Does thread lock act as an anti-seize?

[atikovi]

I don't want bolts to loosen, but I don't want them rusted together either if I do have to remove them. Does thread lock act as an anti-seize? I thought I saw Loctite or Permatex come out with something that combined the two, years ago but don't see it now.

A lot of mountain bike guys use Loctite to protect threads from corrosion...Especially when metals are dissimilar.

Come to find out, Loctite also works as a thread sealant. I used to have to put Permatex 2B on some of the lower intake manifold bolts that were letting oil pressure spiral up the threads and out the top of the manifold. When I finally replaced the intake manifold gaskets, I installed the manifold bolts with blue Loctite. To my amazement, no oil leaks spiraling up through the bolt threads.

That reminds me...
I have 3 Small Block Chevys that get those mysterious oil puddles below the carburetors, mostly on the passenger side.

I use the blue on automotive A/C lines to help prevent corrosion and seizure.

Looks like Loctite Blue would work (mostly) as both:

I use it on brake parts for the same reason.

Orange is the new blue... can be broken with tools but strong like red.

Loctite makes a Purple which is very low strength.

And, yes, it prevents corrosion where the threads meets since the water is locked tight out of the interface.

If you are doing something weird like using dissimilar metal fasteners then each contact area will act like a tiny battery, generating corrosion and/or "welding" depending on the electrical generation of the two metals. There are charts posted on das internut showing this for various metals.

Build up wheels, drip in purple located down spokes to the *******. My secret

This is what green loctite is for

Green as well. Or the CA blue stuff

Loctite 243 Lock & Seal

 

[JackOfDiamonds]

Please don't go by the colors! LOCTITE makes at least 3 totally different green loctites for example. There are also multiple blue and yellow. The medium-strength blue thread lock is 242 or 243.

Why put the blue Loctite in a red tube? It used to be in a blue tube.

I believe that's permatex

Pretty much any thread locker will also prevent rust on the threads.

What's the application/situation?

clearly it's not. lol

 

[SuzukiGS750EZ]

Blue tube, was thinking that's what he was thinking of

 

[JR 42]

I believe that's permatex

The last 3-4 small tubes of Loctite blue I've picked up have all looked like this. I have no idea why they don't make the whole damn tube blue- maybe Permatex trademarked it or something. At least it says "blue," in blue, on a red package...

 

[Mike Folks]

You get into the RED Loctites,then heat is required for dis-assembly,depending on the spec,500F or more,sometimes..

Driveshaft bolts.

before reading further I believe so,acts as a sealer and thus discourages water and corrosion from getting into the threads if enough is used
would think the weakest possible threadlocker would be best for this (Purple)?

would Plumber's Teflon paste be good for this (not a threadlocker)
fluidfilm?

 

[Wakefield]

clearly it's not. lol

I think couple different companies making essentially the same things-Permatex and a German company (Heinkel)?

Heinkel uses the red bottle too lol. We use it at my work. I remember the first time I but loctite brand, I got home and was like ****, I bought red. But then looked closer and saw the tube said blue.

Loctite came out with an orange recently. It breaks with hand tools like blue but has the strength of red.

 

[RedneckWelder]

You really should download the Loctite catalog and check out the product lines they offer for various applications. They offer a ton of stuff the DIY mechanic doesn’t really think of but might find useful

 

[mfewtrail]

Permatex uses blue tubes for all their threadlocker w/ a little sliver of color showing if it's red, green, blue, etc. Not sure anyone uses separate color bottles anymore, but some of them used to...

 

[JRC3]

Hey, don't start arguing about the tube color or whatever...Or else...This thread might get locked.

Wah-Wah-Waahhhh

 

[sweet victory]

That would be too easy...but I don't recall ever getting a Loctite bottle that was anything but red. At least the nozzle is transparent enough so you can see the color of the fluid once the cap is removed.

 

[Ralf11]

I thought Henckel's owned both brands?

 

[Wakefield]

I think the German company owns the Loctite brand name. And another name only used on consumer products like "titetend" But Permatex is another company I think.

 

[davemn]

Permatex was bought by Locktite then sold around the time Locktite was purchased by Henkel. If you look closely, a lot of the Permatex part numbers are similar to the Locktite numbers.
