It's called metal fatigue. It happens.

[Doc Nickel]

A pressure tank is intentionally overfilled in the course of hydrotesting. Point in fact, a 3K psi tank is filled to 4500 when tested.

However...

There's a reason that fiber-wrap tanks have a finite lifespan, which includes either three or four hydrotests, and only three or four hydrotests. The testing itself fatigues the tank, and after just a handful of tests, the tank is known to be damaged to the point it needs to be decertified. (Meaning after the 15-year lifespan, the tank can no longer be legally tested or used, regardless of condition.)

So one overfill won't kill or blow up a tank. But more than one will damage the tank, and risk having it not pass it's next hydro. Keep overfilling on a regular basis, and you risk having the tank actually burst.

Hopefully the majority of buyers will be reasonably competent and will properly adjust the output if necessary. On the other hand, the typical buyer of something like this already has a 4500 psi tank anyway- I can't see somebody blowing $400 to keep the steel 53 on his Tippmann topped up. (Though stranger things have happened. )

Bottom line? If you buy one, and only have a 3K psi tank (or have both kinds of tank) pay very close attention to the fill pressures of the lower rated one.

Which I find quite a racket if you ask me.. that really the part that determines the lifespan of the CF tanks is the hydrotesting and that is what kills it. Seems like there should be a better way to test them... like xray technology that will allow the bottle to be scanned to check for any tears/fractures and then put back into service. Seems a much more logical avenue. One thing that's always irritated me about the CF bottles.

Hose fill kits

I am assembling the proper rated fill hose kits complete with gauge. I will have pics up shortly. Safe...cheap...done...

[Beemer]

it will. i've had 5k disks blow at a 3k hot fill.

Whats a HOT fill. Is that like what we [I] call a SLAM or flash fill? Thats one nice thing about the Shoebox, you get a nice FULL fill. No loss of pressure from cool down after a fill.

An old burst disk can go at anytime not just from an over fill. Like Ando said fatigue.

Its funny how this brings up SAFETY questions NOW, when for years LOTS of folks have been using plastic line downstream from a 4500psi pressure vessal and dont THINK twice about it.

Send your gun out to a third party,NASA or UL and the first thing they will do is make the upstream part fail and see what happens downstream.

Who has the only valve [gun] still on the market that actually SAYS rated to 3000psi? And thats underrated when in fact it was tested at over 5000psi.

The shoebox has a burst disk built in. It will blow. It has been tested.

Nice................Did you blow up or break your Shoebox yet? Could you send us one of those hose kits?

I was just talking about that with another AO'er... We both use WDP Angel AIR tank regulators on some of our markers, and while they're awesomely adjustable, they tend to blow seals if you "flash" or "slam" fill them.... They prefer a slow fill, and neither of us will bring our AIR-equipped markers to fields that won't let us do our own fills.

The Shoebox will become a must-have for AIR reg users.

My Angel Air is the same. The first fill needs to be gentle. After that, the top off isn't as critical.

[PB_RoB]

I so want to be in the first 100 to be able to buy one.

Is there an official waiting list for this? If so - where do I sign up?

This is a Gotta HAVE IT for me!

[BenoitOWN]

How come hes da man when I was getting Ninja to make a proper stainless hose kit? Tuna tell me it not a cheap paintball gauge ... ive seen them fail hehe.

[Tunaman]

Because you got it right...I am da Man! I dont want to see my friends hurt so I wont use any cheap crap. No mini gauges either as they are not reliable enough. 3000wp stainless line is not good enough. If it isnt Mil Spec I am not using it. So price out the Mil spec stuff and see if you still want to do it. My parts should be here tuesday so hurry.

We use this at work for hydraulics.

Only thing about that hose is the ends aren't removable. It looks like a test set we have in our tool room. Exact same connectors. Someone messed one of the connectors up and we wound up replacing the whole line.

[Tunaman]

That wont work...metric.
