Thanks again Harry. I can only send pics via mobile so would need a number. The nut itself is 25mm across which after looking at next doors co2 appears to be standard, the difference with mine is that it is 18mm deep--several mm deeper than next doors. Both are 2kg cylinders. Terry

Thanks very much for the super quick reply. I've had a look at the nut and its actually the neck of the nozzle thats sheared off. "It just broke in my hands". When he came back with the new nozzle which he was going to replace for free and tried to fit it, the nozzle was just very slack and would not point, this being due to the new type of fitting on my old extinguisher. Thanks in advance, Terry.
