HPA tank RSS

The field filled you to 3,000, and twenty minutes later the gauge reads a few hundred less. An r/paintball player asked why their 48/3000 tank "loses pressure right after airing up." Short answer: an HPA tank hot fill heats the air, and the reading drops as it cools. Usually nothing is broken. Why does an HPA tank hot fill read low later? Fast fills heat the air and the bottle. Hot air pushes harder, so the gauge reads high at the station, then settles as the tank cools. The New Jersey Scuba air fills page says the proper way to...

You sold your old bottle online and now you have to get it to the buyer. An r/paintball player asked how to pack and ship it after doing the same. Short answer: you can't just drop a charged bottle in a box, and before you ship an HPA tank you need to empty it and check the carrier's rules first. Can you ship an HPA tank by mail? Not charged, and the empty case is murky. Compressed air fits USPS Publication 52's Division 2.2 definition for nonflammable gases. It bars any container whose internal pressure tops 180 psig at 130°F,...

The tank holds air fine until you fill it, or it hisses from the fill port while you're gearing up. An r/airsoft player posted "HK Tank Fill Nipple Leaking?" with that problem. Short answer: an HPA fill nipple leak is usually a worn poppet o-ring or a thread seal, and both are cheap fixes. Why is my HPA fill nipple leaking? The fill nipple is a quick-disconnect male fitting with a small poppet inside that lets air in and keeps it there. ZDSPB's tank tech page calls these low maintenance parts that may need an occasional o-ring swap when they...

Your pistol still cycles, but the needle is hugging the bottom of the dial. An r/airsoft player asked "When HPA tank is completely empty?" and the honest answer is that your HPA tank gauge and your gun will tell you different things. The gun usually quits being useful well before the needle hits zero. How do you read an HPA tank gauge near empty? The tank gauge shows bottle pressure, not what reaches the gun. Player report: replies in that thread said the tank is empty when the gauge sits at zero and no air comes out when you connect...

You threaded the regulator onto the bottle, it hissed for a second, and now you're wondering if you skipped a part. An r/airsoft player asked the same thing about an on-tank Wolverine regulator. Short answer: no. An on/off ASA is a convenience part. Your rig shoots the same without one. Do you need an on/off ASA? No. It makes tank swaps easier and kinder to the seals, but it doesn't change velocity or consistency. Player report: replies in that thread said you don't need one, though it's nice to have because it saves wear on the threads. Without one, players...
