The pin valve on my 20 oz c02 tank is leaking, can these valves be replaced or do I have to replace the whole bottle

press down on it with a wrench or something and let go, it lets the valve reseat.

You can replace the pins. Just make sure you know how.

No I think my pin valve is actually bent. It will fill, but them it all leaks out. I think I'm just gonna have to buy a new tank because I filled it today and my black tank was white with frost. Not a tiny bit of frost we are talking about a layer of frost/ice all over the tank.

they are replaceable but it's better to have a shop change it cause if it's not
tightened properly then it can unscrew when removing the tank from your
marker and away goes a small cruise missile, and if you have a shop change
it it would probably be close to buying a new tank, then you have to take
into consideration how old the tank is and if it needs to get hydro tested
soon if that's the case save the money and replace it, and invest in a thread
saver cap in case it was a drop that damaged it

Heh actually it had a thread saver cap already. And then one day I noticed that it was broken so I dont know what exactly hapened, but I thik it got dropped and that broke the thread saver cap and did some damage to the pin as well.

Its pretty much REQUIRED to have a shop change out the tank valve. DO NOT mess with it yourself, if you screw it up it can and will kill you or someone else later on.

I have a similar problem, on two tanks that i just bought, they both, as soon as i screwed them into a gun (they were fine from their first fill) and took it off, there was a sliver something sticking out beside the pin, and the tan was not sealed...my temporary solution was to plug it back on a gun.

A friend of mind told me that its some o-ring inside that they said was easy to replace, once tank is empty.

One of the tanks is from Dick's, so i'm thinking about taking it back and trying to get a refund/replacement.  The other was on a clearance rack b/c it was 2 years old on the self.

if the silver piece was hard it could have been a metal shaving from when
they tapped the threads into the tank that finally worked it's way out

That was a mistyping, my grammer was horrid in that post, later in the post i talk of that being an o-ring, its definately a soft rubber like substance that has worked its way into the middle of that valve.  Now that the tanks are both empty, i might take the cheaper/older one apart to see what it is.

Go for it, as a learning experience. But I would condemn the tank after that and never fill it again. Tank valves require a certain thread sealant, a certain torque onto the tank, otherwise its extremely dangerous.

Its sortof like taking the brakes off your car. Sure, its straightforward to do, but its also likely to get you killed if you mess it up.
