Source for oxygen fill valve

[[email protected]]

Okay, I'm just being my normal cheap-ass self here. Wings and Wheels has the fill valve I want on page 36 (Aerox PB (Schreder) In-line Fill Valve - for 34 bucks. That seems... um, a bit high. Is it that special?
Thanks

Nothing wrong with shopping around. Suggest try Aerox direct, as they
have great customer service, or perhaps Spruce, Skygeek, Chief,
Wickes, etc.

Knock yourself out, and save a few tens of dollars. You could go to the junk yard and cut a Schreader valve off an air conditioning unit and build your own... but oops that may not handle anything like 2,200 psi or more of highly reactive oxygen. And nah don't worry about the possibility of an oxygen explosion with improper seal material or lubricants used in the fitting.

These are life support systems and involve handling a fairly dangerous compressed oxidizer. Seriously buy the part from Tim and stop asking for dumb advice here.

And even with the right part be careful assembling this make sure it threads in all the way (its got to handle 2,200 psi or so pressure), no lubricants, don't get it accidentally oily by handling or leaving on a workbench, use Oxygen safe PTFE tape (which may be overkill but mostly just says the PTFE is not contaminated with solvents/lubricants and is less likely to cause an oxygen explosion and kill you). And be prepared, that tape will costs you more than the crap PTFE tape you buy at Home Depot.

Hello, if it makes the cost from Tim easier to accept, M&H wants
$50.00, also as trivia, while the fill valve would see 2200psi on a
full fill, the typical "jumbo D" 5.25X19 inch bottle at that pressure
is containing 640,000 lbs of force, not subtracting the ambient 1
atmosphere. WOW,


Good Lift,

Think psi, not total. What's the pressure on that ~1/4 inch diameter valve
at 2,200 psi? About 107 lb.

I checked that out early on. I was really looking for a source of an
'industrial' nature. Often we pay a premium for identical parts/
assemblies that are commonly used in industry, just because we're
buying them from 'aviation' retail sources. This may or not be the
case with the 'MS' fill valve, but I certainly wasn't able to find
one. I just ordered the filling block from Aerox. No, it wasn't
cheap.
