We use some small nitrogen tanks that have what I have always called a
"Shrader valve" port on them, used for adjusting the tank pressure.
Tanks are mounted in an ugly spot, I need to attach a semi permanent
flex line to the tank. Same fitting as a tire valve stem (0.305"-32
threads) Checking in mcmaster.com comes up with plenty of "air tank
valves" (page 435) that are the male fittings. I need the female version.
These are fairly high pressure tanks (250 psi) so the fitting needs to
be high quality and heavy duty. The simple clip on fittings found on
12volt portable compressors are just not in the right range. Also, I
prefer that the fitting depress the shrader valve center pin but that is
not absolutely necessary. Something with a valve so you could screw it
one without blowing the charge would be really nice. I can deal with
either a 1/8" NPT outlet (preferred) or a hose barb outlet.
