Filling with nitrogen

PSI on the low side.
$13 for the gooseneck to fit the schrader valve and $25 to have a long
hi-pressure hose made.

Keep in mind that it a takes high pressure to force the schrader's needle
valve open.

Ok, today I got the nitrogen bottle, it was about $100 for 40 (liters?).
The regulator is high side is 0-4000 psi, low side 0-200 PSI. Is this
enough, or do I need to exchange that, and what pressure is required?
Standard pressure hoses, as I am sure you are aware, are only good
up to 200psi.

Thanks for all the hints.

Seems it takes 200-300 psi. to open the schrader...
What plane you have?

Keep in mind that it a takes high pressure to force the schrader's
needle
valve open.

The needle on the Schrader valve is opened with the center post of the
hose end, not from high-pressure in the hose. The fill adapter depresses
the valve stem.

You have one of those fancy $30 adaptors that the turbine guys use.
Most common for GA lights planes is just the gooseneck by itself.
I started to explain about the tee-post adaptor but left it alone.
I think Aircraft tool supply carries them...

Ok, I'm showing in the $400's to get that high. The regulator I got, a
victor 0871-0044, 5-125 psig is $146.

What I am going to use this for is to fill tires and service the strut
at my powerless tiedown location. The price difference covers that
the strut pump costs:

Besides I assume also having the correct fittings I need for the
scheader valve.

So it seems the way to go is stay with the low pressure system I have
for tires, then use the strut pump to multiply pressure to get that
done, which is a less frequent event.

Have I missed anything?

My regulator says Victor Medalist P250-500

I was thinking about this kit for my struts. The hand pumps are nice
for an emergency fill with air or H if you have a tank sitting around,
but this kit isn't too much more money and stowes nicely away.

Hi,

I am considering purchase of a nitrogen fill system. I don't have power
at my tiedown, and filling the tires with a 12 volt portable compressor
is a pain due to having to park the car near the tire, move to the
other side, etc. I figgured a nice nitrogen tank system would give me
a power free solution and fill the tire with the best possible kind
of gas.

I found a fill system online:

http://www.aircraftspruce.com/catalo...trogenTire.php

My only question is why it says "no struts". That would seem to me
to be one of the best uses of this system, that I can top off my
strut, which is forever going low (on a Cessna). Is there a reason
for this restriction, and is there a system that can do struts?

Thank you.

Scott Moore

A $40 ten gallon air tank is way more than enough for tires.

Agreed. I have a 5 Gallon tank (purchased for about $20 at Kragen) which
I take home to fill using my compressor about once or twice a year. With
no power in the hangar, this little tank works great to top off the
tires. It works well enough that I haven't bothered to keep track, but
I'd guess that I can put 2-5 lbs in all three tires for some 5 to 10
occasions before I'd need to refill the tank.

Nitrogen for tires? Isn't that kindof expensive?

I have a cordless air compressor. Rechargeable. Has a built in light.
Clearly designed for emergency car use. I love it. I think I bought it at
K-Mart and I have no idea how much I paid. I just Googled and saw prices
ranging from $40 to $60. Mine has been pumping away for about 6 years now. I
use it for the airplane, the car, the boat trailer, bicycles, no name it. It
has A/C charger and a cigarette lighter adapter for recharging.
