Out in the sticks and need substitute for Crossman Pell Oil. This will not go in the compression tube but only to lubricate tip of CO2 Cylinder. I read Alphabet org fluid is OK but do not want to harm the seals. Please advise.

Crossman PellOil subsitute for CO2 cylinders
- Thread starter JDR
- Start date
Automatic transmission fluid will not harm CO2 seals…neither Buna-N nor polyurethane. It’s a good choice for this application.

Yes, it's fine for that.
Mixing motorcycle fork oil and 80/90 gear oil 50/50 is another good option.

I've used RWS Chamber Lube on my CO2 cartridges before.

Just FYI, in the first paragraph they make the following statement:
"The valve assemblies in today’s CO2 powered air guns are fitted with silicone seals and O-rings."
I suppose it may be true for Umarex CO2 airguns but it is not true for CO2 airguns in general. And that's a good thing because silicone is a poor choice for CO2 seals. Firstly, silicone is highly permeable to CO2...at least 30x higher than Buna-N or polyurethane. Secondly, for guns having a face seal on the valve for the CO2 cartridge to seal against...that's a bad application for silicone because it is highly susceptible to tearing.

JDR, use 100% silicane oil only. Crossman Pellgun oil is a petroleum product (read the small print). Silicone oil is not the same as silicone rubber or synthetic rubber they have different components in them that make them flexible and susceptible to deterioration. Over time it will deteriorate the guns seals CO2 or not. CO2 gas cannot pernitrate 100% silicone oil, neither can moisture or ultraviolet rays and it will coat the materials in your gun (all of them) and it can be found in any hardware store or on line. Use 100% silicone oil on you gun.

Type-f or dextron. Dextron was the fancy stuff.
What Is It?
What is Pellgun oil? Pellgun oil is a non-detergent oil that is petroleum based with added o-ring and seal conditioners in its formula.
Pretty much what auto trans fluid does
