yeh for HPA basically screwing into a big air bottle to fill little air bottles with haha not that sure myself really. is that one with a purge valve as well?
You might think that but considering I paid £80 for it from jp and even cheap ones from china on eBay cost over £60 so it's not expensive compared to those. But fair play if you find a cheaper one!
Oh thats a completely different type of connection, If you need that one then that's a different story there really cheap. But I would make sure thats the right connection you need. I thought they were the old type?
Edit Yeah that only connects to K, J and H valves...i.e.
The one I have (which is the expensive option) is called a din Valve
