Sealed tighter than a hangar door in a hurricane!” Had my trusty A&P buddy install this gasket on the ol’ magneto, and let me tell you — it’s holding better than my last diet plan. No more little oil leaks making my engine look like it’s crying aviation-grade tears. The mechanic said, “This thing fits so well it’s practically got its own airworthiness certificate.” We both chuckled, high-fived with safety wire pliers, and called it a job well done. Since then, not a drop outta place. Plane starts up smoother than a flight instructor’s sales pitch for an instrument rating. If your magneto’s been sweating like a student pilot on their first checkride, do yourself a favor and grab this gasket. Your engine — and your dry hangar floor — will thank you.

It’s just a gasket. But it’s on the shelf with quick dispatch.

I ordered these to use with installation of overhauled magnetos I ordered. The magnetos came with gaskets, but I liked the appearance and thickness of these better, so used these instead.

This is the correct gasket to us with Slick 4370/4373 magnetos on a Lycoming O-360-A1A. 3.5475 OD X 3 ID

If you are buying the mags, you most likely need these gaskets. For the price of the mag, they should be included with the purchase.
