Silly question but is the difference between green, blue or red loctite?? (apart from the colour)

the red's a little sweeter than the others.

seriously,

Red: permanent threadlock: jesus bolt, and other places you won't plan on servicing regularly.

Blue: temporary-Every metal to metal thread connection. some say it's fine in place of even red--seeing as how red is a real pain to break loose and clean threads of.

Green: sleeve retainer---for non-threaded metal-to-metal interfaces---pinion gears, oneway gears, etc. very difficult to break free without a press.

if it ain't broke, break it.

I never use red. It is pain in the a$$ to break it in case you need to change parts. I would say almost impossible to break it. Blue threadlock is safe.

I mostly use Red, I don't like glitches or parts falling off! It does have a tasty sweet smell.. I prefer the MA kind!

I use red too. No need to ramp down hard on the bolts, just a slight firm snug and be done with it. Just use a small butane torch for the set screws to soften it

Cuda is correct...

I've also heard the green refered to as "gap filler" formula as well.(not by loctite... just around the shop I worked in) It works good on threaded connections that you maybe had to drill a broken bolt out of and the threads are a little buggered. But thats automotive sized bolts. I would say its only good for sleeve retainer purposes on the helis.

red loctite isn't hard to get apart with a little heat. Something like 400 degrees the stuff burns right off. Soldering iron or small pencil torch works well.

Hi guys

About a year ago (or longer) Dr Ben posted a loctite page. Do a search, it was good. I printed it out and put it in with my heli manuals....

I read that the red one is for temperature applications ( engine and exausts ).

Green is the strongest.

I use blue ( all metal ) and red ( exaust screws ) and never had a problem with them.

Keep it up...literally

Hi guys

I went and found that loctite post by Dr.Ben.....here goes:

271, Red: High strength threadlocker for larger diameter hardware.

262, Red: High strength threadlocker for for hardware smaller than that which uses 271 (more like heli parts). Either does a good job for our stuff, however. I see 271 most commonly in auto parts stores.

609, Green: Retaining compound, high strength, for mounting slip fit bearings to shafts. An appropriate product for tail boxes.

603, Green: Retaining compound, high strength, similar to 609 but good where the parts may be a little oily. Good for mounting oilite bushings in housings, BTW.

640: Green: Retaining compound, high strength. Similar to 609 and 603. Lacks the oil tolerance of 603. I use it where I might have trouble with adjacent bearing contamination with the product, such as start shaft bearing blocks, since it has a little greater viscosity than 603.

638, Green, rather thick: Ultra strong retaining compound for assemblies with a marked amount of slop in the fit, min 0.004". Don't try to use this stuff for our normal bearings on healthy shafts. It sets almost immediately in the tight gap, and you'll never have the chance to get the bearing into place.

290, Green: Wicking product for thread locking AFTER assembly. Medium strength, much stronger than 242 blue in my experience. Not the correct choice per loctite for bearing mounting.

242, 243 Blue: Classic medium strength threadlocker for most of our threadlocking applications. 243 is the oil tolerant version.

222MS, Purple: Low strength threadlocker for small diameter or otherwise delicate fasteners.

Bottom line:
NEVER choose a loctite product by color alone.

You can build a really good model with 242 for thread locking parts you'll need to remove, 271/262 for screws you really don't want to ever move on their own, and 609/603 for fixturing bearings to shafts. 290 is great for set screws which needed to be tweaked for ideal postition of the part on a shaft (like a bevel gear) and which you don't want to have to go back and remove the screw to apply the loctite.

I know guys use other products for these tasks, but these recs are based on the specs and technical data sheets published by Loctite.

Thanks Dr.Ben.....I hope you dont mind me passing on the good info

Loctite is the generic term we use for thread locking compound, although many other manufacturers make such a substance.

The colours are NOT the same for all manufacturers, so it always pays to check that you have the correct grade required. Blue is usually the lightest but the red and green can be different.

I agree with PeeFor. Don't just go by color. If you go to the Loctite web site there are more types than you can shake a stick at. I use the green 294 wicking grade, good on 1/4 and below fasteners, on everything. Even the fan. The key to using loctite and thread lockers is to clean the surfaces first. All my fans have been treated with 294 and in 3 years have never had one come off.

Great thread and info guys. Very much appreciated.
I never new there was so much variants even between the different colours of loctite. Great reading. I've printed this all out and now its sitting in the heli workshop.

I use 243

http://www.loctite.com/int_henkel/l...id=241&layout=3

On every thing, I seen what the red stuff does, the green sucks.
Effective on all types of metal threaded fasteners. Prevents loosening on vibrating parts such as pumps, motor mounting bolts, gear boxes or presses. Recommended for use where disassembly with hand tools is required for servicing and where parts are contaminated with oil.
Makes sense
