I wasn’t planning on becoming the neighborhood O-ring guy, but after buying this 32-size O-ring assortment kit, here we are. I bought it to fix a leaky connection on my pressure washer, and next thing I know I’m elbows deep in a carburetor, a faucet, and a garden sprayer. This kit is like the Swiss Army knife of rubber seals.The Nitrile rubber is no joke—holds up to oil, gas, and heat like a champ. None of that brittle, disintegrating garbage you find in dollar-bin assortments. These rings are pliable but tough, and the sizes range from “micro UFO” to “might-fit-a-sink-drain.”The hook tools they throw in? Huge bonus. It’s like someone finally realized I don’t have the fingers of a surgeon and gave me the next best thing. Super handy for fishing out old crusty rings or wrestling new ones into tight spots.I’ve already fixed:• A leaking air hose• My truck’s fuel line connection• My cousin’s busted garden sprayer• And yes, the original pressure washer problemAll for less than what the dealership wanted for one factory seal. Go figure.If you do anything remotely mechanical—or just like pretending you know what you’re doing around tools—buy this kit and toss it in your toolbox. You’ll thank yourself the next time something starts dripping and you can say, “I’ve got just the thing for that”

I have an industrial-style faucet... where the two handles are mounted to valves in the wall, and the faucet spout is mounted to the sink (in the center of the double sinks). I recently purchased the house, and noticed that the faucet spout was very hard to move between the two sinks... and shortly began to leak around the collar securing it to the fixture.I removed the collar and one of the o-rings was torn. When I replaced it, the sink was still very stiff... and the new o-rings didn't last long. Within a week, the leak returned and again the o-rings were torn.I found a video online that showed a plumber applying a silicone grease to the o-rings and faucet spout (where it goes into the fixture). I had no idea that those sinks used grease! And clearly, the prior owner of the home didn't either!I looked for "plumber's grease" at my local hardware store to no avail. I found this grease on Amazon and ordered it. It delivered very quickly, and came with a little brush to apply it. It gets the grease into all the grooves, without getting it all over my hands/on my fingersThe faucet spout now turns perfect (smooth), and no more torn o-rings! It has been leak free and a pleasure to use for over two weeks now. This grease did the trick! I'm sure it would work equally well for greasing faucet handles, and other plumbing parts. Great value for the money... solved my problem perfectly.

Was able to DIY a replacement of the AC compressor on my truck when I learned that only 4 bolts hold it to the engine frame and another 2 more bolts secure the low and high pressure connections. What I did not know what the low and high pressure connections have a washer that goes in-between the connection that is found in this kit. After replacing, I decided before performing a full recharge on my system, I would play it safe with new washers. This kit has all the sizes you may ever need but just needed the big red one following the next red one one size smaller. Also needed 2 sets of o-rings that I also tossed a set on amazon and was able to plug back up the connections. Perhaps now entirely necessary but again, mostly wanted to play it safe with fresh seals seeing as truck had original AC compressor for 7 years and half a million miles.

As advertised

Viton. Perfect for higher engine temps. These are "made in China" but appear to be decent quality. Used for replacements on my transmission secondary aux cooler lines. Hope they hold up...

This silicon product works very well for helping to protect and create a seal for gaskets and O rings.

Box very difficult to close once opened.

Seem to be good quality o rings.
