Regulator/valve for filling struts

Ben,
These parts are available commercially with the adapters for the hose.
An A&P can get them. They have AN/MS numbers. We were issued them where
I work.
Make sure you read the Maintenance manual for your aircraft. Most Small
GA aircraft strut pressures are below 200 PSI. The strut pressures for
our planes (Turbo-props and Regional Jets) range from 500 to 2000 PSI,
depending on the temperature.
The cost may be prohibitive. The tank will cost $80-150 to buy depending
on the size and the regulator could be up to $400. Leasing a tank could
also be an option.

Hope this helps,
Michelle

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?
