clochmerle 2 Posted April 19, 2017 Share Posted April 19, 2017 Hi, Anyone seen a composite gas bottle for sale in nz? seem like a good option for marine, not too expensive, but cannot find anyone here that sells them. http://www.southernseasmarine.com.au/composite-gas-bottle-cylinder Quote Link to post Share on other sites
Island Time 1,235 Posted April 19, 2017 Share Posted April 19, 2017 Never yet seen one for sale. I had to throw out a couple bought offshore as they had different fittings to NZ bottles. Shame, they are cool, and you can see the liquid level through the side! Quote Link to post Share on other sites
Island Time 1,235 Posted April 19, 2017 Share Posted April 19, 2017 without looking at the particular standards, Ausy and the USA both accept them, and our standards normally mirror theirs? Quote Link to post Share on other sites
1paulg 17 Posted April 19, 2017 Share Posted April 19, 2017 I have two that came with my boat - they are Aussie . Unfortunately as KM mentioned - no one will fill them here as the manufacturer hasn't bothered to go through the red tape and register them in NZ which is a shame as they are so convenient for the marine environment - they don't rust and you see the liquid levels . I think there is a method of cross filling them from a full bottle however I haven't found it very successful ( maybe my technique isn't quite right - but you lose a bit of the gas) . I got them filled when I cruised in the Islands where they didn't worry about the certification and really wish I could get them filled here.. Quote Link to post Share on other sites
Island Time 1,235 Posted April 19, 2017 Share Posted April 19, 2017 The correct method is not to open the bleed valve, but to pump the gas into the bottle under pressure to specified weight of gas. Most wont have the gear for that. The dodgy way via gravity is to put one bottle up high, and the one to be filled down low. Open both valves, and then the bleed valve in the lower one once the sound stops. When white liquid comes out the bleed valve, its (over) full. That's the common way in 3rd world countries, and it does vent a fair bit of gas. DONT SMOKE!!! Quote Link to post Share on other sites
Island Time 1,235 Posted April 19, 2017 Share Posted April 19, 2017 Oh yeah, that will overfill the bottles, and they will then vent if left in the sun or get too hot. Make certain your gas locker IS sealed to the boat, and vents overboard as it should. Quote Link to post Share on other sites
Black Panther 1,584 Posted April 20, 2017 Share Posted April 20, 2017 I've seen a big gas bottle go boom, it was like a massive bomb going off. You would not survive. Quote Link to post Share on other sites
ScottiE 174 Posted April 20, 2017 Share Posted April 20, 2017 Yeh - f*ck that - I'd rather just change my cooking system if i could no longer fill the 4kg bottle. Quote Link to post Share on other sites
Island Time 1,235 Posted April 20, 2017 Share Posted April 20, 2017 yeah, LPG is WAY more dangerous than petrol. It really is a bomb. Take care - its not hard to do, just be sensible... Quote Link to post Share on other sites
Vorpal Blade 89 Posted April 20, 2017 Share Posted April 20, 2017 but the 9kg swap-a-bottle is never going to fit in our gas bottle locker. It was built for the 4kg jobs, we carry 2 off them, one for the cooker and the other for the BBQ. Quote Link to post Share on other sites
Island Time 1,235 Posted April 20, 2017 Share Posted April 20, 2017 Same, VB, but Island Time feeds both the Boat and the BBQ from one bottle - the other is a spare. 2 x 4KG alloy bottles, no way to fit a 9 KG.... Quote Link to post Share on other sites

1paulg 17 Posted April 20, 2017 Share Posted April 20, 2017 I have tried filling one using gravity but it isn't straight forward as you need the full one inverted so the liquid will run out and the empty one obviously below it ... As IT said when you open the bleed you do lose some -Needs to be a well ventilated place but I never really achieved a very satisfactory fill so gave up. Possibly my timing of releasing the bleed valve was wrong ? Quote Link to post Share on other sites
harrytom 642 Posted April 20, 2017 Share Posted April 20, 2017 we get 4kg bottles filled in manurewa at the www.cylex.co.nz/company/wormald+cylinder+test+station-17952672.html most are doing swappa bottles 9kg due to compliance costs of running a fill station,hence why 4kg may become obsolete Quote Link to post Share on other sites
ScottiE 174 Posted April 20, 2017 Share Posted April 20, 2017 I wonder what the anual statistics are on explosions, injuries or deaths at NZ at petrol stations. Presumably we would "hear" about the first - most other noteworthy news is crap in comparison! But seriously I'm assuming that you'll still be able to go to the bigger filling stations - just a bit further to go. In the end I think I'll end up with a spare set of bottles - that way you can have a full set ready to go and fill the empty set "on your way past" a bigger station. A little more inconvenient but what else can you do if the free market economy dictates that its no longer viable to have multiple filling stations throughout the city due to safety compliance concerns (as opposed to actual safety concerns which presumably they would have already actually addressed by now rather than just expend multiple forecourts and attendants!)

marinheiro 352 Posted April 20, 2017 Share Posted April 20, 2017 Of the Petrol Stations, Caltex seem to be the most likely to have LPG bottle refilling, I have used the one in Constellation Dr on occasion. Some hire companíes have filling facilities and there is Rockgas out in Henderson Apart from the above, look for the industrial gas suppliers, in Warkworth we get LPG from the local BOC agent, Mahurangi Sheetmetals Quote Link to post Share on other sites
Black Panther 1,584 Posted April 20, 2017 Share Posted April 20, 2017 There are three places around here that do them. Quote Link to post Share on other sites
