PERMATEX AVIATION FORM-A-GASKET NO.3 SEALANT LIQUID 4 OZ(3H)

When you're assembling an engine or working on a fuel system, getting a good seal on your gaskets and threaded connections is critical. Permatex Aviation Form-A-Gasket No. 3 Sealant is a popular choice for mechanics because it stays pliable even after it cures. This means that when you need to take things apart later, it won't be a struggle to break the seal.

This liquid sealant is designed to work on a wide variety of surfaces, including metal and gasket materials. It's great for sealing flanges, threaded fittings, and any place where a flexible, leak-proof seal is needed. Because it doesn't harden like some other sealants, it makes future maintenance much easier. Just a thin coat is usually all you need to create a reliable seal that can handle fuel, oil, and other common automotive fluids.
