    I finally got around to pulling out two SCBA sets today in prep for a fun filled 4th. One tank had a CGA347 fitting but didn’t have a cut in thread so my fill station wouldn’t work. 

    The other was a different setup. It only had the on/off knob and another valve. I have a Joe Brancato Guppy and checked to see if the micro bore hose would fit and it did. 

    Here’s where I f’d up:  I got all excited and hooked that cylinder up to my PCP and although it wasn’t full, it topped out my rifle around 200 bar. It was then I noticed there was no bleed valve. 

    How the hell am I supposed to get this QD female connector on my air hose off the built in male fitting on the rifle?  I can’t see any non-destructive way to do this. 

    Help!!

    Can you just degas the gun? With the tank valve shut, the hose should bleed down as the gun degasses…

    Go to your back yard range and shoot tethered until you're out of air.

    Please post pics of targets, etc 😃

    Shame to waste all that air.

    Above all be safe!

    If I understand your situation correctly.

    – Close the valve on the guppy

    – Then loosen (just a slight crack) the hose connection at the valve until you hear air and STOP.

    – This will slowly bleed off hose pressure allowing you to remove the QD connector.

    I believe discharge port is for that. Just crack open the cga347 If it's a scba you're talking about.

    My first thought is to shoot the pressure down until you can unscrew something. The CGA347 is probably your best bet. I think this is your safest route. Some "hand tight only" CGA347's have an area where you could put a wrench on them to assist with unscrewing. 

    Then I thought, maybe you can unscrew the pressure gauge on the rifle (slowly, of course). This would bleed out all the air. 

    If this doesn't work or isn't an option, you might be able to unscrew a fitting somewhere in your assembly. Best to do this at a more solid point of the setup like, near the CGA. I would NOT attempt this near the foster quick connect. 

    It's hard to give better advise not knowing specifically what equipment you're working with. A pic would be very helpful.

    Please wear safety glasses, ear protection, and gloves to help avoid injury to yourself!

    Doesn’t your guppy have a bleed valve.  Mine does.  Thought they all did.  Small knob right side 

    OK forget that I understand you took the hose off the guppy and put it on the other tank.  Sorry about that.

    That should work.

    If the valve is closed why couldn’t he just loosen the hose where he connected it to the tank originally ?   I think some one suggested that.   He’s not connected to the guppy tank he just used the hose from it.  Unless I’m miss understanding

    All those ideas are good however cracking the hose is potentially more dangerous than shooting down your gun with guppy valve closed and when it gets around 1100 psi crack the air pressure guage on your rifle. I get nervous when putting stress on hoses under pressure. I would rather do it at the pressure guage unless you have no other alternative.

    Again he’s not connected to the guppy tank?  He’s not going to be able to shoot down the larger tank.

    HUH? If he closes the tank valve then he is just bleeding the gun and hose, right? or am I missing something?

    Tough to help without seeing the mystery valve assembly with 2 valves on it. "The other was a different setup. It only had the on/off knob and another valve."

    I think there's a few of us that would like to know what kind of progress you've made or if you've figured out a solution. Hope things are up and running for you again.

    I think you are making it a big deal than it really is. Like others have suggested. Loosening the fill port till it slowly bleed, there will be threads still holding it from shooting out. Or you can loosen the gauge, it will also bleed out. Or shoot it down. Next time if you're filling your tank that doesn't have a bleed valve, use a fill station that has one before connecting to the tank.

    Correct. Makes sure you have enough threads left.

    Be safe.

    Firing down would be safetst it seems. Bleeding advice above all sound pretty good – with due caustion-. Should you have the 347 "handtight" fitting you should be safe simply unscrewing it. 

     Let us all know and post up a picture of you adapters as you'll not be the last to do this.

    Like has been said turn valve off at tank, shoot gun down hose has 3000 psi once gun pressure drops the transfer port valve will open to allow the air that's in the line to bleed in do this down to below 500 psi or less then you can unscrew the line from the fitting slowly allowing the remaining air in the line to safely drain off without risking stripping threads
