This is kind of a ignorant post, of course 4k psi is dangerous. Quality parts are engineered to be safe way beyond that but if parts are fatigued, broken or malfunctioning, caution should be used as hpa is dangerous.

ignorant huh, spot on I say.
Jay put your compressor out in the shed, hook it up securely, turn it on and RUN !
If you are scared of something you feel you can’t control don’t use it .
It is not dangerous to me anymore than what I did for a living. Knowledge conquers fear

Seems like I saw a video of a fella who had a large tank burst at high pressure. Almost killed him and he lost a leg. Reckon he'd say HPA can be dangerous ?

I'd like to see that video. You would think it would be shared more within the airgun world. I would also like to see the full true story of what caused it. Until then I'm going with the theory that they split and leak off as opposed to exploding.

I think he is referring to an incident from about a year ago where an airgun store employee in Idaho was filling a small tank that exploded and resulted in his leg being amputated. Lots of conjecture but I never saw anything definitive on the cause. https://www.airgunnation.com/threads/joe-shneehagen-accident.1311820/

When pressed for details that would have clarified the whole mess, the topic went dead silent. Hmmmm?

From what I remember seeing, it looked to be a paint ball tank, thin aluminum - CO2 pressure I presume (~1800 psi max)

When I used an aluminum dive bottle for my PCP, the bottle was heavy as heck and only rated to 3000 psi. My modern SCBA tanks are much different construction than those sc-U-ba tanks.

Watch that video this morning.. I think they alluded to the issue being valve and thread related and not an exploding tank.
I could be wrong.

your right I thought I addressed that but I reviewed this subject and not there.
Commercial and homeowner compressors for lets say auto mechanics are large steel tanks subject to dreaded rust.
The water collects at the low point and over time weakens the tank. This is only at a pressure of around 150 psi.
My 30 gallon is probably going on 30 years old I drain and leave open but how long do you trust it. We are talking
about comparatively small aluminum or aluminum wraped in carbon fiber tanks.
Vacationing in the Keys once went on a dive ( tourist type ) was amazed at the handling of the air tanks. Seems these
professional dive instructors didn’t give a second thought to non gentle moving the tanks.

Ya know... this would also solve the problem with some guns not wanting to start filling unless they get a blast of air to seal them.

I figured out the u2 without the blast resealing. Manually Set valve against seat (muzzle up orientation) Re assemble holding vertical. put back-pressure cap on muzzle. Seals immediately. Other Balanced Valve guns, Not so sure.

Today I went to fill an airgun and while the pressure was building according to the gauge on the compressor, the gauge on the gun was not moving at all! At 100BAR, I stopped the compressor and released pressure using the bottom bleed valve on the compressor.

I thin removed the GX Filter and just used a regular in-line filter and it filled the gun just fine., so it's not the gun, it's the filter!

I took the filter apart and everything looked fine, I tore down the top end, and it has a stack of belleville washers in the top of it that looks as if it must somehow regulate the output, but why would it be preventing air from exiting the filter?

Anyone else have this issue? Is this normal, and I just need to let it keep building pressure, or is something wrong?

Thanks...

It's DESIGNED to work this way. Heck, that's why I bought it when I didn't need it! :love:

Wow, I never said anything about being scared, are you having a mental break down? I guess the Darwin award goes to you, congrats you won😂
