2 cylinder tuxing 4500 psi compressor PRV

[ssgmac]

The scariest but safest failure I've had was a Chinese brass foster clone letting loose under pressure. One cc of 250 bar air was equivalent to a 22 pistol with no ears

The bov letting pressure out isn't a big deal, rapid failures get sketchy. Burst discs are a little sketchy. Pipe threads and hoses letting loose get

This app is killing me with its interface.. anyway, I've always wondered about those brass high pressure fittings. They don't look any different from regular fittings that are rated for much less pressure. And they're brass. WTF. But if that's all I have left to work with, I'll throw caution to the wind in a heartbeat LOL

The prv is the weak link when it's not a follow hose or piston ring or stripped out fitting or whatever part of the system might wear out one day. The PRV is more of a high limit switch that won't let us go any higher.

Any bottle that could explode isn't part of the compressor. If someone wants to make bottles explode with their compressor, it doesn't have to be a SCBA tank, and it doesn't have to be 5000 PSI. You can get an impressive explosion of a 100 psi compressor and a water bottle or Gatorade bottle and Schrader valve and some rocks. Or just a gatorade bottle, some water and some dry ice.

I posted this hack for those who got a 350 bar airgun but can't find an affordable compressor or doesn't want to buy a new one because the 4500 psi one is still working strong. If anyone reads this and decides they want to over fill an expired SCBA tank past 4500 psi. I say, go for it. And I hope their next of kin post the video on YouTube so I can get that little bit of satisfaction as I watch them leave the gene pool, knowing I did my part to help eradicate stupidity from future Generations.

But seriously, if the tank is going to blow before the burst disc, it's going to happen before 5,000 PSI

You are also missing that the various parts of the compressor may not handle the added pressure. Piston rings and various joints in the high pressure side. Highly unlikely with an 11% increase in pressure on a new compressor. On a compressor with some age to it, that could get interesting. With the amount of vibration fatigue in the parts is possible, but an 11% increase would only accelerate a failure.

As for those other explosive releases, materials is everything. Elasticity of plastic, rapid expansion causes whole body failure.

Nope, I covered the extra wear and tear on the internal parts, a few times. ..I think I even mentioned the rings in the comment you're replying to.. I'm well aware of how dangerous rapidly expanding Plastics are. Some Plastics, like pvc, shatter like glass when they explode. That's why you should never Pump a PVC system up with air higher than 5 PSI. Anything higher has to be a hydrostatic test

The bottom line is you go to war with the Army you got. Nothing lasts forever. And I can pick up just the compressor without any filtration or anything like that for just a couple hundred bucks.
