Folks who replied to me so far... Many thanks, I really appreciate the advice. I did not want to do anything unsafe, that is why am asking..

RACER
I have already purchased a WOQOD bottle of gas (sheffaf) and bought the adapter as well, the regulator side being snap-on type.. So far so good. But unfortunately when I connect one end of the hose to this regulator and the bottle, the other end on the BBQ grill (which I shipped from the US)is unfortunately a different type connection, requires some type of adapter. What I have on the grill side is a metal-to-metal seal, nut type connection, going to the burners..
I need to find an adapter/fitting to be able to hook up the hose to this grill.
