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

It’s an anaerobic gasket former from loctite; as you can expect, it’s a great product!

Hard to find without ordering on line.

This is usually an excellent product, this particular tube was however much thicker than usual, and impractical for use. I would guess possibly too old, or a bad batch?

if you have a race car you will need this stuff

Used this on a stihl chainsaw to seal the cylinder to the crankcase. Worked flawlessly.

I would use this many more places if it wasn’t so expensive compared to RTV. It is so much cleaner and it seals just as well, if not better. Used it on transmission case and on jet ski pump.

Its the Red Loctite we all know and love. 10/10

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.

Used this product to seal two halves of an aluminium outboard crankcase. Directions said to use primer I did not. I thoroughly cleaned both surfaces with lacquer thinner then used a small paint brush to apply a thin coat to each side making sure to give a little distance near bearings. Then assembled crankcase let set for a couple of days. I was concerned after reading some reviews that the product would not cure properly without primer so I disassembled to check cure before completing assembly. All was fine cleaned again resealed and reassembled let sit for a week before running motor. No leaks ofter running motor multiple times. One tube will do many small engines. Would recommend. set time was not a big rush product cures when air is absent after assembly.

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.
