LOCTITE 518 Automotive Anaerobic Gasket Maker & Flange Sealant - Sensor-Safe, Low Oder, Non-Corrosive - 50 ml, 1 Pack

Used it with gasket on a clutch to front casing on a Honda trx500fe foreman 4x4es. Works great. If a problem arises I will repost the problem. It’s a little pricey but can be used without gasket material. I already had a gasket so I used it in addition to a thin application of loctite 518 sealant on each side of the gasket, it takes a very small amount of 518, so you can get many uses out of one tube.

I use it as a gasket/thread locker, but it kinda sets quick(about 8-10mins) so plan ahead and don’t loiter, otherwise it’s an almost perfect product. A big + is It’s easy to remove the cured product, unlike most Gasket/Thread lockers.

I use this product on jetski motors BUT make sure you buy this specific package. The other version is hard to get the sealant out of the packaging. Thanks for sending the correct one. !!!! 👍🏼

Needed a sealant that handles the higher temperatures inside an engine block and will not degrade. This was recommended to me by 2 different high-performance engine builders that said this stuff works where other brands fail.

Renovated an old 80s outboard and used this on some parts. Seems to be holding up well.

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.

Dose what it's supposed to

Used this to seal the crankshaft of an old Mcculloch Chainsaw. Worked great, saw has no leaks and good compression
