Storage

[Gunny]

Hoping to get a solid answer. If it is some where in previous post I apologize. How long cAn you store your pcp with air? I’m guessing it’s ok for a while but not a long time. If I deploy for 6 months what’s the best way to store my impact?

thanks for the help and all the good gouge.

thanks Guns.

Length of storage is important, you CAN store for years if you want, at high psi.

But, mostly this has to do with seals. Soft seal material can become deformed with high pressure, so best not to leave under hi pressure over time. Our modern harder seal materials are less affected. BUT, still a good idea if storing to reduce pressure to some nominal level; enough to keep the valve closed and keep debris and dirt from entering the system, but not enough psi to deform the seals. I’d suggest storing it with 1000 psi or even less for long term storage.

Good luck with your deployment.

1. Indefinitely. You should alway keep air in the gun. Not doing so can cause the seals to start to fail. How much? I keep mine fully charged.

2. Store like you would any other any other high quality expensive piece of equipment.

I store mine at the psi I normally fill to, a example would be my 3000 psi airguns, I store them at 2800-2900 psi.

The worst whing you can do is storing it empty. It can deform and damage the seals, never leave your PCP without some air inside.

I do not know why would leaving it empty cause any damage to the o ring really. I am sure very few actually know how a basic component as an o ring functions/seals, it works differently to what you have thought really.

I work in the service industry with systems under vacuum daily. Deformation is the life and function of the o rings, they deform in the groove that is actually how they seal!

over time they all fail sooner or later, no matter if you leave it empty or full. Maybe you have some poorly designed gun on your mind when they got the material, groove size and seal size wrong...



I think it is more critical not to mechanically damage them by turning while under pressure, for example if you mess with the bottle. Or mess with the regulator adjuster. You should fully depressurize a gun before you start turning any components what have contact with seals.

replacing an o ring should be trivial as it is like a consumable, when you think about it: i would consider ease of access and serviceability more important than the looks!

for those who want to learn how o rings work just take a picture on this site

P.S thanks for the - es, i just cant stand when people post BS

Guns,

Semper Fi, 7234 from 76-82. I have an Impact and wouldn't worry about storing for 6 months. The manual says not to go below 1000 psi so I would store it at that level. Although I have an extreme big bore and store it year round at 4500psi. As stated by milacik, all o-rings will eventually fail but they are cheap and most are easy to get to and replace. Just make sure you come home, the Impact will be fine when you do. Happy birthday, (5 days late) Azycray

If you used the gun every day for 10 years it would've been stored at that pressure for 10 years. Put a little silicone grease on the the breach o-ring and that's all I would do. Thank you for your service.

For regulated airguns, store them UNDER or ABOVE the regulator pressure????

Gunny,



Semper Fi (6821 '81 - '86) To reduce your worry, send it to me for safe keeping. I'll make sure it gets cycled a few thousand times in your absence. 

My Red Wolf and Bantam don't mention a PSI for storage so I can't get excited about it.

Gents, thanks for all the good advice. I really appreciate it.

Smitty 6821? Isn’t that a weather man? Also you joined the year I was born. Lol all you old timers are the reason I joined.



Azycray, Smitty, and any I missed Semper Fi brothers and thank you for your service!

Gunny,

Yup, I was a weather observer, your the first Marine thats ever known that.

I had one in Afghanistan. He was basically a guy that got paid to guess about the weather. Hahaha he had some high speed gear and we depended on him to play trips out. Birds don’t fly in red air and he was the one to make the calls.
