The high pressure struts use a valve adapter that screws on and then
you screw in a stem that sticks out of the valve adapter to depress
the schrader valve to fill. Then reverse this process to remove.
Result is NO loss of pressure. I think that ATS, and others, sell
these adapters.
Some of the struts have a built in valve that you turn in with a
wrench to inflate and out to seal.

I'd like to get a tank of N2 to keep around to fill my struts. I assume
the welding supply place that will sell me the tank can sell me a regulator
that will get me into the 300-500psi range (right?). Where can I get
the hose with appropriate (schraeder?) valve for the strut end? Am I
looking for something that will thread on, or does it clamp on like a
bicycle pump? With a clamp-on type, how do you avoid being sprayed with
oil and losing pressure as you disconnect?
