Permatex Aviation Form-A-Gasket No. 3 Sealant - 16oz Brown Brush-Top Sealant

For mechanics and DIYers who need reliable sealing performance, this Permatex Aviation Form-A-Gasket is legendary stuff.

This No.

3 sealant comes in a 16-ounce brush-top can, making application easy and mess-free.

It's slow-drying and non-hardening, which means it stays flexible and never cracks or becomes brittle - perfect for applications where you might need disassembly later.

The temperature range is impressive too, from -65°F to 400°F, handling everything from cold winter starts to hot engine operation.

It resists gasoline, oil, and grease, making it ideal for automotive engines, transmissions, and differentials.

But here's the cool part - it's actually approved for aviation use, so you know this is serious, reliable material.

Great for close-fitting machined surfaces, sealing hoses, and reinforcing solid gaskets.

The brush applicator built into the lid means no searching for brushes or making a mess with squeeze tubes.

Whether you're sealing engine covers, oil pans, transmission housings, or any other metal-to-metal surfaces, this form-a-gasket creates a reliable seal that lasts.

It's been trusted by professionals for decades because it simply works.

The brown color makes application visible, so you can see where you've applied it.

Just clean surfaces thoroughly before application, brush on a thin, even coat, and assemble while tacky.

For automotive restoration projects, engine rebuilds, or just maintaining your vehicles, this Permatex sealant delivers professional results that stand up to tough conditions.

Seriously, this is one of those products that belongs in every serious mechanic's toolbox.
