Anyone know the highest ever used, or tested? While shopping for a booster pump I discovered some that go up to 32,000psi! And it got me wondering...
N/A The most PSI ever in an airgun?

My buddy john bowman that builds the scandlous big bores was running 5300 psi in a 58 cal he built for his grandson...

The AEA sonic (temporary name supposedly) which isn't yet on the market has a tank that can take 7000 psi, however it regulates down to 4,500 or so peak shooting pressure.

O-rings will likely fail due to extrusion beyond 10,000 psi in most applications unless they're custom and greater than 90 duro, or have tolerance so tight NASA would do a double take.

No gun valve will open at 32k psi. Wtf. Most would be 4500-5000 psi regulated. Any higher and valve lock

Well aea is apperntly doing it with 7000 psi if there junk can do it... the custom usa big bore builders can defintly do it... but better

Challenge accepted, my pilot valve has 349 lbs of holding force at 32000 psi...
Akin to a conventional .30 or .357 at 3000 psi...

Aea guns that fill to 7000 are regulated to like 4500 or 5000 psi. Also 7000 psi vs 32,000 psi is like comparing a 120 psi compressor to a 4500 psi compressor. They aren't even in the same league.

Gotta be built to handle it... and its gotta be able to seal up too.But... but... MO POWA! How about 10kpsi of helium? Can you imagine the powa!

7000 vs 32000 is 4.5x difference, where 120 to 4500 is 37.5x....lol. Better to compare 1,000 psi to 4,500 psi.

The hammer would be propelled by a .50 BMG blank cartridge and would be constructed of a depleted uranium core

Conventionally valved, yes (4000+ lbs of holding force), balanced valved, yes (2000+ lbs of holding force), pilot valved, nah (400-500 lbs of holding force)
With a pilot valve you could probably actuate a valve at near 32,000 psi with a standard mechanically driven hammer with modest weight, 150~ grams and around 18 lbs of spring, given a side lever of 3:1 that would be 6 lbs of cocking force.
One issue would be more material strengths, but, with titanium and carbon fiber combined, not impossible.
The biggest issue more so would be the closing force on such a valve...even with a .061" stem, you'd have 100 lbs sledge hammering that valve shut, with a.125" stem, you would have 392 lbs sledge hammering the valve shut, both very destructive and hard to believe the valve seat would last long, and a .061" stem would probably snap trying to open 500 lbs of holding force, so that would be the biggest practical caveat. .125" stems have proven to withstand opening 400-500 lbs of holding force, but man, having 400 lbs slam the poppet to the valve seat, over, and over every shot cycle...good luck.

You may be right, and other pneumatic seals may be best, however I doubt the AEA compressor that pushes 9000 psi and is software limited to 7500 is not using any o-rings

Not exactly an airgun, but what pressures are obtained in light gas guns?
I'm sure they exceed 32,000 psi.
