on off for my geddon???

[dynorock1]

im shootin an ir3 with a geddon setup. I would really like some type of on/off on it, so that i do not have to take the tank off. Is there something i can put between my geddon reg and mini reg that is an on/off or something like that???? If you know of anything please tell me. Thanks

Warped Sportz makes on/off elbows. They're like regular 90 degree macroline elbows, but they have a little on/off valve. They work great, I have one on my geddon.
