JJ bov and CE - Page 4

Dave Sutton · September 14th, 2012, 02:00 PM

No, we use 3/4 inch thread cylinders, which are VERY close to M26, so close that people mistakenly thread 3/4 valves into M26 cylinders at times. This is not a good thing... insufficient thread engagement and different O-Ring sealing profiles. Plus, M26 cylinders are not US DOT approved, so cannot be hydro-tested later. In the old days we used to import Faber bottles from the UK for use here, as we liked the non blowout-disc valves and the steel bottles (this was when all of the available bottles here were aluminum), and just "didn't worry" about hydro testing, etc. I still have a few here but generally they are unknown. In the very early Inspriration days M26 and non-DFOT cylinders found their way here in some limited quantities as well (there was no other option for a short time).

Do you also use the M26 in the US ?
I have one on the JJ on the Oxygen side... CE...

Your point is what exactly?

I bought my JJ prior to CE and it came with DIN regulators, but if I had bought the CE version I'd have spent £20 buying a DIN fitting for the O2 first stage.

If you want to spend your life getting screwed over by CE, just do it and shut up about it. Me, I don't bother about CE and it doesn't bother me.

Are we talking about the same thing here? Are you saying you use a 3/4" regulator valve (hand-wheel) rather than DIN G5/8?

Or are you talking about the cylinder neck size (M25x2, not M26 here in UK)?

Just for my sanity - the blow-out-disk is part of the valve (in the Inspo case made by APD) and not the cylinder (made by Faber).

Perhaps I now confused everyone...

M26 cylinders?
The M26 is only in the valve / first stage not in the cylinder.

Dave, M26 is not a cylinder thing, it's a valve and regulator thing.

The pillar valves are still M25*2 threads where they screw into the cylinder. M26 replaces DIN (G5/8) on valves and regulators meant for enhanced oxygen mixes.

I leave the unit as it came , CE.

If something happens to me while diving it, and i have made change on it the insurance will never pay up and i leave my family whit a lot of problems.... and if i change it they will not fill my cylinder in shops.

Got it.. I replied as if the question was "do you use M25*2" and not what was actually asked.

"lost in translation" between SAE and Metric threads

Thanks,

I dont really get the problem with M26 on the O2 bottle. The reg is never going to be used for anything else, fill adapter is a couple of quid. You need a handed valve for each bottle anyway so you've already got inconsistencies there. Mk15's have been using dissimilar fittings for dil and O2 (albeit a-clamp variants) for 4 decades, I quite like the extra layer of anti-f**k-up. Seems like a lot of wasted energy over something not particularly worth getting overheated about.
