[Guide] Loctite Applications

[BlackVCG]

The following is a list of loctite products and the applications for which they should be used.

271 (Red): High-Strength (permanent) - This loctite is to only be used on screws you don't ever plan on removing again. It requires 500F heat to melt it so the part can come loose, so use this product with caution.

Typical Applications: Set screws plugging holes; Vertical ASA bolt; Anything that is going together and never coming apart again

242 (Blue): Removable-Strength - This loctite is best used on any threaded part that you need to keep from coming loose, but want to remove it on occasion to clean it or install another component. It is removable with mechanical force.

Typical Applications: Drop-Forward set screws; other set screws that need to be removed

290 (Green): Wicking grade - This is used for parts that are pre-assembled and need to be locked in place.

Typical Applications: Trigger rod; Solenoid plunger rod


Thread Sealants:

545 (Purple): This is a thread sealant, not a thread-locker like the above products. This is to be used on airline fittings that need a sealant to keep them from leaking. Allow 24hrs to fully cure.

Typical Applications: Air line fittings

592 PST (White Paste): This is the best substitute for teflon tape. It's a paste with teflon that does not dry and is better than teflon tape because it won't tear and send strands of tape into your gun and possibly cause problems.

Typical Applications: Air line fittings

How about rescources, like where to buy the stuff, because I've had a tough time finding the rarer blends locally.

And a related question: does anyone know how strong the green sleeve retainer compound is? Like if
I use it on a bearing that's a nice slip fit will it glue the bearing in place like, really good?

I am a huge fan of 545 for air fittings. Just one tiny bead around the bottom of the fitting has effectively sealed every fitting I've ever used it on. Just remember to let it cure for 24 hours before running air through it (so it's not the best for emergency repairs).

592 isn't really rated for paintball pressures... it's max is supposedly around 300psi.

just so u guys kno...if u need to remove something that has been red loctited its not impossible....

i bought a maxflo and it came with a steel hose quick disconnect instead of a macro fitting...no problem except it was in with red loctite...a small blowtorch, monkey wrench, vice, and 5 min and a little bit of teufelhunden's craziness and we had it off no problem

I'd suggest never using red loctite on a gun, even on parts that will NEVER EVER EVER be taken apart.

1: blue does a damn fine job, and won't work loose on it's own
2: even if you know for a god-blessed fact that you will NEVER take a part off, you'll take it off one day.

This Rocks!

THANK YOU!!

I have been playing paintball for over 10 years, some time ago I had a little cheat sheet but had forgot it all as it was lost about 5 years ago and I have been needing this kind of info for some time now!

THANK YOU!

I have a questions about loctite 243. Its labled as "medium strength/oil resistant". This is all I could find in my little town while I Was trying to find some 242. Is this going to cause any problems with my marker, or will it be fine, or even better than 242? Thanks in advance

After buying a freak barrel that was RED Locktited together! I have come to the conclusion that an IQ test should be given before it is sold to the public.

i cant see the loctite on the screws but what color is it and how hot do i need to heat to get my screws off the front frame bracket of my rt ule custom?
