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

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

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

Used it to seal a case together worked great

Used this to seal the surface of my oil pan (no oil pan gasket). The product is very forgiving, was more than enough for one oil pan, and the one to two minute tack time worked out perfectly for me. Managed to finish the pan job before going to bed and with the four hour cure time was ready to go the next morning. I would definitely purchase this product again.

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

You get what you pay for!

sealing mac cases

I bought this on a whim from watching it being used on a repair channel on YouTube. I generally like adding a little bit of gasket material when Im using a standard gasket. While its not for all types of gaskets, I definitely feel it helps and will last me a long time. Ill be again be using it for is to assist the gasket I replace.

Put this stuff on everything. Get the bigger container.

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.
