I've been droping a drop or oil or two into the ASA threads in order to lubricate my gun for years without a problem. The reason this is ok is because there isn't a direct path to the air tank itself, the air is going through your regulator first. With the nipple it is a direct link to your tank and is the full unregulated 3000 PSI.
ASA=where tank screws into gun
The use of oil with HPA tanks is ONLY dangerous if it's placed on the fill nipple. That's the little thing that sticks out that you plug a hose onto in order to fill the tank. That nipple is a DIRECT line into your HPA tank. In other words that little nipple is recieving all 3000-4000 pounds per square inch of pressure. The thing air passage to the part that screws into your gun on the other hand is an INDIRECT line to your tank because it goes through a regulator.
Your also not pushing air through this regulator in order to fill your tank, air is only coming out. Explosions occur inside the tank when a spark gets inside of it and starts a fire. The resulting burst of pressure is extreamly fast and more than your tank can handle. Thus your tank explodes before counter measures kick in and everyone is angry with you.
Personally I think Co2 tanks are far more dangrous than HPA tanks, they are simply less strong, hold equal pressure, and have killed people in the past.
Ok let the farm kid clear this up a bit. CO2 is contained at 900psi any higher than 1000psi would cause the CO2 to become dry ice or frozen CO2. Air goes much higher in pressure because the molucules resist eachother more than CO2 molucules do(That means that CO2 liquifies and freezes at lower pressures than air).
Good post Im making all of my paintball buddies read it before our next paintball trip.
