldn’t find any specs for it. Bought this set and 5 o-rings later I’m in business again!

Great Assortment. Thickness Info.
This kit has a great assortment of O-rings of different Dash. I need one for a leaking faucet in my kitchen, but soon found out the old o-ring I was replacing was thiner than the one I got out of this set. I know it's my fault for not measuring the old one's thickness, but I wish this kit would have more info about each piece's thickness. Anyway, I ended up using the o-ring anyway, because I didn't have the time to be looking for the right one anymore, the faucet head won't go in all the way into its base, but it's not leaking anymore . Point is, I will give you the thickness of each ring provided in this kit. I used a caliper and measured each by inch fractions, if you need me to do mm or whole inches, please let me know. I will list the Dash numbers and since most are the same thickness, I will simply place a - between size ranges. Between Dash number 325 - 327 the thickness is 13/64 of an inch. Between Dash number 210 - 222 the thickness is 9/64 of an inch Between Dash number 110 - 116 the thickness is 3/32 of an inch Between Dash number 006 - 012 the thickness is 1/16 of an inch.` Well, that's it for the thickness. As I said, the kit is great for an assortment of diameters, but it may not be that great for those looking for thinner o-rings. I hope this helps.
