Air Filling Adapter for Hatsan Flash

[keninsc]

I was given a Hatsan Flash as a gift a few months back.
After looking at ways to fill the gun I found the best solution for me was to just buy one of those Chinese compressors. Getting too old to carry around tanks and we live quite a ways out to get to any shop.
Then I ordered a scope for it (this is getting expensive)
Started looking at it and found that I needed a way to fill it and none of the adapters with the rifle or the compressor are big enough.
Now I find out that I need some sort of adapter to go between the air fill nozzle and the hose from the compressor with the snap fitting.
The male thread on the fill nozzle appears to be about 1/8-1/4", a male fitting. I suppose it's metric but I cannot find a description anywhere on it.
So, do I buy a new fill nozzle for the rifle or an adapter from that nozzle to the compressor snap style fitting?
Just not sure what I need at this point

Hello. I am very new to air guns, never owned or operated it.
I have Hatsan Flash that I trying to fill up with manual pump. I pumped already must be 400 times but gage not moving up at all from present 100 bar.
I checked line from pump and connections. All are air tight. The only I can hear air hissing when I pumping at probe when it's inserted into airgun cylinder.
I already replaced O-rings in the probe (just in the case) The holes on the probe and air gun facing each other, probe inserted all the way in. Does anything needs to be opened in airgun cylinder to start receiving air?

Try cocking the gun before you pump, this may help seat the valve and allow it to fill.
