These are pretty simple parts, but they do a crucial job. Essentially, they create a watertight and airtight seal. They’re usually made of a soft metal or a composite material, and they get crushed slightly when you tighten a bolt or a fitting. That crush is what creates the seal, preventing fluids or gases from leaking out. They distribute the clamping force evenly, so you don’t damage the surfaces they’re sealing against. You’ll find these things all over a vehicle. They’re common around things like oil pans, valve covers, brake calipers, fuel lines, and anywhere else you have a bolted joint that needs to prevent leaks. Different areas will use slightly different sizes and materials depending on the fluid being sealed and the amount of pressure. Sometimes they’re single – use, meaning you really should replace them every time you remove the fitting. You’ll notice if one fails because you’ll start seeing drips or, in some cases, hearing a hissing sound if it’s a gas leak. These little washers might not seem like much, but they’re absolutely essential for keeping everything running smoothly and preventing damage. Leaks can lead to all sorts of problems – low oil levels, overheating, fuel inefficiency, even engine failure. Replacing a seal washer is a cheap and easy preventative measure. You can find a wide selection of them at places like Fixparts Online, and it's usually a good idea to have a variety of sizes on hand. It’s far easier to replace a ten – cent washer than to fix a major leak or engine damage. Durability you can trust: Seal Washer (MPN 5C3827147) has a 12-month warranty!
