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

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.

Worked great on an outboard crankcase

This is used and cures properly when air is not available for curing

All gaskets, by design, are mechanical seals which have limits; temperature, pressure, and time. Loctite is a second line of defense in cases of material defects. Loctite is on every gasket I install.

Great

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.

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

Put this stuff on everything. Get the bigger container.

No info

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.
