A-clamps to DIN

[steve anderson]

Is it possible to convert a regulator first stage with an A-clamp fitting to a DIN fitting?

For every reg I know yes. You just buy the new fitting, take the old one off (big spanner required) then fit the new one. Its easy to do or a couple of minute job for a dive shop

Err.. This only holds true for more modern valves, where the manufacturer has designed it to be so.. European valves are more likely to be OK...I'd kind of say that a 'high percentage' of valves can be converted. Note also that DIN valves are normally good to 300bar, where A-Clamp ones only needed to go to 232bar. The pressure rating is normally stamped on the yoke of the clamp and (I believe) relates primarily to the stress capability of that yoke, although the valve seats etc. will probably be designed to work to that limit.

Cylinders, certainly, have different lengths of thread for 232 and 300 bar pillar valves. The 300bar ones are longer, so that you can fit a 300bar rated connection to any DIN Cylinder, but a lower rated connector will not reach in far enough to make a seal...

Some of the conversion bits are V. expensive - Check out if you might be better off upgrading and either selling your old reg to another diver (good source of kit for trainees!) or using it as a 'Pony' reg...

If you plan to make the mod yourself, be VERY careful. the DIN/A-Clamp bit is at Cylinder pressure!!

Good Luck.
PS - I went DIN a while back, and like them...

Agree with what has already been said but bear in mind the following.


Check what rating your Dv is.
DO NOT put a 300bar Din fitting on a 232 bar Rated REG.

Check your contents guage to ensure it goes up to 300Bar, don't or certainly didn't when I was purchasing my regs.

I see many people with DIN fitting tanks with no plug in them, when not in use.
This allows dirt and all sorts of things in, which will be blown into the DV when you connect it up. Yes there is a filter but this will become clogged up quicker.

Also I see people with Plastic plugs. Always use the metal plugs,
WHY?

When I was buying my DIN fitting tanks I was lucky enough to be present when a customer came into the shop with a dented Din
pillar valve. He had had a plastic plug in it when the top had received a hard knock. It squashed the hole only very slightly but enough to prevent a DV DIN being screwed in. The only solution was a new pillar valve at ?70.
He was told had he had a metal plug in then it was unlikely the hole would have been squashed.
So be warned.

While a DIN plug is probably a good idea, you should still give the pillar valve a quick blast to blow out any water/grit/dust before connecting the first stage.
