Moly Lithium Grease

[byhsu]

Just saw this at Walmart.

Says is for ball & roller Bearings, chassis points, bushings, ball joints, U-Joints. Contains Rust and Oxidation inhibitors and extreme pressure additives for long lubrication life.

Would this be good for Lubing a springer rifle?

Only 3% Moly, seems a bit light.

It's not like the typical moly paste found at ARH for example. Moly paste usually have 65-70% molybdenum in its composition, the SuperTech grease only 0.1 to 1% content. Here you can see the MSDS (material safety data sheet): https://www.msdsdigital.com/super-tech-moly-lithium-grease-msds  . Here's a screen shot of the composition:

 I have been using that where regular lithium grease is recommended, such as the piston rods on my shoebox compressor, and the piston seal on a ssp P-17 air pistol, both since new. As far as a piston on a break barrel I'll pass.

Thank You, that looks like a good price. but the page has no button to add to cart, at least not on the my page when I click your link.

Jim Macarri is in the GTA Mall -
Molly is listed under the lubricant section

Don't know about that brand but this msds shows that it's Petroleum distillates, solvent-refined heavy paraffinic and probably susceptible to dieseling.

I know some don't like the old Dino lubes, but they have been tried and trued over the yrs, but they need to be applied correctly just like anything else, if done so u will have yrs of enjoyment from ur air rifle

[Artie]

Two schools of thought (Krytox vs Dino) amongst experienced springer tuners it seems. Krytox (or Ultimox) vs Moly paste is what concerns me. Almost nothing has been discussed in this thread concerning the removal of Krytox in a springer after it has been properly applied.
     I would also like to point out there are more than a few professional tuners who are GTA members that do not advocate using Krytox for various reasons.

[Yogi]

Yes, But that "Super Tech" is not even good Dino stuff!

I had this discussion with OC yrs ago when the new magic Krytox was being use in air rifles, and its effects on metal, I have never used it and probably never will! I do not have enough education on the subject because I have not really looked into the properties of what this type of lubes long term effects maybe for this type of use? Just my personal thinking here but I'm not even interested in this product to tell you the truth, I'm not going to try to reinvent the wheel, I see no need to use anything other then the tried and trued methods that already exist, u may call me stubborn or old school if u want! Krytox my have its use in some applications in air guns, but as another member has mentioned who has used and has Dino and Krytox in use in his rifles, see's no need to convert them all to Krytox, I'm not knocking anyone who wants to use Krytox, its ur rifle, if u think Krytox is of more benefit for ur usage try it! these are my uneducated opinions and we all know about opinions! But if I personally thought Krytox had any major advantage over ole Barny the Dinosaur I would be using it!

[Mark 611]

Also I have tried other lubes in the past, like the Super Tech brands and LUCUS, they will cause u more issues then ur effort to use them! not saying u can't use them in barrel fork areas, but inside the the power plant no! those lubes are not designed for that type of use, incase someone doesn't know? ur air gun power plant works like a Diesel engine, as the piston go's forward it generates heat! lubes not designed to be in there or have a low flash point will detonate or cause bad Dieseling, most of these types of lubes are also to thin and will migrate and get in front of ur piston seal and will Diesel all the time and will burn up ur piston seal in pretty short order!

"burn up ur piston seal in pretty short order"
LOL, like this..........

Artie.- Just a note: Krytox is NOT the same as Ultimox.
I have found Krytox to be hygroscopic (it attracts and retains water), therefore not being as consistent and resistant over extended periods of time. Ultimox, on the other hand is not.

ANY lube is removeable. Even the diffused moly. It just takes time and effort to do it right.

IF you are going from petro-based lubes, you can give a good cleaning with lacquer thinner, and then another with Xylol.

IF you are going from Teflon to Petro, then clean with Thinner and then Acetone.

Of course, take all the needed precautions.

Hummmm.....from the above..........
"THE PERFECT LUBRICANT FOR MANY APPLICATIONS:
EXACTLY LIKE GPL type grease, MicroLubrol™ ULTIMOX 226 is an ultra-high quality PFPE/PTFE grease formulated with fully synthetic highly fluorinated perfluoropolyether oil and micronized polytetrafluoroethylene (PTFE). It is clean white in color and has a National Lubricating Grease Institute (NLGI) #2 light to medium, extremely smooth consistency exactly like other high-performance PFPE/PTFE greases like GPL type greases."

and

"MicroLubrol™ ULTIMOX™ 226 PERFORMS AS WELL AS GPL-226, GPL-205 and GPL-206 for automotive applications. MicroLubrol ULTIMOX 226 is formulated with fully synthetic highly fluorinated perfluoropolyether oil and micronized polytetrafluoroethylene (PTFE) just like GPL-226, GPL-205 and GPL-206 greases. ULTIMOX™ 226 resists the harshest environments and conditions: heat, cold, ice, snow, rain, water washout, cleaners, acids, caustics, steam and automotive chemicals. In addition, the consistency of ULTIMOX™ 226 is National Lubricating Grease Institute (NLGI) #2 which is the SAME as GPL-205 and GPL-206, making ULTIMOX™ 226 a perfect drop-in replacement for GPL-205 and GPL-206 in automotive applications."

Anywhoo....Ultimox seems to simply be a rebranded Krytox GPL226, perhaps licensed by Dupont.

It seems like a cheaper version of Krytox GPL226 and I did use it for a while but preferred the performance of Plain Jane Krytox GPL205 without the "wear & corrosion additive". LOL....I also used Krytox GPL225 a while back. The third digit of the number xx6 denotes the viscosity of the grease and I personally prefer the lighter xx5 version...........


Before switching from Krytox GPL225 to the Plain Jane Krytox GPL 205 I wanted to see how a couple bare nails would react to a soaking of strong salt water. I stripped both nails of any oil, left one nail bare and the other lightly lubed with Krytox GPL205, wrapped both with a paper towel and then soaked the paper towel with the salt water. Here is the result after two days.........


Since I don't wash out my springers with a strong salt water solution I felt that the plain GPL205 was more than adequate at preventing corrosion under atmospheric conditions and after a few years of use I have no issues.

Anywhoo.....if Krytox "attracts moisture" then I don't see how it can be recommended for bearings and such.......

NCed,

I am surprised that the GPL 205 allowed that much rust to develop.

I am new to spring powered air rifle.I used lithium and it killed the seal.I use lithium for my pistols & it's great

LOL....after soaking wet for two days in a strong salt water solution I'm very pleased with the result considering the fact that there was only a thin coating of Krytox to begin with. As mentioned, since I don't wipe the "innerds" of my springers with salt water for two days the test proved (to me) that corrosion with my normal use wasn't an issue.

Ed;

One thing is what lubricants do when under "normal" operating conditions, and another is what happens inside a spring-piston airgun at the temperatures and pressures they reach.

IF YOU want/choose to think that things "stay the same" after being inside a spring-piston compression chamber through several thousand shots, be my guest. Stick to factory stats and specs.

I am relaying here what a group of experienced piston airgun experimenters found after two years of testing (National champions and WFTF Top 3 placer among them).

You do what is best for you.

I will not argue with reality as I find it to be from first hand experiences.

Keep well and shoot straight!
