Umarex CO2 P99 Leaking

Post by 99999Dragons » Thu Mar 06, 2014 8:42 pm

I'm not sure why, but recently and all of the sudden my P99 leaks CO2 for a good 10 minutes after inserting a new cartridge. As I said, I don't have any idea why, but maybe someone else does. Also, just before I noticed this happening, I realized that it would occasionally shoot 2 or even 3 bb's at a time - are these issues related, and does anyone know what could cause them and how to fix it?

The leaks are probably due to the seals in the gun being cracked. C02 is a dry gas and will not lubricate the seals so after time they will dry up and crack without proper lubrication.

ummmm...all "gas" is "dry".

More likely is that your P99 is just failing.

Airsoft pistols were never designed to "handle" CO2. CO2 is a 350-900psi gas versus 3 Chain Organic Carbon Gasses that run between 90-150psi.

And all that is holding back that pressure is a cheap restrictor disk...as that disc deforms...more pressure gets out and that will ruin your pistol...which looks sounds like the case with your P99.

Well green gas is just propane with silicone right? I was just saying c02 is a "dry" gas because it doesnt have any added lubricants. But please do correct me if im wrong (no sarcasm intended).

Bottom line, and I believe most people would agree with me, C02 pistols are a waste of money, they generally are of poor quality, minimal upgradeability, and are very hard to fix once broken.

"Real" Green Gas is a Refrigerent - ET1000

Perverted American Mutt Gas that is being sold a "Green" is a propane mix of unknown proportions.

Alright thanks guys. I do intend to get a gas pistol eventually, but was just wondering if there was maybe a hotfix for now. :D

Buy a GG mag for the P99 and stop using CO2.

The drawbacks of CO2 far outweigh its advantages.

Still new to airsoft, what's the drawback? The only drawback I'm aware of is co2 does not lubricate. Better for cooler weather.

If you look at the Elite Force 1911 thread in the general section, guges did a good job explaining to me why green gas is preferred.

It is a FALSE myth that proper lubrication of a GBB is via the gas.

That is like lubricating a car motor by dumping motor oil in the fuel tank.

You do not lube a gbb this way. And sadly "professed" airsoft techs continue to propagate this falsity.

Thanks for pointing that out. I just bought the KWA HK45 and thought for the most part it would be good to go, but my eyes have been opened lol.
