CO2 Tank - Regulator problems

[Kieran the Human]

So I just bought a CO2 tank from Munster CO2 and I had bought a micromatic regulator a few months ago (getting my kegging equipment over time). The female thread on the regulator is a wider diameter than the male thread on the tank - has anyone ever come across this? And if so is there an adapter you can get for it?

[Kieran the Human]

I'm thinking even a smaller female thread for the regulator would sort the problem...although I'm totally new to kegging so any advice would be great

I think this is the case with any regulators from the states they have a slightly diferent standard fitting diameter. This happenned me when i bought a mixed gas reg . The soultion is to swap it out with a spare one - in your case its a c02 reg , a fire extinguisher end fitting would solve your problem , . i have a few here from a couple of extinguishers ive used. based in Galway though,there are plenty more on here who should have that that might be closer . Pm me if needs be

a threaded male to female reducer would do it I think...effectively reducing the diameter of your female end... making your male end fit better.   .... (I really am immature, can't continue typing like this and not smile)

Do you know the diameters?... tricky to measure. Maybe bring to a good plumbing suppliers who can try a few out.

Or try googling 'Male Enlargement products' .... I've got a few emails recently, - might be just want you need.

Hard to measure accurately but the male thread on the tank seems to be 20mm and the female thread on the regulator seems to be 30mm - I'm wondering if a normal tank connector would do the trick, might try that if I can get it in the right size. Might say it to the Munster CO2 as that's where I got it, they'd surely have fire ex. fittings.

yeah montofk, my male fitting is too small for my female - story of my life

something like these... http://www.amazon.com/Parker-Fitting-Reducing-Bushing-Female/dp/B000FN1MY0/ref=pd_sim_indust_1

Tricky to measure without calipers or something....try the plumbing shop, trial and error rather than being uncertain with measurements.

Cheers, I'll try to get a smaller female fitting from the hardware store - I'll have to go with an adapter if that doesn't work

Turns out I only need to replace the female nut on the regulator with a 7/8 inch one - sorted

Result BB!
Did you unscrew the shaft from the reg. body to get the nut off?
Was the correct nut easy to get?

[Kieran the Human]

Hi John, haven't actually sorted this yet - having trouble getting the shaft off the regulator and the male end on the tank seems to be 1/2" not what I had thought originally - gonna bring it into the hardware on monday and see if they have an adapter - disaster

Rather than arsing in your local Hardware store, go armed with the correct thread for the Cylinder...

CO2 Threaded Fittings
-------------------------
Throughout the world, carbon dioxide cylinder valves have a special thread. In Europe, Africa and much of Australasia,
the thread conforms to British Standard BS 341 Part 1 No. 8 (0.860 in x 14 TPI) or the direct European equivalent
(DIN 477 No. 6). These threads are in effect interchangeable.

American CGA 320 and Japanese JIS B 8246 CO2 threads are different and are not compatible with each other nor with
BS or DIN CO2 threads.

Take this kind of a pic. I might be able to answer this question.

I was talking to David Hickey from Munster CO2, he has a spare nut for my regulator that will fit the tank - so that should sort that  -cheers for all the advice lads
