Co2 cartridge leaks when inserted,

Hello K Brink,

Kind of like deja vous (all over again )...
Pretty sure: This is the same Question I answered
yesterday (no / yes? ).

There is no going back... Once the CO2 cartridge is
pierced... there is no way to salvage the cylinder
until it is FULLY expended...

If you unscrew the chamber the CO2 will ALL be released.

Just ONE word... If your cylinders are depleted... ALWAYS
check that the SEALING O-ring stays with the hand-gun.

Just make sure yur SEALING RING is still in the "gun"
and NOT STUCK to the ... co2 CARTRIDGE.

I am just saying...

((been there... Done that))...

Yes there is an "O" ring seal that is supposed to be there.

The crosman 1008 does indeed fire pellets! NOT BBs. ONLY pellets.

Your seal is probably out...

Take a short strip of teflon tape and put it over the end of the co2 cartridge, make sure its in straight and tighten, works good.....:)

The Phantom Break-Barrel does not use CO2. It is a spring-loaded break-barrel weapon. If you really do have a CO2 gun, check the rubber seal around the outside of the cartridge puncture needle.

Well that takes me back! I have an old Daisy 1200 -- essentially the same pistol in a different brand.

My Daisy has a hand-turn screw to hold the CO2 cartridge in place, and you have to tighten it quickly until the leaking stops. It does this by pressing the cartridge up against a nylon washer to form a seal (and of course pushing it into the piercing pin to get the CO2 out!)

With age, I'd expect that nylon washer to get stiff or crack, making it harder to form a good seal. You don't need an exact replacement part, but if that's happened to yours then you will need to replace it with something more-or-less the same size as the original.

Replace the seals.

You need to check the rubber o-ring seals both in the plug and there could be another up in the gun where the cartridge end meets the inside. If you have a broken o-ring you should be able to find one that fits at your local hardware store or store that sells air rifles. Hope this helps.
