OK....I recently switched from CO2 to HPA. I have a Crossfire 68/3K.
When I put the tank on, everything seems fine...threads on nice and
easy. But at the end it the day that thing is a ***** to unscrew!
Anybody else have this kind of problem? It's not like I'm a big wimp
or anything, but I practically have to put the thing in a vice to get
it off! What's up with that?

I know there was some discussion before about NOT mixing oil and HPA,
but could I just but some lube on the tank threads? Would that be
dangerous?

Any help would be appreciated!

Check that you don't have a piece of an old o-ring stock in the threads.
You should oil the tank threads and o-ring, just don't put oil in the
fill nipple of a HPA bottle.

AHH...that was it....no oil in the fill nipple...thanks Chris!

The threads are on the unpressurized side of the o-ring, so there's
no high pressure air getting to them. A bit of lubrication on the
threads should be fine. I believe I used a bit of lithium grease
on the threads the last time things were sticking.

So, what exactly is the problem with oil and high pressure air?

Too much,( very little) and it's like a diesel engine, cept you tank will
be the combustion chamber. Guys used to put a drop of oil behind pellets in
air guns, the oil would ignite and the muzzle velocity woul increase;
accuracy unfortunatley went down the tubes.

Doesn't this require a spark?

Perhaps an on/off asa would help you. If the tank screws in just fine then
the pressure holding the tank in place may be what's giving you hard time
unscrewing it. Try an on/off asa and turn off your air source and then
degass your marker. That should do the trick and should screw out as easily
as it screwed in.

Feel free to add a bit of grease to the threads. Otherwise, I'd suggest an
on/off. Or at least screw the tank out until the pin's not depressed, and dry
fire a few shots. It's the 850 PSI pushing back at the tank that's keeping it
on (unless the decompression friction heated it up), opposed to the 300 or so
you get at the end of the day from a Co2 tank.
