LOCTITE 640 High-Strength Sleeve Retainer, High-Temperature, High-Stength, Anaerobic Adhesive, For Large Diameter Components, Active Metals | Green, 6 ml Tube (PN: 487235)

good stuff

This worked really well to secure my dipstick tube into the engine block.

We have a very busy auto repair shop, recently we had a Chevrolet pick up that had lost the differential carrier bearings. When the bearing race spun it damaged the differential housing, because a used one is $500.00 and a new one was out of the question for this customer, we opted to use Loctite #640 high strenth sleeve retainer repair. It did the job very well and we will use it again if we find the need.

I used this to sleeve a steel tube, and then turn it down. It held on like weld. Just follow the directions.

Its Loctite, it makes things get stuck. Perfect!

Only brand I trust is loctite

Not something you can find at local home improvement or hardware store. I needed this for an RC helicopter pinion gear gluing to the motor shaft. The torque was enough to break high strength red Loctite 271, but this green 640 stuff hasnt broken yet.

When you need metal locking adhesive this is it.

Needed this to repair valve guides in a B&S vtwin motor and so far it is working fantastic.

It is the standard for a reason
