Scuba Forum / UK Scuba / November 2003Co2 cartridge re-fills
Anyone know of a cheap supplier of CO2 cartridge re-fills for Aquatec junior auto SMB's. Cartridges are 16g threaded 3/8 UNF. cheers, Steve Haddow > Anyone know of a cheap supplier of CO2 cartridge re-fills for Aquatec junior > auto SMB's. Cartridges are 16g threaded 3/8 UNF. which size is that? I've seen the ones for the JR signal marker (little yellow one) as cartridges for little air dusters for computers 12oz from http://www.boysstuff.co.uk/product.asp?id=134910 +2 free for 9.95 I have no idea if that is a good price or not >Anyone know of a cheap supplier of CO2 cartridge re-fills for Aquatec junior >auto SMB's.

Or from just searching online I see two for ?4.99, think that's about the standard price for threaded ones: http://www.wiggle.co.uk/v2_product_detail.asp?ProdID=5300004673 > Anyone know of a cheap supplier of CO2 cartridge re-fills for Aquatec junior > auto SMB's.

Not totally on the same point, but why do they have CO2 cartridges, and why are they bought over air ones, considering the problem and cost in getting them filled / replaced after every dive where you use your DSMB?

Most people use the CO2 cartridge SMB's for emergency only. For this purpose they're ideal as - they're a lot smaller than the ones with 0.1L bottles - you always know the bottle's full. - Keith > Most people use the CO2 cartridge SMB's for emergency only. > For this purpose they're ideal as > - they're a lot smaller than the ones with 0.1L bottles > - you always know the bottle's full. Ahhh - that makes sense then. :O) David > > Most people use the CO2 cartridge SMB's for emergency only. > > For this purpose they're ideal as > > - they're a lot smaller than the ones with 0.1L bottles > > - you always know the bottle's full. I didn't follow this thread from the beginning, so forgive me if my question has already been addressed. On my side of the Atlantic, CO2 cartridges are small, sealed bottles, usually with a screw thread on the neck, but with no valve or opening. They are activated by a pin that punctures the seal, allowing the CO2 to escape rather quickly. They are not refillable. Is this not the case in the UK?

You pull a cord on the SMB, which presumably causes the cartridge to be punctured, and the gas then fills the SMB. - Keith > Most people use the CO2 cartridge SMB's for emergency only. > For this purpose they're ideal as > - they're a lot smaller than the ones with 0.1L bottles > - you always know the bottle's full. Do the bottles leak at all? A friend at work as a private plane, and to get the life-jackets through whatever test they have to pass he has to weigh the bottles annually to see if they have leaked. Is this leaking the same for diving, or is it just being anal for aircraft? Cheers Matt. > Do the bottles leak at all?

Out od curiosity, have any commercial planes managed to land on water without breaking up and/or sinking before anyone can get out with those wonderful life jackets? - Keith > > Do the bottles leak at all?

Not big ones, that's for sure. As soon as you hit the water, the wing tips come off, smashes the engine and fuel lines up and the whole thing goes up in a big fireball.

There are some examples on: http://aviation-safety.net/events/RECW.shtml http://aviation-safety.net/events/REED.shtml http://aviation-safety.net/database/1952/520727-0.htm http://aviation-safety.net/database/1996/960405-1.htm http://aviation-safety.net/database/1982/820910-0.htm http://aviation-safety.net/database/1978/780508-1.htm http://aviation-safety.net/database/1984/840228-0.htm http://aviation-safety.net/database/1969/690113-0.htm So it could could be good that the life jacket works.
