No, not all lubricants are the same. This is definatly true for silicone sprays.

No, not all of them are "safe" for airsoft use.

NO WD-40, liquid wrench, PB Blaster, etc... or real steel gun products! (thanks BroodRed, I forgot this one)


What do you need to know, or do about this. - Well, read below.


Silicone spray lube: Generally any should work.....
Provided - it does not contain any: petroleum distilates, petroleum by-products, Hydro-Carbons, or any harsh petroleum based products,
Such as: Hexane, Heptane, Toluene, Xylene, Ethelene, Xylol, Toluol, Naptha, benzene or any other flamable substance! (aside from the propellents listed below).

If it is using ISO-Butane, or propane "as a propellent", that is fine.




Silicone Grease: (paste, non aerosol, whatever.. - This also goes double for ANY other type of grease.)
Again, you want a grease without the same chemicals listed.
Does not contain any: petroleum distilates, petroleum by-products, Hydro-Carbons, or any harsh petroleum based products,
Such as: Hexane, Heptane, Toluene, Xylene, Ethelene, Xylol, Toluol, Naptha, benzene or any other flamable substance!



Recomended Lubes and Greases:

Permatex dielectric grease. From autozone it's 100% silicone, and 5.99 a tube. Great for cylinder/airseal components. (Thanks GoLgo 13)
Permatex white lithium grease. Again from autozone in a tube for $2.99, works great for gears.
STTi Silicone Spray Lube. From your local Airsoft shop, or even online, Amazon carries it too!

Personally I Swear by "Team Associated - Green Slime". It is meant as a silicone based shock lube, for silicone oil filled shocks. This stuff is $2.50 a tube available at most hobby stores, or online. I use it for EVERYTHING. Gears, O-Rings, Piston, Piston head.. Etc. I have found there is NO problems in doing so. I tore down my CA M15A4 <AT> 1100 rounds, to upgrade it's spring, and piston head. I used this grease. That was over 35,000 rounds ago. All the gun has ever seen is a teardown, cleaning, and re-lube.
Tower Hobbies $2.39 a tube. or RC Planet $2.35 a tube.






Something for everyone to think about... CRC's 808 "Pure Silicone Spray Lube" is:....
30-60% Liquified Petrolem Gas (LPG),
30-60% NAPTHA, You should know this is what "ronsonol" lighter fluid is made of.
10-30% Silicone. WTF.... Pure silicone spray my censored2.gif ...

What this means to you is: The petroleum byproducts, distilates, etc... They are used in the manufacture process of many plastics and rubbers. While this is not any news of shock value. What do you think will happen when you expose an item (hopup rubber, etc.) to the same chemicals used to manufacture it. Yep, you got it. It's going to change it! And not in a good way either.


While I am not completely against the use of Lithium Grease (specifically the thinner "White Lithium") variety. I believe it needs to be pointed out that it IS hygroscopic. Meaning it WILL absorb water. The bad part of this is, in doing so, the oil used to blend and thin it down gets displaced. This allows the lithium grease to thicken into a very thick paste and basically cause binding.

Also, Silicone lubricants are based off of "weight" (aka thickness). You will find everything from "0 weight" spray silicone, to upwards of 45wt shock oil. -=- I do NOT recommend using Silicone OIL's (be it spray, or drip bottle) varieties in the gearbox. Only Silicone Grease!

DuPont Teflon Silicone Lubricant test.

2) Analysis of Chemical compounds
3) Burn tests
4) Conclusion


1 Contents

Petroleum Distillates CAS 64742-89-8 Use- Solvent
These are very volatile and flammable, this means in theory that they evaporate and ignite easily

Teflon flourpolymer. This is like Teflon coating but the DuPont special formula, it should be good lubricant for any application as it one of the least reactive things on this planet with extremely low friction…
http://en.wikipedia....afluoroethylene

Acetone CAS 67-64-1 Extremely volatile with boiling point at 56 C 133F at 1 atm means it easily evaporates but can cause damage to plastics and rubber on contact even though unlikely. In our case its use is to dilute the silicon so it sprays out.
MSDAhttp://www.jtbaker.com/msds/englishhtml/a0446.htm

Aliphatic hydrocarbon CAS 64742-47-8 wide range of boiling points and can be volatile and non volatile, it can be very reactive and not reactive at all. This poses an interesting question of it being dangerous to our airsoft guns or not. The chances of this being a non volatile substance and at the same time being reactive and degrading are very low and I would bet it is most likely something like methane which can occur in a propane butane environment.
Wiki http://en.wikipedia....phatic_compound



2 Analysis of information

1) Everything that’s not silicone or Teflon lubricants should easly evaporate or burn off.
2) Concentration of the pure lubricant (silicon Teflon solution) should be easily achieved by boiling to about 150 degrees C


3 My burn tests

Setup Aluminum can for a test surface above mentioned silicon lubricant and a bic lighter

Burning test Of DuPont Silicon lubricant

Right after
The solution easily ignited showing the presence of alcohol and acetone the solution burned until a thick oil substance left the composition is assume to be silicon oil Teflon and solvent non reactive hydrocarbon chains which would be the cause of the liquid substance. And at most 1% of any reactive volatile substances (alcohol acetone etc)
Video.


30 min after
The solution didn’t ignite and was already as previously mentioned thick oil substance when another spray of silicon oil followed the two layers didn’t inter mix and a thick and thinned out liquid were present. The liquid easily ignited as before.
Video.


Test of gun oil Silicon Spray For air gun & Model Gun Siries purchased at airsoft Gi
http://www.airsoftgi...roducts_id=3301

Airsoft oil test.
Right after spraying.
Ignited left an oily substance behind.
Video

http://www.youtube.com/watch?v=husqVqtHHk8

4) Analysis of results

The burn test showed that all of the volatile substances easly ignite and are present in high concentration at spray signifying that the spray should NOT be used directly on only ruber/plastic part as they might get damaged, this also means spraying this lube into gas mags is not a good idea since non of the volatile hydro carbons will evaporate and will come out when you shoot possibly damaging your gun.
This test also showed that the volatile and reactive hydro carbons are easly removed through evaporation or burning off. Evaporation being the best solution.

What all this means?
Off the shelf silicon lubricants that are spray based will ALWAYS contain some thought of solvent, and in most cases they are reactive and volatile. What my tests so far showed is that most of the volatile and reactive hydro carbons and alcohols are removable, but this doesn’t mean that the final solution is pure silicone oil and still can possibly react with plastics and rubber.

I’m going use this oil to lubricate my WE 1911 and possibly cylinder in my VSS to see how well it works, and in name of science, but only after proper evaporation procedure.

Does this mean you should use it?
Its up to you, you saw the normal Pure silicon oil ignite and Dupont oil ignite what does it mean to you?
It should be noted that chemical reactions are complex and its all at your own risk.

Any concerns post here, I am going to update this with More tests hopefuly a boiling point of both oil, and IR spectra, but it depends on my free time.

I basically do not agree with "average airsofters", using "silicone shock oil"...

Mainly because:
People use heavy weights (0 weight is the best choice),
Tend to forget about it and not clean it up.
Tend to over apply it.

Again with proper maint jobs, this is really a non-issue. I actually use Team Associated 0 weight myself, but very sparingly.

This absolutely needs to be pinned. Several times a month, people post topics like, "omgz what lube should I uze?!" or, "airsoft silicone oil is expensive, can I use (insert 100% silicone oil brand here)?"

Oh, and NO WD-40 or real steel gun greases. I know we all know not to use it, but newer players do not.

Read the ingredients and THEN decide for yourself.

As I have posted in a different thread. They generally will not cause instantanious failure. They will generally cause random delayed failure for "odd" reasons.

Hey umm I know it says don't use lube with petroleum distilates adn stuff but ive heard that what those do is damage rubber hop ups, but the stuff I found in my basement has petroleum distilates but says its safe for rubber

are there still other things that could be damaged by these petroleum by products?

I use a teflon impregnated PTFE grease lubricant that is meant for aluminum paintball internals and is safe on o ring rubber but it works for me, for pretty much everything from cylinders and piston heads to gears and screw threads works great, ive tested it on a 550 fps gun and high 30+ rof setups and it works great.
I do AEG gearbox work modifications/etc- good prices contact me :), shimming wiring etc.

You can check the manufacturers site for an "MSDS", which will list all the ingredients. If anything in there matches what I listed above, find something else.

IIRC, KrYpTiK on here, uses that stuff, and swears by it though.

Don't use silicone oil. It won't stick to anything. And you DON'T need to lube your barrel or BB's.

I haven't lubed my barrel OR BB's - EVER. I do, over use the silicone lube one the FIRST pass when cleaning my barrel. So as the hopup bucking can get some on it. I then do 2-3 more passes (until the clothes start to look clean)..

I have been using Super Lube Grease w/ Syncolon (PTFE) for quite a number of years and it works great! I use it for lubing the gears, cylinder (very thin film), o-rings and the outside surface of the hop bucking to keep it from drying up.

I used to spray silicone lubricant inside the barrel but it doesn't do the barrel any good. It produces a thin film which makes it tacky (in a small way) and it attracts dust particles. What I do to clean my barrel is to use a degreaser (easily removes bb residue) with some clean cotton strips until all the residue is removed. I get better results when doing this. Hope this helps... a-salute.gif



All Shredder's Concave Spacer (SCS) users and those interested are entitled to ask me questions regarding proper installation and accuracy issues.

Permatex white lithium grease. Again from autozone in a tube for $2.99, works great for gears.


So I've finally convinced myself to open up a non-lpeg gearbox. I've always been worried about screwing up my high-end gun or something.
But first I wanted to make sure I had MOST of the materials.

So I walked into Advance Auto Parts today and asked the lady at the counter where both of these items were. She immediately led me over to the grease section (first time I've been in the store so I had no idea where to go) and found both of them for me.
I paid about $9 with tax, so about $4 or so a tube.
+1 for the greases
+1 for Advance Auto Parts a-thumbsup.gif


I'm glad I found this guide because you can pay $15 online for just gear grease (on ASGI at least...) and another $15 on piston and other greases.
The point is, I saved a ton of money by buying the Permatex grease locally, and not buying brand-name greases such as CA or guarder. And by doing my own GB work, I'll save from those labor fees and whatnot.


I figured I'd put that in to show some other users how easy and efficient it is to use alternatives to brand-name stuff. Doing a tad of research will go a long way. a-thumbsup.gif

Well thankfully the plastics in the gear box are pretty resilient to short term contact. I would say with a good cleaning (with again, a NON hydro-carbon based cleaning solution) would do good to get most of the harmful gunk out of there.

thanks. and one last quick question.
are piston head o-rings made of rubber or silicon, because if its made of silicon, you can put petroleum based grease on it.
just curious, not that I would do it.

And also, I already wiped out the petroleum grease in my friend's gearbox with a towel, and relubed with proper grease.

I just installed a new bucking and nub on my rifle, while I was out today I swung by Pep Boys to take a look at their lubricants. I tried looking for something that said 100% silicone, but the closest thing I could find was Pyroil Multi-Purpose Silicone Lubricant. It says its safe for rubber gaskets, but the ingredients listed are Heptane, Carbon Dioxide, and Dimethyl Polysiloxane.....and of course the OP said not to use stuff with Heptane. Im new to this stuff, so why does the can say safe for rubber?

I'm going to guess you either put too much on, or got it in a place where it's interfering with the seals somehow. This could mean either sticking together, or not allowing the parts to seal where they should, such as nozzle/hop contact or piston o-ring seals. See if there's excess and clear up the contact points.

Use your better judgment. Your gearbox contains an electrical contact, that produces a spark. I'll bet if you check that can, it says keep away from open flame / sparks.

Alright, I guess no Triflow then. I always thought all canned sprays say that because its pressurized.

but I just sprayed some on the floor and threw a match in it, and damn...erupted in flames....

So this is the correct lube right: http://www.autozone....oductDetail.htm

Back says it contains: Polydimethylsiloxane and Amorphous silica

I have white lithium grease from homedepot and it says petroleum based. (Huge black tube) I've been using it for a while on the gears and I haven't had problem. There is even some that got on the tappet plate and I haven't noticed anything abnormal.

While Lithium Grease works. I personally do not prefer it.

While white lithium grease is not known to be "Hygroscopic", I know for a fact it is not a water displacing lubricant. Now this causes 2 problems.

1: Lithium can thicken, and the oil will leach from it. Leaving the lithium in a very cake like paste.
2: it allows water retention, which can and WILL speed up electrolytic reactions between the various metal differences in the gearbox. (side note: This is why I am STRONGLY against copper shims, on a steel gear shaft, against a steel bushing, in a zinc alloy gearbox - Combinations of metals from different family's create a battery like atmosphere when mixed with certain chemicals, and even the moisture in the air).

White Lithium seems to repel water fairly well in my experience. AZ is incredibly dry though, so moisture isn't an issue.

So are you saying that it can ignite inside the gearbox or what?

Anything that is flammable, can always be ignited. The "flash point" is what is important. As for Lithium Grease, yeah it can be ignited. It would definitely take some doing to get that to happen. But items that are HIGH in content of Hydro Carbons, or other flammable substances will have a warning on the container about open flame or sparks.

I'm not saying it isn't possible, but correct me if I'm wrong, thousands of airsofters use white lithium on their gearboxes (and several people use copper shims) and I have never heard of failure. The sparks are inside the "contact box" and it would it be pretty insane if a spark somehow managed to leap out and ignite the grease.

I'm not really worried about it. If it somehow managed to ignite, the worst that could happen would be the gearbox would be damaged. I doubt the fire would be strong enough to burn through the shell. lol

thanks for the heads up though. I would use alternatives, but being a minor (and not being to obtain a license yet), a job isn't really ideal right now especially since I'm busy with school, so money is tight with me. White lithium is dirt cheap and you get a butt load.
