The hole in my -insert obscure unknown Russian- disc is too small to get the normal pump head in and I had to get a screw-on 90 degree adapter for the valve. Problem is the pressure just makes the pump head blow off the adapter. It's a bit rubbish.
The tube on the adapter is a smaller diameter than a normal tyre valve, so the pump head doesn't stay on. Just slips off once the pressure goes up. I'm currently resorting to using a cable tie to hold it on, then cut it off afterwards. Not ideal.
