Found a new source for 100% silicone shock oil for compression chamber and piston seal lubrication. Discovered radio controlled airplane builders also use silicone shock oil and that retailers supporting that hobby carry it. The model airplane enthusiasts often use "Team Losi" brand and they produce what they call 100% silicone shock fluid in viscosities from 10 to 100 in steps of five thru 50, then steps of 10 (60, 70, 80 etc.) It comes in 2oz. bottles and each viscosity is tinted a different color. 20wt. is blue, 25wt. is green 30wt. is clear, 35wt. is orange and so on. Each 2oz. bottle comes with a certificate of viscosity accuracy tolerance of +/- 2%. The retail price in my area is $3.50 per bottle. Bought some today and was surprised to find it's available in such a wide range of viscosities. I'm thinking that a super polish compression chamber surface could use possibly a 20wt. or lighter, rather than a 30wt. that is often recommended on a 400 grit honed surface. Come to think of it, the guys with PCP rifles could find a number of uses for this stuff since petroleum based products should not be used where compressed gases are also involved.

WARNING>>>>BE VERY CAREFUL HERE <<<<
Yes, as has been published on my website as well as here in the library under "All About Lubricants" that it is a good source but keep in mind though that Silicone shock oil is usually used in conjunction with neatsfoot oil and used only for leather seals and should not be used as a compression chamber lube. There is one exception. For the most part, Silicone oil is of little or no use inmostspringer airguns and not recommended.
The compression chamber in a synthetic seal chamber should not be honed with 400 grit. It should be honed with 220 grit stones or wet/dry paper if a homing tool is not available. 400 grit is far to fine to be used but is recommended for leather seals only.
100% Silicone Dielectric Grease or moly pasteshould be used for a synthetic seal during assembly and not Silicone oil.
Never super polish or even polish a compression chamber when a synthetic seal is used. In fact, it should be a cross hatched chamber so as not to be smooth. Never never ever use any oil--- let alonea light weightoil as a lubricant in any compression chamber, especially where a synthetic seal is used.

Mike,have you ever been to hobbytown usa in castleton?

The only thing that I use the Dielectric Grease on is the leather seal's in the B3's. Other then that it sit's on the shelf premixed with neatsoot oil. Ed

Ed,it`s also a good idea when resealing a QB...

Thank's for the info Barry.:) Ed

Barry: I've been to Hobbytown only once, about 10 years ago.
I keep a list of "airgun notes" that I reference often, and I want to thank Bob Werner for his concise Info and words of caution. I did a copy and paste of his post to my notes.
Thanks for the responses guys!

The primary reason for the silicon shock fluid post was to share a source that might be handy for those who wanted it regardless of its application - airgun or other.

thanx for that...I will be getting some soon. In reguards to other applications than inside of an airgun...you can use it on the outside. I have wiped down my rifles/pistols with this stuff and it is excellent for taking fingerprints off, giving a good shine to the bluing, and even using it on some of the wood stocks. A great product to have on your shelves!!!
