    Default Kral Puncher Jumbo

    Good day,

    I received my rifle today and I can't find a lot of information about this.

    I have the mini compressor - tested no leaks.
    As soon as I plug it into the gun nothing happens - leaking.
    I pushed the probe that came with the gun into the gun as shown in the pictures - this can't release remove now?

    What am I doing wrong and or how to you remove the plug?

    Kindly please assist?

    I hope someone will chip in, but I once read, with some guns, if empty you must first cock it, then fill it, or something along those lines. Google a bit around this suggestion, you might get something. But someone here will know and help you, but most are out shooting or watching rugby now.

    The gun is currently at 150 bar, it came like this out of the box. I can feel the leak between the adapter and the nipple fitting in the middle. The end that goes into the compressor seems like it is not leaking there...

    Show us a pic of where you feel the leak. All fittings and adapters need to have plummer's tape where it screws in.

    Please see the circled area, this is where I feel the leak. The compressor hose fitting has two small o-rings inside.

    Do those o-rings look flattened in any way? Maybe a pic of the o-rings?

    The o-rings should be fine, the compressor is brand new. The are only two o-rings in the compressor hose fitting. I see no more o-rings in the rest of the parts. I tested the compressor with the stop valve and it is building air nicely. I have no idea, totally new this...

    You need plumbing (ptfe) tape, put it on the fill adaptor (the threaded part) that came with the rifle. Then connect it to the female nipple. Tighten it nicely and dont keep removing it, the leak will stop.

    It is a simple thread that connects the fitting to the quick connector, wrap a good few layers of PTFE tape on the thread being mindful that you need to wrap it in the same direction that the thread will screw in so you dont have it coming off when you screw the fittings together. The tape will seal the fittings and you are good to go.
