Air is 78% nitrogen so you’re only varying the remainder which is 21% oxygen and then some argon and such.
Unless you're filling with a York, then some nonzero quantity is oil.

At the heart of it, we already run 78% nitrogen if we use compressed air. It is virtually impossible to get pure nitrogen in a tire anyway since you would have to seal the beads and pull a vacuum or run two valve stems opposite and fill one while purging the other. At best, we are going to be running some amount slightly less than they want you to believe and slightly more than you have now.ok.........i thought i read the molecules are bigger and therefore don't permeate materials at the rate air does. or pump in moisture if you don't run an FR.
I once won a 50 dollar bet from a guy who built KOH type race cars for the desert. He said the reason they run nitrogen in shocks was to prevent pressure changes under temperature changes. I told him that science said he was mistaken. He said to hold up a minute, he was going to call Lance and get the answer straight from the horse's mouth. He made the call, chatted a bit, came back and handed me my 50. Ok thanks, so, who is Lance? Oh, that's Lance King from King Shocks, he says we run nitrogen because it is cheap and convenient and isn't compressed air which most don't have a good enough dryer for to get rid of moisture which is bad. We can run air if it is dry.so all these nitro filled shocks are just a purity thing for the internal sys then basically?

got it.....thanks for the clarification...........so the only benefit is it's contaminant free? moisture being the main culprit.
edited............been reading .......does not support moisture or combustibility, most say, it will keep a wheel at pressure up to 30% longer (based on permeation) and for our application, temp swings effect both air and pure gas equally..
i cannot find info on humidity levels of pumped air and effects to anything pressure related. most state it's just not good for the inner rim surfaces and can degrade it.
is this accurate to most? sorry toximus , keep the gas for the shocks.
We all learned something! I previously thought permeation would be less with nitrogen. Turns out that either of the molecules are larger than the liner used in tires.

Think about it. If the permeation thing were actually true, the 22% of O2 would leak out of the tire - and you would be left with close to pure N after a few fill ups...
The -8 45 goes onto the adapter for the return side. It has to be clocked to route the hose into the gap between the condenser and lower part of the grill. Once it is clocked, then it has to be tightened down onto the male portion using two wrenches to prevent damage to the hardline. Generally depending on the rig, we have to remove it from the return port, tighten it and then put it back in. Not having one line cross over the other one makes that far easier.

to be clear the permeation i read about was over time and not a wkly event, it was stated at a month or more.. 30% is a meager improvement in this case. assuming every seal on each wheel is equal.
i'm now more focused on why the don't use it because of water vapor contamination issues in equipment like shocks and struts and now wanna ensure i keep my locker air sys free of vapor post compressor. it's been on my punch list. but now it's importance is clearer to me.
That is a perfect example of the exact opposite I explained to you.
