300 or 232
whatever you do, don't use a 232 bar fill rig on a 300 bar bottle.
THEY ARE MADE DIFFERENTLY FOR A REASON
A 300 bar bottle will be marked ps300bar, and has around 13 threads in its fitting, where a 232 bar has about 6 - 9.
You can use a 300 bar fill rig on a 232 bar, but not the other way round.
An a frame valve will look like a square block about 30mm sq, with an opening on one side which has an o ring in the face.
An a frame adapter goes over this valve and has either a bsp outlet or a din threaded outlet.
The din thread is about 25mm in diameter and will be a female thread.
I hope this helps, if there's anything else i can help with please ask.
