They compress well and return to shape without cracking, which is essential for sealing performance.SIZES & VARIETY:The kit includes 32 different sizes, clearly labeled by inner diameter, outer diameter, and thickness. Great coverage across standard metric dimensions.

They’re sturdy and helpful for getting into tight spaces without damaging the parts. The picks alone would cost several dollars if bought separately.PACKAGING & ORGANIZATION:Sturdy plastic case with individual compartments for each size. The sizing chart inside the lid is easy to read, and all compartments were accurately sorted—no mixed or missing sizes. The case closes securely and is compact enough to store in a toolbox or on a shelf.VALUE:For under the price of one OEM seal kit, you’re getting over 1,500 O-rings, plus tools. This is an unbeatable value for mechanics, DIYers, or anyone doing regular home maintenance.APPLICATION TIPS:While these are great for oil, water, and air systems, they’re not rated for high-heat applications above 120°C. Not recommended for brake fluid or steam systems.FINAL THOUGHT:An extremely useful, well-built kit with every common metric size you’d need. Affordable, reliable, and includes tools—ideal for professionals and serious DIY users alike.#AmazonFinds #ORingKit #AutomotiveTools #NBRRubber #RubberSeals #FaucetRepair #PressureWasherFix #DIYPlumbing #GarageEssentials #MechanicalRepairs #ValueBuy #ToolboxMustHave

Great kit comes with everything you need and great quality seals

The o-rings are adequate quality, most are good, a few are not usable. I ordered this specifically for the 28x3.1 o-rings. The label on mine showed 28x2.4. I measured them and they were in fact 3.1 cross section thankfully. For the price this is reasonable, but the quality control is certainly lacking.

Worked as expected. Good selection and the added tools were a plus in my opinionI would recommend

These are the best O rings. Some are big O ring and some are small O rings, never find yourself disappointed when looking for the exact O that's finnikey pipe requires. their durable too! They can really take the ware and tare that Orings should tolerate . Super easy to figure out with no mysteries. No hacks nedded, no thread tape for the pipe and no unsatisfied trips to the store for the right O. they are brand news feeling, do not feel used one bit. It's well worth the money to buy them in bulk too bc you never know when you'll find yourself disappointed with out providing the right O ring! Your wife would be pleased to not having to beg you to find the right O ring for her hunny-do project!Get the rings it'll be worth it!

Came quickly. Great selection and are good quality.

I bought a filter for my refrigerator and there were no O-rings installed on it, so instead of tossing it in the garbage (these filters are not cheap) I ordered this kit. Using the old filter I was able to compare the O-ring sizes and got it right on the second try. No problems, no leaks and cost was pennies.

Large selection of o rings for about any application you may need. I needed one for my gas can spout so it wouldn't leak when pouring into mower and a #25 worked just fine.
