I know red is permanent (so to speak). What about blue and green? How difficult are they to remove? When to use which one? Are there any other types? Thanks.

Michael

I don't know about the green. But I do use the blue Locktite on anything that I don't want to come undone in flight. I've never had a problem with it. And yes, you are right about the red locktite, don't put it on anything that you ever want to come undone later down the road. It is very permenant!!!

Blue is a thread-locker for nuts and bolts that you don't want to fall off, but can
be removed easily. Red is a more permanent application for cylinder studs and
the like....things that are not normally removed, except in the case of severe
damage....like engine case replacement.

Green Lock-Tite is used for replacement bearings where the old bearing has spun
in the case, and the new one is too loose. It is the thickest of the bunch for
obvious reasons.

Lock-Tite turns to a plastic when it hardens. It hardens in the absence of air.
Any of these products can be softened with some heat, for removal.

All three are commonly used in motorcycle and small gas engine repair.

I think it's like this:

Blue: removable
Red: Permanent
Green: Very permanent

hello
test 005
hit the nail on the head!

None of them are permanent....a bit of heat from a cheap propane torch,
they loosen up. Remember, they are plastic. Heat plastic and see what happens.

There is more to it than just colors...

There is red = permanant (think 272 ????)
but ther is also red = high temp and permanent I think 271 (someone please check this if you actually use it)
Blue = removeable
Green = wicking and removable ( flows into the cracks of a bolt that is already installed)
Green= engine sleve retainer ( Probably never going to get it out designed for high temp and permanant)

I know there is a lot more to it than that, but those are what I remember

Always use numbers not colors when buying... I am sure a call to Loc Tite will provide you with more information than is here and will most likely be 100% correct

You may wish to visit the Loctite website for their product information directly.

Thanks. Web-site pretty interesting. Tremendous number of agents.

MSP - I just noticed your location. I moved from Farmington Hills this past spring and was a member of Ribcrackers. Which club do you belong to? Though I'm glad we moved - we're on a lake and therefore I fly from it during the summer and am able to now fly from it with skis due to the colder than normal fall we've had - there's one thing I really miss since I moved. That's Joe's Hobby Shop on Grand River. My closest hobby shop is in Ft. Wayne - about an hour away, while Joe's was about 10 mintes! - and not nearly as complete a shop as Mark has there at Joe's. Be grateful for Joe's being there and don't hesitate to use them, even if the cost from Tower seems lower, many times Dave Shiavolin (sp?) will order the same thing for you and meet the price from Tower.

On occasion I will use the blue stuff but I've found that the purple for the most
part does everything I need it to do. It keeps things in place and requires less torque to
break free when you want to dis-assemble. If your using Loctite near or around plastics
you may want to consider using Loctite #425.

I also suggest you visit the Loctite web site.

I fly with PMAC (Pontiac). Joe's is excellent. Dave is the BEST! He always helps me with any problem. I usually bring a new plane in for Dave to look over and help me get the CG correct. The help I get from them more than covers the few dollars more I might pay for some stuff.
