something just occurred to me,
the regulator,
it's made of a "white metal" like aluminum,
i know i haven't seen every make and model of High Pressure Regulator on the market,
but shouldn't they be made of Steel or Stainless Steel?
if that reg is made of aluminum i would suspect a knock off of the real deal
and this could be a very dangerous thing.

If there were threads and the reg half were to "explode" off the top portion, it would be evident on the reg top threads, and they appear to be fine. I'm not buying this, seems awful suspect, at least according to the account?

If the crack developed fist, as it likely did, then the threads of the stronger material would stay intact. So when the crack went across, and the lower threads all of a sudden weren't helping to hold the reg on anymore, the increased force on the top part of the threads increased, thus ripping the threads out. In this case, the threads on the tank, being the lesser material. I don't think the real problem here lies with the threads.

regs have been made of aluminum for a long time now. I know even my air america armageddon is made of aluminum. The crossfire regs, myths, nitro duck ireg, cp's, all aluminum regs.

all I can say is I'm glad my regs are all stainless steel, maybe heavier but less likely to fail at the threads.

Have you heard the saying "only as strong as the weakest link" or something of the like? All inserts for fibre wrapped tanks I have seen are aluminum. By insert, I mean the bit that you thread into. All the aluminum tanks are, you guessed it, aluminum threads. Granted, the aluminum tanks aren't rated for 4500 psi, only 3000.

be that as it may, i personally would never use a high pressure reg made of a meterial that is as easy to crack/break/fail as Aluminum. just not a good idea.

that being said here are 2 of the pics i tried to adjust the light levels to get a better look at the actuall break, but the flash really did burn the pics:

People fly in planes made of aluminum every day. Steel is very rarely used for structural components on planes. It is an incredible material. I sense that there's a story behind this

Do tell

all fibre wrapped tanks have a drawn alluminum liner, they are rated for higher presures because of the fibre wrap. the part that the reg screws into is part of that liner.

Luxfer: Paintball Cylinders

luxfer cylinder info

the reg probilly broke because of human error, not any of the manufacturing processes, If alluminum is so weak why do all the major automotive manufactures make engine parts out of it, ie, pistons, heads, 2 of the most stressed componits of the engines running in todays cars.

are these planes pressureized to 4500PSI ?

no.

you tap the fill nipple. liek u screw the tank on by hand and then just tap on it a lottle tighter for extra pressure (cause god knows I can't tighten anything with my girl hands.) It's what the manifacters do. It works just fine. I wouldnt suggest beating on your reg with a hammer but a few light taps with a rubber mallet to the fill nipple in the counter clockwise direction tightens that baby up

You sure it's counter-clockwise?
