superico Posted May 5, 2012 Report Share Posted May 5, 2012 hi all, i will be ordering a custom CO2 system soon :happy1: and would like to know the type of connection used here in NZ cheers superico Quote Link to comment Share on other sites More sharing options...
phoenix44 Posted May 5, 2012 Report Share Posted May 5, 2012 Just buy one of these and then a normal CO2 bottle from NZ. http://www.ebay.com/itm/UP-CO2-regulator-with-solenoid-magnetic-valve-control-/250881122073?pt=LH_DefaultDomain_0&hash=item3a69ae1f19 You don't have to mess around with modding anything. Alternatively HFF may still have their deals for a full system. Have you spoken to them yet? Quote Link to comment Share on other sites More sharing options...
Joe Posted May 5, 2012 Report Share Posted May 5, 2012 The connection thread NZ uses is DIN 477. Quote Link to comment Share on other sites More sharing options...

Jellymeat Posted May 6, 2012 Report Share Posted May 6, 2012 I am also have the same thoughts to superico. So i have been doing some research as well about the thread of the bottles. The connection thread NZ uses is DIN 477. On this website it say that DIN 477 is a non preferred cylinder neck thread. Stated on page 49 Dose this mean its still usable in NZ? http://www.epa.govt.nz/Publications/Guide%20to%20Gas%20Cylinders%202011.pdf I have also gone through and old thread about co2 cylinders http://www.fnzas.org.nz/fishroom/viewtopic.php?f=3&t=11047 Which says that NZ and OZ use the same thread as the british which that thread is Din 477 DubbieBoy posted a link on that thread about the different cylinders neck threads and OZ had a different thread size AS2473 Type 30 http://www.teamonslaught.fsnet.co.uk/co2_info.htm To me this is kind of confusing But do the cylinders with the Din477 still meet NZ regulations and standards?

livingart Posted May 6, 2012 Report Share Posted May 6, 2012 i think a lot of the medical fittings in nz are still Din477 Quote Link to comment Share on other sites More sharing options...
