    Quick disconnect on gas regulator?

    Anybody do this? I'm often switching between different cylinders and machines. It seems like if you used high quality connectors you would be good to go. Is this practical, or just an efficient way to waste gas?

    I have Koike quick disconnects on my portable machines but they are to for the cutting torch, and shielding gas setup. I remove the hoses with the quick disconnects, remove the regulators and store, then install transport caps. Welders are chassis mounted on running gear.

    I use them on my Passport since I was switching between CO2 and Argon when I use the Spool gun and on the Tig machine I had at one time.

    I use Western they can come disconnected when dragging then. I looked up Koike and they look a much better design what do you think.

    I have the Koike brand on the torch ends of hoses also as my hoses are on reels. One needs to ensure they are coupled securely as I've had them pop loose twice on me. Hoses are 100' length so no splices susceptible to dragging. They do look a better design but I need to be bare handed to work with them due to physically small size.

    I have them on the torch end of my hoses for switching between cutting and heating handles. I love em... if the O-rings wear you can get leakage, but as long as you keep them in good shape you should be good. I've never had a problem with them. If you peruse the oxy acetylene threads, it seems to me O2 Dr. had a brand he recommended but I forget what the name was offhand.

    I just finished gathering all of the parts to this very thing exactly the way I want. They are all rectus 20 series connectors. I've tested two of them with soap after a bit of use and found no problems yet. Time will tell how well they hold up in my shop.
    The final configuration will have the male nipple on the equipment vs. hose to prevent sealing problems from getting dragged around.

    Re: Quick disconnect on gas regulator?

    I have these high quality Aero QDs on all my MIG machines. I just removed the restrictor from the outlet side of the flow meters, installed the QD, then installed the restrictor on the outlet side of the QD, right before the hose. That way you have the higher pressure going through the restriction of the QD. I have checked it with the float ball tool and it is as accurate as it was before.

    I do it for C25. I have a big cylinder with a Y splitter and two hoses on a separate dolly and no bottles on my machines.

    I use Western stuff on all my Q/C's with no issues.

    Duh, no! You have to defeat the built in safety in the valve first. After that just duct tape on any piece of hose. It don't get much quicker disconnecting than duct tape on a 200psi fuel gas line when you light it off!

    These are the best I have found.
    http://oxyfuelsafety.com/quick-connectors
    I have them on both of my oxyfuel rigs. They are not cheap. They are machined out of solid brass and stainless steel.
    Here is there catalog
    http://oxyfuelsafety.com/quick-connectors
    look at pg 6,7 and 8
    I purchased mine through airgas.
    You can purchase individual pieces instead of the packaged pairs. So if you had 3 tanks and one welder you can buy just what you need.
    Beware, soon you will want everything running quick connects
    Here is my obsession....uhh....collection

    They also make flash suppressor / quick connect combinations which I run on my regulators.
