Exclamation NEED HELP (co2)

I have a fluval 88g co2 kit.
The kit hasn't been used in quite a while and I recently got new co2 cartridges for it, they are the correct size, thread, and brand. I can not get the co2 to work. I now have everything detached except for the co2 cartridge and the valve system, it looks like the hole where the c02 leaves and comes into the air tube might have rusted over, is this even possible? I literally can't get any co2 out but the valve does give me a psi reading of about 1,250.

I would not expect those parts to be steel and rust. But is it possible that is has some other item mashed into the fitting? Have you tried plucking it out with a pin, needle, etc. ? If I understand it right you have a valve on a full canister but the opening is plugged. How about holding it facing away from you and opening the valve for a short burst to try to force something out? The CO2 is not dangerous in any way other than if you fill the room or get the super cold gas on skin long enough to freeze.

That's plenty. Make sure your threads are lined up and the cartridge is 100% punctured.

The fastest way to success is patience.

1250 psi is high for CO2, its normally around 800psi unless the bottle is hot or been out in the sun.

It sounds like something is wrong with the kit, be careful.

Thanks for the replies! I figured it out, the part of the valve where the co2 leaves the regulator and goes into the air line tubing did in fact rust, I used a very tiny nail and hammered it in to the whole which got it to open up, the psi dropped to around 900 as well.
