Need a reliable seal? These PATIKIL nitrile rubber O-rings are super handy for all sorts of fixes. The pack comes with 5 identical rings, each measuring 47mm outside diameter, 43mm inside diameter, and 2mm thick (cross-section). They're made from nitrile butadiene rubber (NBR) with a 70A hardness, which means they're tough, flexible, and resist oils, fuels, greases, water, and hydraulic fluids. Perfect for fixing leaky faucets, automotive fuel lines, air systems, pumps, and general plumbing. They work in temps from -4°F to 212°F (-20°C to 100°C) and handle up to 0.3 bar pressure. Just pop them in place - the round cross-section makes sealing easy. Note: they're not great for constant sun or ozone exposure, so keep them indoors or in protected spots. A must-have for your DIY repair kit.
