Loctite 518 Gasket Sealant 6 mL Tube, Red (2096062) (Packaging may Vary)

Hard to find without ordering on line.

Always use on my header flanges and any v band connection that sees lots of heat

Great product, works very well.

Use it in VW engine building, great.

Worked great on an outboard crankcase

We rebuilt a lot of gearboxes were the cases are bolted together without a gasket; a metal-to-metal joint. This sealant is perfect for this and never lets us down. Very easy to use and will clean off with solvents and a rag if you need to remove it. It is a bit soft setting, so it doesnt dry out and crack. Excess that gets squeezed out of the joint will not separate and wind around inside the gearbox like silicone.

What the heck... Why not? 5 stars for warmth. No issues with the product, sealed properly upon delivery and worked like it should have. Good stuff.

Used this stuff for years. Only dries when its compressed between 2 surfaces. Forms very thin seal in minutes. Resistant to gas and oil. Would put it on toast if it were edible!

Used it to seal a case together worked great

Amazon REALLY needs to include the fact that you ALSO NEED TO ORDER the activator separately. This requires the spray activator on NON-Active metals like aluminum.
