Daystate Brand new to airguns.

Hello all,

Brand new to this sport, just bought my first FAC air gun and I have a few questions for you guys.

From what I've been told, in almost every country high pressure air vessels have to be Hydrostatic tested very 5 years (or so) with a "total lifetime" use of somewhere around 15 years (or so) which I'm good with for safety, but what about airguns like say an AirArms S510 or any other air guns that dosen't have a removable high pressure air tank.

Or say something like a water removable device like a "Tuxing water seperator" that are also charged to 250+ bars, or even the air whips we use to fill the guns/tanks?...

You’re going to get a wild variety of inputs but few will be based on the manufacturer recommendations or local / federal / international regulations.
I personally follow the rules but I also completely service my PCP’s every 3 years - period! I enjoy them so much that I consider it a cost of my hobby.

I've oft times wondered about that. Our tanks require inspection but none of the supporting hardware does.

The tanks because they store significantly more energy than the supporting hardware. But if you ever have a hose let loose you would know just how much damage it could do.

But big filters like the Tuxing dual could store some high energy.

How you could test them without damaging them? Take them above their working pressure but below their original test pressure? Where would you get that done?

Then there are more than a few people that use aged out SCBA tanks. Haven't heard of any of them bursting.

So the inspection standards are probably excessive but not unreasonable.

I may be wrong but i have not heard of hydrostatic testing for the bottles or tubes that go on an air rifle. I have had hydrostatic testing done on my big SCBA tank. If you are taking your tank to be filled by a scuba shop or a paintball store that can fill to 4500 psi, then they require that your tank is certified.
The water filter you speak of is an attachment for when you run a compressor to remove moisture from your fill. There are many compressors on the market. Best to do your homework before buying.
Air whips i have seen in 2 types .. a slow fill micro bore and normal whips. Micro bores leave less air in the hose, but is slower to fill a rifle. Conserves air.

I have never heard of a PCP bottle need of help.

What eventually happen is am leak because material devasting....

I that would ever happen, just buy another bottle (as big as possible).

If you dig Into the details of it in the states it's dot rules for transportation on public roads and they've made fill points adhere to enforcing this, because you have to travel with it. I have old tube guns, and even older paintball cylinders I still use (personal risk choice). You can always inspect them yourself or, there's some other fun things if you really care to get scientific.


You can make your own hydro test vessel and look up the test pressure and expansion allowance for water displacement. Usually 5/3 pressure rating.... But you don't fill with air for energetics reasons, you use water. (beware hydraulic injection injuries too). When they burst it's a split and pour usually and not a 10k psi oil jet like heavy equipment.

Iirc the youtube channel AVE did some pressure testing like this with vessels filled with water, an appropriately rated line filled with water, hooked up to a milwaukee m18 cordless grease gun to achieve the insanely high pressures needed to test. My gen1 mrod tube is probably the riskiest vessel I use but there's cylinder brands I trust like luxfer and sci(now owned by luxfer).

I've been around hpa since it came into paintball when co2 was the standard and haven't seen an incident in person and every video instance I've seen is the fault of users doing things you aren't supposed to do(heli coils, oil, oxygen fills) . This cylinder is in immaculate condition but is an example of a risky one... I keep it for a future project in the 250 psi range for a windshield washer fluid air source for a vintage truck. It's glass fiber only.

Most European mfgr state to replace certain items like air tubes after a specific time limit - again, I would specifically ask a the manufacturer about any specific items you have in question. Go to the source.
as I first mentioned, your going to get a wide variety of different information and in this case most will be people shooting from the hip.
