i was planning just to remove the valve (the bit with the pin on) and leave the brass fitting on. but i cant unscrew the stupid thing! so i might have to remove the whole brass fitting. If not ill just cut it off and weld a fitting on the end!

Why bother, I have several rebuilded and tested oxygen bottles with different treaded neck available. 1/2 bso or 3/8 bsp, even 1 with a 3/8 hydraulic hose fitted on.

Ill happily dismantle a couple of bottles for you Alan...

BTW ...The thread on the steel bottle is a std BSP Size ....3/8 as I recall.

The tread I found on the sodastream bottles over here is M18*1.5
Handy as that is the metric version of 3/8 bsp.So getting more common over here each year;

If you remove the whole brass fitting it is definatly a 3/8 below.

cheers chaps, ive removed the brass fitting and they both are 3/8bsp. The first one came off easily but the second was on rather tight! isnt it always the case. Ive also got a smaller bottle, similar to a sodastream bottle that i think is out of a water fire extinguisher, so might put that in as well (that also had a brass fitting onto a 3/, so might have all three in!

If you have gone to a bigger ram, what have you done with your old one ?

nothing at the moment, but i think its more or less knackerd! it had new seals put in for the world champs, but it seemed to start leaking within a few events. i think the cylinder walls have got damaged.

If M18*1.5 is the metric version of 3/8 bsp whats the metric version of 1/4 bsp ?
